"Multiparameter Meters"

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.

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.

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

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.

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