Product Description

Use the probe to quickly check the indoor climate, for example in offices, production areas or in warehouses. As well as temperature, humidity and absolute pressure, it also measures the carbon dioxide concentration (CO2).

The CO2 concentration is a primary indicator of indoor air quality. Poor air quality due to excessive concentrations of CO2 can cause tiredness, lack of concentration and even illness. Therefore the CO2 concentration should normally not exceed 1000 ppm.

Intelligent calibration concept

The probe offers maximum digital measurement reliability. The digital probe allows readings to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. The probe can be returned on its own (without the measuring instrument) for calibration. Calculating the determined calibration data in the probe generates a zero-error display. 

Delivery Scope

Indoor air quality probe including desktop tripod.
Note: you need a plug-in head cable (0430 0100) for this probe.
