Digital residual chlorine electrode BH5530D

Features

• Power and output isolation design to ensure electrical safety.
• Power supply and communication chip built-in protection circuit, strong anti-interference ability.
• With comprehensive protection circuit design, it can work reliably without additional isolation equipment.
• The circuit is built inside the electrode for better environmental tolerance and easier installation and operation.
• RS-485 transmission interface, MODBUS-RTU communication protocol, two-way communication, can receive remote commands.
• The communication protocol is simple and practical, and it is extremely convenient to use.
• Output more electrode diagnostic information, more intelligent.
• Internal integrated memory, the stored calibration and setting information can still be remembered after the power is turned off.
• Using 316 stainless steel shell, platinum sensor, three-electrode principle.
• PG13.5 thread for easy on-site installation.
• 2 power cables, 2 RS-485 signal cables.
• The fluctuation range of the 12-24V DC power supply is 10%, and the 2000V isolation.
