Product Description

 Product Features:

Temperature, pH, conductivity, dissolved oxygen and turbidity can be tested simultaneously.
 

1.Adopting large dot-matrix LCD, it can display residual chlorine, pH and temperature values at the same time;

2. Support automatic pH compensation and automatic temperature compensation for residual chlorine;

3. Support automatic saving of measurement results, up to 2000 groups of data can be saved;

4.Support to set alarm upper and lower limits and return difference for residual chlorine or pH measurement values;

5.Supports power failure protection function;

6.With two (4~20) mA DC isolated signal outputs, corresponding to the data output of residual chlorine or pH measurement value, the output lower limit and output upper limit can be set arbitrarily;

7.With RS-232 or RS-485 digital interface (2 choose 1), Modbus communication protocol.
