First, an overview 
 XHCL-7135 intelligent controller is a microprocessor chlorine-based chlorine, chlorine dioxide generators, ozone-line measurement and control instrument. Constant voltage of advanced sensors, high sensitivity, fast response signal, the measurement accuracy, stable performance, easy maintenance. The end of water pipe network in the city, steel mills, chemical companies and other units of sewage treatment systems under the conditions of less than 0.1ppm of chlorine have good performance. 
 The detector can be connected to the Italian company match magnetic SZ283 chlorine sensor for magnetic piece to replace imported Italian company CL7685, CL3630, CL7635 types of monitoring device, is the chlorine dioxide equipment manufacturers to reduce costs and improve competitiveness of high-quality accessory products . 
 Second, the features 
 ? measurements show that chlorine levels, you can adjust the measurement range (0-2ppm ,0-20ppm). 
 ? According to the sampling of residual chlorine value retransmission output 4-20mA current, and can modify the output current range. 
 ? There Road Relay output: maximum output, minimum output. 
 ? with RS485 communication function, the national standard MODBUS-RTU communication protocol. 
 ? chlorine automatic control (control current output, pulse output control) 
 Typical applications 
 1, chlorine generator, online test. 
 2, automatic control of chlorine dioxide detection 
 3, ozone-line detection 
 4, swimming pool disinfectant chlorine test 
 5, treatment of residual chlorine test online 
 6, disinfectant dosing line (automatic control)
