The Hanna Instruments HI 98108 is a compact pH tester that has Automatic Temperature Compensation (ATC), manual one- or two-point calibration, a single-level LCD screen, an extendable cloth junction, and a protective cap. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications. The single-line LCD screen of this meter shows the current measurement. The meter has automatic temperature compensation from 0 to 50 degrees C for accurate readings in fluctuating temperatures. The meter has manual one- or two-point calibration through a trimmer on the side. A renewable cloth junction can be pulled out approximately 20 times to expose a fresh section and extend the life of the meter. A protective cap keeps the sensor moist when stored upright. Four 1.5V AA batteries provide approximately 200 hours of use. The meter also comes with a calibration screwdriver and instructions.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.
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) standard 9001.
