Oxygen scavengers are added to remove residual dissolved oxygen in boiler feed water that can cause corrosion in a steam generating plant. It is important that levels of oxygen scavengers be routinely checked to prevent against corrosion and ensure that equipment is working efficiently.

HI-97710 is designed to measure pH and low levels of free and total chlorine in water up to 5.00 mg\/L (ppm).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eAdvanced optical system\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to +\/- 1 nm and offers 25% increase in light efficiency.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e6.5 to 8.5 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Resolution\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e0.1 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e±0.1 pH @ 25°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Method\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eadaptation of Phenol Red method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Range\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e0.00 to 5.00 mg\/L (as Cl\u003csub\u003e2\u003c\/sub\u003e)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Resolution\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e0.01 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e±0.03 mg\/L ±3% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Chlorine Range\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e0.00 to 5.00 mg\/L (as Cl\u003csub\u003e2\u003c\/sub\u003e)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Chlorine Resolution\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e0.01 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Chlorine Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e±0.03 mg\/L ±3% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChlorine Method\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eadaptation of the EPA 330.5 DPD method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Source\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eLight emitting diode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Detector\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003esilicon photocell with narrow band interference filter @ 525 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass Filter Bandwidth\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e8 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass Filter Wavelength Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e±1.0 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCuvette Type\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eround, 24.6 mm diameter (22 mm inside)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGLP\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003edate, time of last calibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e128 x 64 pixel B\/W LCD with backlight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogging Type\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eautomatic logging\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogging Memory\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e50 measurement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Type\/Life\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e1.5V AA battery (3 pcs.) \/ \u0026gt;

The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.\u003c\/p\u003e \u003ch3\u003eAbout Dissolved Oxygen\u003c\/h3\u003e \u003cp\u003eDissolved oxygen analysis measures the amount of gaseous oxygen (O2) dissolved in an aqueous solution. Dissolved oxygen is one of the most important parameters in aquatic systems. This gas is required for metabolism by aerobic organisms and also influences inorganic chemical reactions. Therefore, knowledge of the solubility and dynamics of oxygen distribution is essential to interpreting both biological and chemical processes with water bodies. Oxygen gets into water by diffusion from the surrounding air by aeration (rapid movement) and as a product of photosynthesis.\u003c\/p\u003e \u003cp\u003eThe amount of oxygen that can dissolve in pure water is inversely proportional to the temperature of the water; the warmer the water, the less dissolved oxygen is present.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0.0 to 10.0 mg\/L (ppm) (as O2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.1 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.4 mg\/L ±3% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eAdaptation of Standard Methods for Examination of Water and Wastewater (18th edition) Azide modified Winkler method reaction causes a yellow tint in sample\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Source\u003c\/td\u003e\n\u003ctd\u003eLight emitting diode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Detector\u003c\/td\u003e\n\u003ctd\u003eSilicon photocell with narrow band interference filter @ 466 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass Filter Bandwidth\u003c\/td\u003e\n\u003ctd\u003e8 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass Filter Wavelength Accuracy\u003c\/td\u003e\n\u003ctd\u003e±1.0 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCuvette Type\u003c\/td\u003e\n\u003ctd\u003eround, 24.6 mm diameter (22 mm inside)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGLP\u003c\/td\u003e\n\u003ctd\u003eDate, time of last calibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e128 x 64 pixel B\/W LCD with backlight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogging Type\u003c\/td\u003e\n\u003ctd\u003eautomatic logging\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogging Memory\u003c\/td\u003e\n\u003ctd\u003e50 measurement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Type\/Life\u003c\/td\u003e\n\u003ctd\u003e1.5V AA battery (3 pcs.) \/ \u0026gt; 800 measurements (without backlight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutomatic Shut-Off\u003c\/td\u003e\n\u003ctd\u003eAfter 15 minutes of inactivity (30 minutes before a READ measurement)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironment\u003c\/td\u003e\n\u003ctd\u003e0 to 50°C (32 to 122°F); relative humidity: 100% (IP 67, floating case)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e380g with batteries\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e142.5 x 102.5 x 50.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering Information\u003c\/td\u003e\n\u003ctd\u003eHI-97732 is supplied with cuvettes (2), caps (2), plastic inserts for cuvettes (2), 1.5V AA batteries (3), instruction manual, and instrument quality certificate.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.hannainstruments.co.uk\/modules\/teapotknowledgehub\/uploads\/man97732_10_19-60bf488a7d3ad.pdf\" target=\"_blank\"\u003eHI-97732 Dissolved Oxygen Photometer (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640105640309,"sku":"HI-97732","price":502.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-97732-dissolved-oxygen-photometer-range-00-to-100-mgl.jpg?v=1791581448"}],"url":"https:\/\/testallwater.co.uk\/collections\/fish-and-shellfish-farming.oembed?page=3","provider":"Test All Water","version":"1.0","type":"link"}
