DZS-706 multi-parameter water quality meter

 Instrument functions:

u        It can measure pX/pH, ORP, conductivity, TDS, salinity, Resistivity, dissolved oxygen, saturation and temperature.

u        It adopts LCD display and Chinese operation interface.

u        It has manual/automatic temperature compensation.

u        It provides zero oxygen and full scale calibration.

u        When the meter measures conductivity, it can switch frequency automatically to guarantee measuring accuracy.

u        It has power failure protection functions.
