The Hanna Instruments HI 98120 is a compact, factory-calibrated, oxygen reduction potential (ORP) and temperature tester that measures in millivolts (mV) and degrees C, has a dual-level LCD screen, a replaceable electrode cartridge with an extendable cloth junction, and a waterproof, dustproof housing that allows the tester to float. An ORP meter, also known as a redox potential tester, measures the oxidization or reduction capacity of a solution, and monitors chemical reactions and ion activity. It is commonly used for water-testing, pulp bleaching, and for biological sample analysis in swimming pools, cooling towers, waste water treatment, and industrial applications. The dual-level LCD screen simultaneously shows the current measurement and the current temperature. This meter has an exposed stainless steel temperature sensor to provide accurate temperature measurement. A stainless steel round connector eliminates bent or broken pins during electrode replacement. The meter comes with the HI 73120 ORP electrode, which has an extendable cloth junction to prolong electrode life. The waterproof, dustproof housing is sealed against humidity and allows the tester to float. The tester works with four 1.5V alkaline batteries (included) for up to 250 hours of continuous operation. An auto power-off feature turns the meter off after eight minutes of inactivity to extend the life of the batteries. The HI 98120 also comes with an electrode removal tool and instructions.Specifications ORP range+ or – 1000mVTemperature range-5.0 to 60.0 degrees C (23.0 to 140.0 degrees F)ORP resolution1mVTemperature resolution0.1 degrees C (0.1 degrees F)ORP accuracy+ or – 2mVTemperature accuracy+ or – .5 degrees C (1 degree F)Operating temperature-5 to 50 degrees C (23 to 122 degrees F)Operating relative humidity100 percentDimensions163 x 40 x 26mm/6.4 x 1.6 x 1.0 inches (H x W x D)Meter weight100g/3.5oz.H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to rig...
