Description HI-98120 Floating ORP & Temperature Measuring Meter The Hanna HI 98120 is a waterproof ORP and temperature meter. The housing has been completely sealed against humidity and designed to float. The temperature values can be displayed in °C or °F units. This Hanna HI-98120 Waterproof ORP & Temperature Meter is extremely useful when treating the pond with Potassium Permanganate, rather than keeping the pond purple for a set number of hours, using the Hanna HI-98120 Waterproof ORP you can keep the pond purple at a set number, much safer this way. The meter is factory calibrated and measurements are highly accurate with a unique stability indicator right on the LCD. This meter is also provided with battery level indication at start-up, and with a low battery symbol which warns the user when the batteries need to be replaced. In addition the Battery Error Prevention System (BEPS) avoids erroneous reading caused by low voltage level by turning the meter off. Key features Dual level LCD screen that displays simultaneous readings Automatic temperature compensation HOLD function freezes readings for ease of recording Floating, water resistant casing helps prevent accidental loss of meter during testing in difficult conditions Battery % level at start up and stability indicator helps ensure tester is in optimum working order Cartridge electrode – exclusive to Hanna Electrode replacement with stainless steel round connector means there are no pins to bend or break during replacement Exposed stainless steel temperature sensor facilitates faster and more accurate temperature measurement Supplied with Electrode removal tool, HI 73120 ORP/Redox electrode, batteries & instructions Range – mV ±1000 mV Range – Temperature -5.0 to 60.0°C / 23.0 to 140.0°F Resolution – mV 1 mV Resolution – Temperature 0.1°C / 0.1°F Accuracy – mV ±2 mV Accuracy – Temperature ±0.5°C / ±1°F Calibration factory calibrated ORP Electrode HI 73120 (included) Battery Type / Life 4 x 1.5V with BEPS / approx. 300 hours of continuous use; auto-off after 8 minutes of non-use Environment -5 to 50°C (23 to 122°F); RH max 100% Dimensions 163 x 40 x 26 mm (6.4 x 1.6 x 1.0″) Weight 100 g (3.5 oz.)
