Real-time air quality/CO2 detection with flexible connectivity for both new and existing building networks.
Note: All Tongdy monitors and controls ship direct from the factory. Please allow 10-15 business days for shipping and handling.
It features an optional temperature and humidity sensor, with an OLED display providing real-time data. Equipped with one or two analog outputs configurable for linear or PID control, it monitors CO2 levels alone or alongside temperature. A relay output with dual control modes and a Modbus RS485 interface allow seamless integration with BAS or HVAC systems. An audible buzzer and relay-triggered alarm enhance safety by alerting and managing connected devices effectively.
