Instrument Features

(1) By adopting high-precision AD conversion and single-chip microcomputer processing technology, it can complete various functions such as conductivity measurement, temperature measurement, temperature automatic compensation, range automatic conversion, and instrument self-test
(2) Simultaneous display of multiple parameters: conductivity and temperature are displayed simultaneously on the same screen. Adopting high brightness LED display module, the main display shows the conductivity value with a red 10 × 10mm digital tube, which is eye-catching and visible from a long distance
(3) Strong anti-interference ability: The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and achieves original transmission. Has good electromagnetic compatibility
(4) Waterproof and dustproof design: anti slip rating IP65, suitable for outdoor use
(5) 25 ℃ Conversion: The conductivity value obtained at the current temperature is converted to 25 ℃, achieving the actual conductivity value at 25 ℃, which is particularly suitable for measuring various water qualities in power plants.
(6) Automatic range conversion: Achieve automatic range conversion within the measurement range covered by the electrode.
(7) Communication interface: Can be easily connected to a computer for neck side and communication
