Introduction                                                                                                                    

Industrial PH Meter is the intelligent upgrade product of industrial ph testing instrument. It could measure and control ph value of wastewater continuously, the ph meter is applicable for municipal wastewater treatment, chemistry, printing and dyeing, paper, medicine, plating and environmental production etc.

In accordance with the environment and characteristics of water industry, as well as the international power supply standard, considering the electricity design in special environment, the ph meter could be supplied with power 220V AC, and safe low voltage 24V AC,24V DC for selection.

Main Characteristics:                                                                                                      

²  English (and chinese) language display

²  Measure pH/ORP, high/low limit control, current output, digital communication

²  It could be set automatic temperature compensation(ATC) or manual temperature compensation

²  pH high limit alarm, pH low limit alarm, double relay, alarm delay could be adjust;

²  Instrument mode isolated transmitting port, max circle resistance bigger than 300Ω;

²  Sound alarm function could be set;

²  Backlight of LCD could select power saving mode, timing automatic off;

²  High performance CPU, good electromagnetic compatibility;

²  Password management avoid non-professional person operation;
