Usage: The meters are capable of measuring up to 8 water quality parameters, including pH, ORP, ISE, conductivity, TDS, salinity, resistivity, DO and temperature.

Features: Built-in real-time clock stamps stored data; USB communication interface. Adjustable temperature coefficient, cell constant, TDS coefficient, salinity and barometric pressure compensation.
