Easy to carry, simple to operate and sufficient for most field pH tests.

Lightweight, Versatile Unit

This spare pH sensor makes electrode replacement quick and easy. The spare pH sensor is designed as an easy-fit cartridge that locks into place, featuring two o-rings to maintain a watertight seal. With no pins to line up or that can break, this sensor is ideal for quick replacements.

This pH electrode is a plastic body, double junction, gel filled pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design.

Multi-parameter meters engineered for student use in real world testing environments.

High-quality pH 10 calibration buffer for standardizing meters in basic solutions.

Gentle cleaning solution designed to remove buildup and maintain electrode accuracy.

Top Seller! Designed to bring simplicity to pH testing during the any process, the HI98100 Hanna Checker® Plus pH Tester is designed for direct measurement. A replaceable electrode extends the life of your digital pH tester.

This tester is an advanced, waterproof conductivity and TDS (ppm) tester for quick and easy measurements while on the go. This lightweight, waterproof conductivity tester offers accurate conductivity (0 to 3999 µs/cm), TDS (0 to 2000 ppm), and temperature measurements in a single, portable, pocket device. No more switching between meters for your routine measurements.

This general purpose cleaning solution can be used for a variety of applications. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction.
