Product description
The Hanna Instruments HI 98111 is a compact pH tester with a narrow probe for use in small samples or test tubes, and has Automatic Temperature Compensation (ATC), manual two-point calibration, a single-line LCD screen, a replaceable pre-amplified electrode, and buffer solution. 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 pH measurement or the current temperature. The meter has ATC and manual two-point calibration through trimmers on the front. The interchangeable 90mm (3.5") electrode houses the pH sensor, reference system, temperature sensor, and the amplifier module. Three 1.5V AA batteries provide approximately 100 hours of use. The meter also comes with buffer solution sachets, a calibration screwdriver, a carrying case, 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.
