"hobo data logger"

Portable multi-parameter meter for measuring pH, conductivity, and dissolved solids in agricultural and hydroponic systems.

Measure oxygen concentration and percent saturation

Designed for today's crowded laboratory benchtops!

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.

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

Versatile and portable meters for wherever your lessons take you.

Sleek, multipurpose pH meter with smart electrode recognition and easy calibration.

This laboratory benchtop dissolved oxygen meter delivers precision while offering simplicity and versatility in a sleek design. Use your multiparameter meter as a portable, benchtop meter, or mount it on the wall to save space.

The DO600-K is a convenient kit which adds versatility for measuring dissolved oxygen in laboratories or out in the field with a 16' (5 m) extension cable and probe weight guard for taking easy measurements in tanks or streams.

Simple to use benchtop meter for easily measuring pH and ORP.

Highly reliable and user-friendly pH benchtop meter for standard laboratory applications.

An advanced, research-grade benchtop pH meter offering accurate, repeatable results.

Simple-to-use benchtop meter designed to easily measure conductivity, TDS and salinity.

Highly reliable conductivity/TDS/salinity/resistivity benchtop meter for standard laboratory applications.

Easy-to-use and accurate multi-parameter benchtop meter.

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.
