"hobo data logger"

Units have instant-response probe and solid-state thermistor for quick, precise readings.

This pH tester is ideal for wastewater, water quality and environmental applications. Compact, water resistant (IP67) instrument fits into the palm of your hand.

Lightweight, Versatile Unit

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.

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

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 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.
