The hygrometer is used to monitor the concentration of carbon monoxide in the ambient air and detects elevated CO levels at an early stage. The hygrometer enables continuous monitoring of air quality and supports the rapid detection of potentially hazardous carbon monoxide concentrations.

The hygrometer features an electrochemical CO sensor with a measuring range of 0 ... 999 ppm CO, an accuracy of ±5 ppm and reliable detection of carbon monoxide concentration. In addition to CO, temperature from −10 ... 50°C / 14°F ... 122°F and humidity from 0 ... 95% RH are also measured. Operation is intuitive via three buttons for switching on/off, alarm function and display brightness. Measurement is carried out at a measuring interval of 2 seconds, while the sensor warm-up time is approximately 35 seconds. The alarm range is 51 ... 999 ppm and is indicated by an audible and visual alarm display. The measured values are shown on a digital display. Power is supplied by an integrated lithium-ion rechargeable battery. The robust design with wrist strap and wall mounting option allows flexible use in a variety of environments.

The hygrometer is particularly suitable for anyone who requires reliable monitoring of indoor air quality, for example in homes, offices, workshops, garages or for mobile applications.
