Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI98129 Color: Black

The Hanna Instruments HI 98129 is a multi-parameter tester that measures pH, electro-conductivity (EC), total dissolved solids (TDS), and temperature, and features automatic temperature compensation (ATC), an LCD screen, automatic shut-off, and a waterproof body that floats in water. The tester automatically compensates for the effects of temperature when taking pH and EC/TDS readings, so additional measurements and manual temperature entries are unnecessary. The HI 98129 meter has a replaceable pH electrode with an extendable cloth junction, and an EC/TDS graphite electrode that is resistant to salts and other corrosives. These features extend the life of the meter by allowing for replacement of the electrodes. Calibration is automatic at one or two points, with two sets of memorized buffer values (pH 4.01/7.01/10.01 or 4.01/6.86/9.18). The EC/TDS conversion factor and temperature compensation coefficient (&Beta) is user-selectable. The tester functions in temperatures of 0.0 to 60.0 degrees C/32.0 to 140...
