Residual chlorine online monitor (constant pressure method)

Product Introduction:

The residual chlorine online monitor (constant pressure method) has a three-electrode structure, namely CE (counter electrode), WE (working electrode), and RE (reference electrode). The participating electrodes can be used to maintain a constant potential difference between the working electrode and the solution, making the measurement environment more stable and eliminating the need for frequent corrections. The constant pressure residual chlorine analyzer has the characteristics of free calibration, maintenance-free, high accuracy, small size, and low power consumption. The display instrument has slope correction, zero point correction, real-time display of measured values, and automatic temperature compensation and manual pH value compensation functions, which convert the electrode signal compensation calculation into a more accurate residual chlorine signal.

Product features:

1. LCD screen Chinese interface display, simpler and more convenient operation;

2. Adopt high-precision 24-bit ADC signal acquisition and anti-interference circuit, higher accuracy and more stable;

3. Photoelectric isolation 4~20mA current output, RS-485/RS2-232 communication interface;

4. Optional upper computer online acquisition software for data acquisition and analysis;

5. The system supports one-key calibration of standard liquid, built-in watchdog function, power-off protection greater than 10 years;

6. Dual relay upper and lower limit alarm output;

7. The sensor has built-in temperature compensation, which can correct the influence of temperature on residual chlorine value;

8. Support customized special function requirements;
