Store Up to 15 Readings

Lightweight, Versatile Unit

This convenient device measures dissolved oxygen concentration, saturation, and temperature - all in one!

Flat electrode surface allows pH readings in liquid flms, semi-solids, and solids.

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

High-precision benchtop pH and ORP meter with advanced data logging and diagnostics.

Sleek, versatile pH and ORP meter designed for laboratory, classroom, or field use.

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.

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.

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.

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

Designed for today's crowded laboratory benchtops!

This wireless field pH meter has a durable PEI body and spherical sensing bulb. All readings are transmitted directly to your Apple or Android device.

This pH meter is seriously thin and light with lab grade functionality packed into a tablet design. With simple operation and advanced features, edge pH easily outperforms all other portables and benchtops in its class. Advanced pH electrode diagnostics ensure worry-free measurements. Use this pH meter as a portable, benchtop meter, or mount it on the wall to save space.

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.

The HALO2 Wireless General Use pH Tester has a refillable glass body and spherical glass sensing bulb made for users that prefer a low-maintenance laboratory-grade pH electrode.
