Water quality/conductivity Measuring Instrument
Characteristics of conductivity/TDS/salinity/resistivity mode:
² High precision conductivity/dissolved oxygen meter, equipped with a large backlit LCD display screen.
² 1 to 5 point calibration, automatically identifying conductivity standard solution.
² Optional electrode constant (K=0.1/10), reference temperature (20/25 ° C), TDS conversion coefficient, linear and pure water compensation, seawater and practical salinity measurement mode.
Dissolved oxygen mode characteristics:
² 1 or 2 point calibration, using air saturated water or zero oxygen solution.
² Salinity and atmospheric pressure compensation to eliminate measurement errors.
