Portable thermo-hygrometers for a on-site diagnosis

Air quality diagnosis integrates humidity and air temperature measurement, dew point measurement…, thanks to a portable thermo-hygrometer.

Instant humidity measure

Capacitive humidity sensor

The capacitive humidity probes convert the level of absorbed electrical capacity in relative humidity rate (%RH). The Quickstick humidity probe measures humidity from 0 to 100% RH by this method. It is used with the Humitest MMS or Humitest Hygro L thermo-hygrometer (examples of application: buildings diagnosis, follow up of post disaster dryout -flooding, damage by water-, indoor air quality diagnosis...).

Resistive humidity sensor

The resistive humidity probes use electrical resistance to convert measurement into relative humidity rate (%RH). By this principle, the Hygrostick probes don’t only measure humidity, but also the Equilibrium Relative Humidity of any materials. Theses humidity sensors can be inserted in a humidity boxe or humidity sleeve, thus creating a sealed air pocket on the surface of a substrate (slab, screed, wall…). They are used together with Humitest MMS or Hygro L for non destructive measurements.

Temperature sensor

Thermistors, these sensors measure temperature (°C/°F) from the resistance variation. The Quickstick and Hygrostick humidity probes measure ambient temperature between 0 and 50°C with this method.
As for the surface temperature sensor of the Humitest Hygro L Plus and the Humitest MMS thermo-hygrometers, it allows direct display of the difference between surface temperature and dew point.
To measure changing environments, the Humitest Psyclone thermo-hygrometer gives access to different settings (minimum, maximum, mean…) and automatic psychrometric calculations: surface temperature, dew point, wet bulb, mixing ratio.
