Hanna Instruments HI 98121 Combination pH/ORP/Temperature Tester

Product Description

The HI 98121 pH/ORP/Temperature Tester is a waterproof combination pocket pH, Oxidation Reduction Potential (ORP), and temperature tester with a replaceable electrode and a non-clogging, replenishable fiber junction.

The meter features a large LCD screen for readability, an ergonomically designed waterproof casing, and automatic temperature compensation to eliminate the need for additional calculations. It has a replaceable electrode and renewable reference junction, which helps prolong the life of the tester.

The HI 98121 tester functions in temperatures of -5.0 to 60.0 degrees C/23.0 to 140.0 degrees F (+ or - 0.1 degrees C / 0.1 degrees F), and has a range of -2.00 to 16.00 pH (+ or - 0.05) with a resolution of 0.01 pH. The meter can be calibrated at one or two points for pH with auto-buffer recognition, and against five memorized buffer values. For ORP (Oxidation Reduction Potential) readings, the tester has a range of + or - 1000mV (+ or - 2) with a resolution of 1mV and automatic factory set calibration. Dimensions are 163 x 40 x 26 mm (6.4 x 1.6 x 1.0"), with weight 100 g (3.5 oz.).

pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.
