The portable work safety device FHM 10 is used to measure formaldehyde concentrations and can save the measured values. There are threads on the hand-held device and on the probe, which makes it possible to attach it to a tripod, in addition to its mobile use. When using the work safety device with a tripod, long-term measurements can be carried out. When switched on, the device carries out a self-calibration process, followed by the measurement. In addition to formaldehyde (HCHO), the work protection device also measures the temperature °C and °F, as well as the relative air humidity. During the measurement, the measuring units °C and °F can be changed. The work safety device FHM 10 does not only offer a HOLD function but also a peak value measurement. After measuring with the work protection device, you can transfer the data to a computer via USB for further evaluation.
