CX-401 measures: pH, redox potential (mV), conductivity, resistivity, salinity in KCl or NaCl, TDS, dissolved oxygen in % of saturation or in mg/l, oxygen in air in %, atmospheric pressure and temperature.

The function is chosen with the “FUNCTION” button. It is possible to choose a version with GXZ-3tk multifunction (multi-parameter) head with electrodes for simultaneous measurement of three different functions (e.g. pH, conductivity and oxygen dissolved in water with temperature) or version with single electrodes. The models have different connectors.

Characteristic features:

• CX-401 may be used for laboratory and field measurements.
• This small-size meter includes all functions of pH meters, conductivity meters and oxygen meters of the 401 series.
• The meter is equipped with easy to read backlight LCD display with brightness
  control, which enables observation of the chosen function and temperature results.
• “HOLD” function to freeze the result on the display.
• Signalisation of the result stabilisation with “READY” symbol and asound.
• Possibility of sending a calibration report to a PC – up to 10 last calibrations.
• Unification of the operating procedures in all measuring functions makes working trouble-free.
• Low weight and small size make working in the field easier.
•  Waterproof housing (IP-66) enables working in difficult conditions.
