This pH tester is an easy-to-use pH water tester that makes monitoring water quality simple. This accurate pH tester features 0.1 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device.

The electronic salt tester measures the Sodium Chloride level in salt water pools with a range from 0 to 9,999 ppm. TDS is measured from 0 to 9,999 ppm and Temperature from 32.0° to 149°F.

All-in-one handheld tester for monitoring pH, nutrients, and water quality in hydroponic and agricultural systems.

The double junction electrode is ideal for dirty water, heavy metals, sulfides, tris buffers, and organics. The tester also features a pH and temperature readout toggle, automatic temperature compensation, and a replaceable sensor.

Functional and accurate, this meter is capable of testing 12 different water quality parameters using pH, EC, and optical DO sensors. Transfer data to a smart device for review or sharing with the integrated Bluetooth connection and Hanna Lab App.

This multiparameter meter is a rugged, waterproof multiparameter meter. This meter's multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, and temperature. The multiparameter probe transmits readings digitally to the meter, where data points can be displayed and logged. The complete water quality meter is simple to setup.

Keep your DO meter performing like new. Ensure accurate, reliable results for every classroom experiment.
