Premium quality, high accuracy pH buffer for calibrating pH meters.

Premium quality, high accuracy conductivity calibration solution.

This palm-sized pH meter with cabled electrode can measure pH, voltage potential difference (mV) and temperature.

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

Reads either pH (in 0.01 resolution) or mV in large digits, with time, date, and temperature (in °C or °F) shown simultaneously on the lower display.

With a long-lasting design, this 3-in-1 tester is a smart choice for student experiments in both the classroom and field applications.

Reads pH, ORP (oxygen reduction potential), mV, conductivity, TDS (total dissolved solids), salinity and temperature.

Rugged, field-ready meter for multi-parameter water quality testing with GPS logging.

Accurate. Waterproof. No more switching between meters for your routine measurements with the HI98130 pH and conductivity tester.

Versatile digital meter for pH, conductivity, and dissolved oxygen measurement in one device.

This tester is a reliable, waterproof tester that ensures quick and easy measurements of both pH and ORP. This accurate pH and ORP tester features 0.01 pH resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device. No more switching between meters for your routine measurements.

This laboratory pH meter delivers precision while offering simplicity and versatility in a sleek design.
