  • Description

    Protimeter Hygromaster L Thermohygrometer

    The Protimeter Hygromaster L Thermohygrometer is capable of measuring air temperature and relative humidity, which then allows it to calculate psychometric values such as dew point and specific humidity. This is ideal for assessing condensation conditions in buildings.

    With a Quickstick sensor, the meter can measure humidity from 1% to 100% whilst with a Hygrostick sensor, the range goes from 30% to 98% with greater accuracy and is more suited to measuring conditions in concrete flooring slabs and high-humidity environments. Simply use the drop-down menu above to select your sensor. The air temperature range goes from 0˚C to 50˚C with both sensors.

    The vibrant colour display on the Protimeter Hygromaster L clearly shows measured and calculated values – up to three can be shown simultaneously – as well as the intuitive menus that are used to operate the thermohygrometer. It has multiple applications in damage restoration, surveying, concrete moisture measurement and the HVAC sector.

    The Protimeter Hygromaster L comes supplied with a humidity sensor, wrist strap and carry pouch. It is covered by a 24-month warranty.
