Real-time detection with user-replaceable sensors, flexible outputs, and seamless integration into building management and ventilation systems.
Note: All Tongdy monitors and controls ship direct from the factory. Please allow 10-15 business days for shipping and handling.
This CO Monitor delivers real-time carbon monoxide detection with current readings and a one-hour average. Featuring a long-life Japanese sensor that is easily replaceable by the user, along with zero-point calibration, it ensures accuracy and low maintenance. Outputs include 0–10V / 4–20mA signals, two relays, and optional RS485 Modbus RTU, with a configurable buzzer alarm for added safety. Compact, reliable, and easy to service, it’s ideal for building management and ventilation control systems.
