"Multifactor Water Test Kits"

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

A simple visual test kit that lets students quickly check for the presence of common pesticide residues in water or on produce without needing lab equipment.

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

Rugged and compact, the redesigned HOBO USB Micro Station is a weatherproof data logger for multi-channel monitoring of microclimates.

Easy way to test water for multiple factors.

Measures and records conductivity and temperature in streams, lakes and other freshwater sources. Recommended for monitoring aquifers for saltwater intrusion and road and agricultural run-off.

The Free and Total Chlorine Photometer combines accuracy and ease of use in a simple, portable design. The advanced optical system provides lab-quality accuracy while its user-friendly design is easy for any user making it the perfect photometer for your water quality testing needs. This meter measures free and total chlorine in water samples from 0.00 - 5.00 mg/L (ppm).

A cost-effective data logger for measuring salinity, conductivity and temperature in saltwater environments with relatively small changes in salinity (±5000 μS/cm).

Monitor energy and industrial equipment with this 15 channel data logger to quickly detect and address issues relating to HVAC, machinery and other systems.

This multiparameter meter is a waterproof portable logging multiparameter meter. The microprocessor based multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, turbidity, and temperature. The complete system is simple to setup and easy to use.
