Intro:

SPCO2 detector/Indicator is used to monitor and alarm CO2
level and room temperature.
Relative humidity detection and display can be as an option. Other options can be provided to users: RS485
communication interface with independent address; one dry contact output to control a ventilation device.
Especial design for schools, kindergartens, office buildings, conference rooms, rest rooms as well as
other public places

Features:

1.Real-time detecting and display CO2 level during 0ppm to 20,000ppm CO2 range; Also detecting room temperature from 5 to 45°C.

2.Optional real-time humidity from 5%RH to 95%RH .

3.NDIR CO2 sensor technology of infrared self diffusion, 15 years lifetime.

4. Self Calibration Algorithm makes it in using without calibration amending.

5.The three measured CO2 ranges for 3-LED indicator lights selectable by end users.

6.LED’s brightness adjustment.

7.Optional 1X dry contact output or one 0~10VDC output to control a ventilation device.

8.Easy preset CO2 level for buzzer alert (optional) .

9.Optional RS485 interface to connect to a PC or another system (optional).
