This product monitors the CO₂ concentration in harsh and polluted applications such as agriculture and livestock barns.

This handheld device displays CO, CO₂, air temperature, rh, dew point, and wet bulb temperature measurements.

Users can choose from 25 different IAQ, green building, industrial hygiene, and HVAC parameters, including total volatile organic compounds (TVOCs), CO₂, CO, ozone, nitrogen dioxide, ammonia, sulfur dioxide, chlorine, hydrogen sulfide, humidity, temperature, etc.

The unit can measure/record for several days or even months. The acquired data is stored to the tester’s 2 Gb SD card and can be transferred to a computer for data readout and further evaluation.

When the system identifies a potential issue, it immediately alerts up to eight people with custom phone calls, allowing personnel to quickly address the situation.

The DAFA can monitor radon mitigation systems by detecting a loss of airflow in the pipe and providing a signal to the homeowners if the fan has stopped operating.
