Hanna Instruments HI 98107 pHep pH Tester, with +/-0.1 Accuracy

The HI 98107 pHep pH Tester is a portable pH meter with a replaceable electrode and a non-clogging, replenishable fiber junction.

Featuring a large easy-to-read LCD screen, the tester provides fast and accurate pH readings in a rugged and ergonomically designed casing. The HI 98107 has a replaceable electrode and renewable reference junction, which helps prolong the life of this tester. With the replenishable junction, simply pull 1 to 2mm (1/8'') of the junction out with tweezers to recondition the pH electrode. This procedure can be repeated up to 15 times, before the whole fiber is removed.

The HI 98107 tester functions in temperatures of 0 to 50 degrees C (32 to 122 degrees F), and has a range of pH 0.0 to 14.0 (+ or - 0.1 pH) with a resolution of 0.1 pH. It is calibrated manually to 2 points. The HI98107 is an updated version of the HI96107 (pHep) pH meter. The dimensions are 175 x 41 x 23 mm (6.9 x 1.6 x 0.9") and the weight is 95g (3.4 oz.).

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