This meter offers a superior optical system that utilises a reference detector and narrow band interference filters for extremely fast and repeatable measurements.\u003c\/p\u003e \u003cp\u003eThe HI-97735 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. 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-97735 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 LED optical system\u003c\/h3\u003e \u003cp\u003eLEDs have a much higher luminous efficiency, providing more light while using less power.

The concentration of these salts determines the water hardness, which can be expressed in calcium carbonate or magnesium carbonate. The sum of these two represents the total hardness level. In addition, water hardness is also related to the phenomenon of pipe rusting in water heating and cooling systems, reverse osmosis, and demineralisation plants.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" style=\"text-align:left;\"\u003e\u003cstrong\u003eTOTAL HARDNESS - LOW RANGE\u003c\/strong\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0 to 250 mg\/L (as CaCO3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy @ 25°C\u003c\/td\u003e\n\u003ctd\u003e±5mg\/L ±4% 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 recommended method 130.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" style=\"text-align:left;\"\u003e\u003cstrong\u003eTOTAL HARDNESS – MEDIUM RANGE\u003c\/strong\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e200 to 500 mg\/L (as CaCO3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy @ 25°C\u003c\/td\u003e\n\u003ctd\u003e±7mg\/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 recommended method 130.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" style=\"text-align:left;\"\u003e\u003cstrong\u003eTOTAL HARDNESS – HIGH RANGE\u003c\/strong\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e400 to 750 mg\/L (as CaCO3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy @ 25°C\u003c\/td\u003e\n\u003ctd\u003e±10mg\/L ±2% 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 recommended method 130.1\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\u003e466nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter bandwidth\u003c\/td\u003e\n\u003ctd\u003e8nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter wavelength accuracy\u003c\/td\u003e\n\u003ctd\u003e±1.0nm\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 24.6mm 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\/life\u003c\/td\u003e\n\u003ctd\u003eAlkaline 1.5 V AA (3) \/ \u0026gt;
