With a stable source of light the readings are fast and stable between your blank (zero) measurement and sample measurement.\u003c\/p\u003e \u003ch3\u003eHigh Efficiency Light Source:\u003c\/h3\u003e \u003cp\u003eLED light sources offer superior performance compared to tungsten lamps. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.\u003c\/p\u003e \u003ch3\u003eHigh Quality Filters:\u003c\/h3\u003e \u003cp\u003eImproved optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received. The end result is higher measurement stability and less wavelength error.\u003c\/p\u003e \u003ch3\u003eGreater Light Yield:\u003c\/h3\u003e \u003cp\u003eA focusing lens collects all of the light that exits the cuvette, eliminating errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.\u003c\/p\u003e \u003ch3\u003eCAL Check Functionality:\u003c\/h3\u003e \u003cp\u003eHanna’s exclusive CAL Check feature allows for performance verification and calibration of the meter using NIST traceable standards. Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify the accuracy of subsequent readings.\u003c\/p\u003e \u003ch3\u003eMultiple Measurement Methods:\u003c\/h3\u003e \u003cp\u003eUsers can select the use of powder reagents supplied in packets or the use of low cost liquid reagents supplied in a dropper bottle.\u003c\/p\u003e \u003ch3\u003eBuilt-in Reaction Timer:\u003c\/h3\u003e \u003cp\u003eWaiting the proper reaction time is of key importance when performing colorimetric measurements. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between sample measurements and users.\u003c\/p\u003e \u003ch3\u003eLarge Cuvette Size:\u003c\/h3\u003e \u003cp\u003eThe sample cell of the HI-97761 fits a round, glass cuvette with a 25 mm path length. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples.\u003c\/p\u003e \u003ch3\u003eIntuitive Dot Matrix Display:\u003c\/h3\u003e \u003cp\u003eThe HI-97761 is designed with a backlit, graphic LCD. With virtual keys, a battery status indicator, and error messages. Users will find the meter interface intuitive and easy to read. A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help.\u003c\/p\u003e \u003ch3\u003eAuto-off Protection:\u003c\/h3\u003e \u003cp\u003eThe meter uses three common AA batteries that allow for about 800 measurements to be taken. The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.\u003c\/p\u003e \u003ch3\u003eAbout the Photometer\u003c\/h3\u003e \u003cp\u003eHI-97761 is an advanced portable photometer for the measurement of Ultra Low Range Total Chlorine in water.

This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements, and customising the meter to user preferences.\u003c\/p\u003e \u003cp\u003eHI-97761 is waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a protected battery compartment that holds three AA batteries. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75\") by 37 mm (1.6\") and is backlit for easy viewing under all conditions.\u003c\/p\u003e \u003ch3\u003e\u003c\/h3\u003e \u003ch3\u003eAdvanced optical system\u003c\/h3\u003e \u003cp\u003eLED that generates very little heat.\u003c\/p\u003e \u003cp\u003e8 nm narrowband interference filter that is accurate to +\/- 1 nm and offers 25% increase in light efficiency.\u003c\/p\u003e \u003cp\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/p\u003e \u003cp\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Chlorine ULR Range\u003c\/td\u003e\n\u003ctd\u003e0.000 to 0.500 mg\/L (as Cl2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.001 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.020 mg\/L ±3% of reading at 25 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eAdaptation of the EPA Method 330.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" style=\"text-align:left;\"\u003e\u003cstrong\u003eMeasurement System\u003c\/strong\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight source\u003c\/td\u003e\n\u003ctd\u003eLight Emitting Diode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter\u003c\/td\u003e\n\u003ctd\u003e525 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter\u003c\/td\u003e\n\u003ctd\u003ebandwidth 8 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\u003eLight detector\u003c\/td\u003e\n\u003ctd\u003eSilicon photocell\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\u003cth colspan=\"2\" style=\"text-align:left;\"\u003e\u003cstrong\u003eAdditional Specifications\u003c\/strong\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuto logging\u003c\/td\u003e\n\u003ctd\u003e50 readings\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\u003eAuto-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\u003eBattery type\u003c\/td\u003e\n\u003ctd\u003e1.5 V AA Alkaline (3 pcs.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery life\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 800 measurements (without backlight)\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); 0 to 100% RH\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 (5.6 x 4.0 x 2.0\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (with batteries)\u003c\/td\u003e\n\u003ctd\u003e380 g (13.4 oz.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase ingress protection rating\u003c\/td\u003e\n\u003ctd\u003eIP67, floating case\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\/man97761_10_19-60b8e4ae1c2c9.pdf\" target=\"_blank\"\u003eHI-97761 Total Chlorine Photometer (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640107180405,"sku":"HI-97761C","price":736.53,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-97761c-total-chlorine-photometer-kit-ultra-low-range.jpg?v=1791581495","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-97761c-total-chlorine-photometer-kit-ultra-low-range","provider":"Test All Water","version":"1.0","type":"link"}
