PH+EC+DO Meter เครื่องวัด PH+EC+DO

EC900 9-in-1

Measures Dissolved Oxygen concentration/saturation,
pH, mV, Conductivity, TDS, Salinity, Resistivity and
Temperature
Automatic salinity compensation and manual barometric
pressure compensation for DO measurements
One button pH calibration (4, 7, and 10pH)
Choice of 3 point pH calibration for better accuracy
One point conductivity calibration - automatically
recognizes 8 calibration solutions from USA, Europe and
China series
Automatic Temperature Compensation (non-linear
compensation for purified water <10 S/cm to improve
measuring accuracy)
Memory stores up to 400 readings with series number,
measured value and temperature
Large blue backlit dual LCD display
