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-97704 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\u003eAdvanced LED optical system\u003c\/h3\u003e \u003cp\u003eLEDs have a much higher luminous efficiency, providing more light while using less power.

This is an advantage over sulphite treatment because it does not produce any dissolved solids in the boiled water. Hydrazine is also used as an energy source in fuel elements, as a reducing agent for metal recovery, and as an intermediate in the production of insecticides, herbicides, pharmaceuticals, and many other chemical products.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0 to 400 μg\/L (as N2H4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1 μg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±4% of full scale\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eAdaptation of the ASTM Manual of Water and Environmental Technology, method D1385-88 for natural and treated water\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: 0 to 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-97704 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\u003ctr\u003e\n\u003ctd\u003eReagents and CAL Check Standards\u003c\/td\u003e\n\u003ctd\u003eHI-97704-11 CAL Check Standard Cuvettes HI-93704-01 Reagents 100 tests HI-93704-03 Reagents 300 tests\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\/man97704_09_191-60b8e29d75ad5.pdf\" target=\"_blank\"\u003eHI-97704 Hydrazine Photometer (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640103018869,"sku":"HI-97704","price":502.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-97704-hydrazine-photometer-range-0-to-400-ugl.jpg?v=1791581371","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-97704-hydrazine-photometer-range-0-to-400-ug-l","provider":"Test All Water","version":"1.0","type":"link"}
