Frequently Bought Together
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.).

TIP: If you haven't used it in a long time...just soak it in some 2.5 acid water overnight.
TIP: If doing demo's and it seems to not be adjusting to orp fast enough...run some 11.5 and 2.5 in two cups. Then put meter in one cup then the other for 20 secs or so each, keep going back and forth till it starts registering orp faster. Once satisfied put a little 2.5 in the cap and close...no you're ready! I do this before EVERY demo...it helps the unit register a lot faster.
