Rinse the membrane (supplied with meter) with electrolyte solution while shaking it gently. Refill with clean electrolyte solution.\u003cbr\u003e4. Gently tap the sides of the membrane with the fingertip to ensure that no air bubbles remain trapped. To avoid damaging the membrane, do not tap the membrane directly on the bottom.\u003cbr\u003e5. Place the O-Ring (suppield with membranes) properly inside the membrane cap.\u003cbr\u003e6. With the sensor facing down, screw the cap clockwise.

All LCD tags are displayed and a beep is heard while the instrument performs a test.\u003cbr\u003e9. The \"COND\" message will be displayed for about 45 seconds to inform the user that the probe is in auto-conditioning mode (automatic polarization).\u003cbr\u003e10.

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"},{"product_id":"hanna-instruments-hi-98198-opdo-optical-dissolved-oxygen-meter","title":"Hanna Instruments HI-98198 opdo™ Optical Dissolved Oxygen Meter","description":"\u003cp\u003eThe HI-98198 opdo™ meter is a rugged, portable dedicated dissolved oxygen (DO) meter designed for fresh and saltwater measurements of dissolved oxygen.
