HT-86 carbon dioxide detection controller
HT-86 carbon dioxide detection controller adopts infrared gas detection and sensing unit, with high measurement accuracy, fast response speed and long service life. It can monitor the concentration of CO2 gas in the air environment in real time and display the value through the LCD screen. The fresh air system can be automatically controlled to turn on and off according to the change of CO2 concentration in the environment, and the alarm value (turn on the control device) and the alarm release value (turn off the control device) can be set freely.
The instrument comes standard with a passive contact relay switch signal, which can be optionally output Modbus RS485 bus digital signal or 4-20mA analog current signal at the same time.
The instrument is wall-mounted and wired, which is widely used in indoor construction projects.
◆It integrates detection and control functions, easy to use, stable and reliable technology;
◆ The CO2 sensor adopts NDIR infrared sensing technology, and the structure adopts the aluminum tube pass-through structure commonly used in analytical instruments, which ensures the excellent measurement performance of the product, and has the characteristics of more accurate measurement, faster response and more stable performance.
◆ The product shell size is 86×86×27mm, and the terminal block wiring box is 86 boxes, which is simple and convenient to install;
◆ Output signal: 1. A passive contact relay switch signal (standard) 2. Modbus RS485 digital signal (optional); 3. 4-20mA analog current signal (optional);
◆ Self-calibration function is turned on, and manual calibration in fresh air is supported.
