"hobo data logger"

Wireless soil pH tester connects to smart devices for real time monitoring and data collection in agricultural applications.

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

Versatile and portable meters for wherever your lessons take you.

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.

This multiparametrer tester is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off.

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

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

Measure pH across a range of food products with wireless testers designed for milk, cheese, and meat analysis in food science and agricultural studies.

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