Thermo-Hygrometer PN

PN Hygrometer has wider humidity range and shorter response time.

Thermo-Hygrometer PN indicates:
– relative humidity,
– ambient temperature

+

Controlled ambient conditions
protect wood products
from shrinking and cupping.

Thermo-Hygrometer PN

“Air humidity” affects wood. As RH goes up, wood absorbs moisture and swells. As RH goes down, wood looses moisture and shrinks. Once wood has reached its equilibrium moisture content (EMC), it will be stable and neither absorb nor loose moisture.

“Air humidity” affects our environment and our health. Mold is the dreaded word. Mold destroys materials and makes humans sick. Mold growth can be prevented, if relative humidity stays within a safe range.

Hygrometer PN is for high and low relative humidity and on-the-job fast readings. Pen shape allows measuring hard to reach areas.

Hygrometer PN is the right choice for cold climate zones, where relative humidity drops as low as 5% in the winter.  It is also recommended for inspection, remediation and restoration applications, where high relative humidity has to be checked closely to prevent mold growth.

Recommended and comfortable live-in conditions are about 70°F (20°C) and 35-50% relative humidity. If those conditions are maintained, wood will stabilize at 6-8% moisture.
