VCP-DXC120
Product Description
Calibratable USB Carbon dioxide (CO2) gas sensor – with VCP mode
The DXC120 is a small USB-connected gas sensor for monitoring the indoor level of carbone dioxide (CO2). Built around an advanced NDIR CO2 sensor, the DXC120 supports a self-calibration mechanism that automatically compensates for long-term drift. In addition to this mechanism, this device can manually be calibrated with fresh air in one click via our free DAQ software.
The DXC120 has been specifically designed to meet the needs of monitoring CO2 levels in living places such as home, workplace, or other environments with moderate conditions. For advanced detection of CO2 levels in more hostile environments, please refer to our DXC220 unit.

Calibration
Every DXC120 unit is delivered with a supported instant calibration mechanism to fresh air, that is easily accessible in one click via the latest versions of our free data logging software. In addition to this mechanism, these devices have a built-in self-calibration mechanism that can be activated and disactivated at will as easily via our Dracal DAQ software. The mechanism is based on the lowest CO2 measurement recorded over a period of 7 to 9 days in order to restore its minimum reference value to 450 ppm.
