This continuous TDS monitor features an easy to use, quick to set up design for real-time Total Dissolved Solids readings.

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.

This 3-in-1 continuous pH/TDS/Temp monitor is easy to use and has a full display that allows users to have real-time readings of pH, Total Dissolved Solids, and Temperature.

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

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

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

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

Advanced portable system for dissolved oxygen, pH, and conductivity testing in field conditions.

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.
