Residual chlorine transmitter
The residual chlorine transmitter adopts an original imported residual chlorine sensor, which has the characteristics of no calibration, no maintenance, high accuracy, small size, and low power consumption. The residual chlorine sensor has the outstanding advantage of replaceable probes, which can greatly reduce the cost of long-term use. The transmitter outputs a 4-20mA standard signal for residual chlorine, which can be connected to various regulators such as two position regulators, time proportional regulators, nonlinear regulators, and classic PID regulators according to customer needs, and combined into various residual chlorine control systems. This modular design concept, which is different from similar instruments, can greatly reduce the user's one-time investment, with high cost-effectiveness, wide applicability, and good compatibility.
This product is widely used in industries such as drinking water treatment plants, drinking water distribution networks, swimming pools, etc. for continuous monitoring of residual chlorine content in aqueous solutions.
