Testo, 0632 1552, CO2 Probe Including Temperature and Humidity Sensor, Fixed CableUse the probe to check the indoor climate, for example in offices, production areas or storage facilities. To ensure accurate measurement results, air density compensation is carried out via the integrated absolute pressure measurement. Particularly useful: store individual readings directly in the measuring instrument by pressing the button on the probe. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. You can use these trends to evaluate changes in the indoor air quality.Space-saving: more applications, less equipmentEndlessly versatile: a universal handle can be connected to all probe heads – so you can master more applications using less equipment and save space. Order the Bluetooth handle to make it more convenient to carry out your measurement and guarantee less cable clutter in the case. This transmits the readings to the measuring instrument from a distance of up to 20 metres. If the sensors (CO2, humidity, temperature) need to be replaced in the distant future, you can change the probe head.Intelligent calibration conceptYou will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration – so the measuring instrument remains in continuous use.Areas of application for the CO2 probeUse the CO2 probe including temperature and humidity sensor to check the indoor climate (indoor air quality), e.g. in offices, production areas or storage facilities. The CO2 concentration is a primary indicator of indoor air quality. Poor air quality due to excessive CO2 concentration results in tiredness and lack of concentration, and can even cause illnesses. The CO2 concentration should therefore not normally exceed 1,000 ppm.Features:Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of CO2 concentration, humidity and air temperature in indoor areasPrecise: calculation of wet bulb temperature, dew point and absolute humidityConvenient: a universal handle can easily be connected to other probe headsIntelligent calibration conceptCO2 probe including temperature and humidity sensor (consisting of CO2 probe head and cable handle (cable length 1.4 m); 4 x AA batteries, table stand and calibration protocol.
