Testermeter-F2000TSM Carbon Dioxide Sensor NDIR
overview
| This is a low-cost CO2 transmitter designed for applications in HVAC, ventilation systems, offices, schools, and other public places. NDIR CO2 sensor inside with Self-Calibration and up to 15 years lifetime. One analog output of 0~10VDC/4~20mA and six LCD lights for six CO2 ranges within six CO2 ranges make it unique. RS485 communication interface has 15KV anti-static protection, and its Modbus RTU can connect any BAS or HVAC systems. |
Features
| Real-time detecting CO2 level. NDIR infrared CO2 module inside with four CO2 detection range selectable. CO2 sensor has Self-Calibration Algorithm and 15 years lifetime Wall-mounting Providing one analog output with voltage or current selectable 0~10VDC/4~20mA selectable easily via jumpers Special “L” series with 6 lights indicates CO2 level and makes CO2 level show clearly. Design for HVAC, ventilation systems, offices, or other public places. Modbus RS485 communication interface optional: 15KV antistatic protection, independent address setting CE-Approval |
