The Hanna Instruments HI 98103B is a hand-held pH meter with manual two-point calibration, a replaceable electrode, and an LCD screen. The meter provides readings from 0.00 to 14.00 pH (+ or - 0.2), with a resolution of 0.01 pH. It is designed for beer and beverage making, but can be used for other applications; it is an alternative to litmus paper.

The HI 98103B operates from 0 to 50 degrees C (32 to 122 degrees F) with maximum relative humidity (RH) of 95%. The HI 1270 electrode is replaceable to prolong the life of the meter. Two 1.5V batteries are included, and provide approximately 3,000 hours of continuous use. The meter measures 66 x 50 x 25 mm/2.6 x 2.0 x 1.0 inches (H x W x D) and weighs 50 g (1.8 oz.). (H is the vertical distance from lowest to highest point; W is the horizontal distance from left to right; D is the horizontal distance from front to back.) Buffer solutions (4.01, 7.01, and 10.01 pH), storage solution (HI 70300M), and replacement electrode (HI 1270) are sold separately.

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

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards.
