  • Audible and visible alarms plus relay output trigger ventilation control

Purpose and audience

The Amprobe CO2-200 is a wall-mounted carbon dioxide meter designed for indoor air quality monitoring in offices, classrooms, factories, hospitals and hotels. It measures CO2 concentration from 380 to 2000 ppm, along with temperature, relative humidity, dew point and wet bulb temperature, giving facility managers a single instrument for comprehensive IAQ assessment.

Upgrade path

This meter replaces basic CO2 indicators that lack data logging or alarm outputs, and it upgrades from spot-check devices by providing continuous monitoring with weighted average statistics such as TWA and STEL. The jump is worthwhile when building codes or occupational health guidelines require documented CO2 trends, audible and visible alarms, or a relay output for direct ventilation control integration.

Build integration

The unit mounts on a wall and connects its alarm output to HVAC or building management systems for automated ventilation responses. Its stable NDIR sensor supports long-term deployment without frequent recalibration, freeing maintenance staff from repeated manual checks while delivering the triple-display readout needed for real-time verification of air quality parameters.

Questions about this item

Does the Amprobe CO2-200 include hardware for wall mounting?

The meter is described as a wall-mounted carbon dioxide meter, so it is designed for fixed installation on a vertical surface.

How is the alarm output wired for ventilation control?

The built-in relay provides an alarm output that can be connected to a ventilation or HVAC system for automated control when CO2 limits are exceeded.

Will the NDIR sensor require periodic calibration or replacement?

The non-dispersive infrared sensor is noted as stable for long-term monitoring, reducing the frequency of calibration compared with other sensor types.
