Amprobe CO2-200 - Wall Mounted Carbon Dioxide Meter

The Amprobe CO2-200 measures CO2 level, air temperature, dew point, wet bulb temperature and humidity and is an ideal instrument for indoor air quality (IAQ) diagnosis.

Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals and hotels. It is also suggested in regulations of industrial hygiene in some countries.

With an NDIR (non-dispersive infrared) sensor used, this CO2 meter is stable in long term monitoring. And the built-in relay for alarm output is especially useful in ventilation control and HVAC system performance verification.
 

Alarm Output

The meter features visible and audible alarm to give warnings when CO2 concentration exceeds the limit. Users can set up 2 limits: An upper limit for alarm threshold that requires air conditioning and a lower limit to stop the alarm. (See P1.0 in setup for setting alarm limits).

It emits beeps (approximately 80dB) with blinking LED when CO2 level goes over the upper limit. Beeps can be stopped by pressing any key or automatically stops when CO2 reading falls below lower limit. If the beeper is temporarily shut, it will sound again when readings fall below lower limit and then go over the upper limit again, or users press “RESET” for more than 1 second to activate it. LED alarm keeps blinking when beeps are manually shut. It stops only when readings fall under the lower limit.

The meter is designed with a relay to send output for further connection. When CO2 readings go over the upper limit and cause alarming. The relay picks up automatically and sends output. It can be connected to a ventilation system or activator for conditioning the air quality. The relay will drop out when CO2 readings fall under the lower limit.
