User-friendly operation, reliability, and accuracy, has made this miniature thermohygrometer popular with museums the world over.

Our calibrated Arten Meter is ideal for use in exhibit cases and microclimate boxes where a low profile is desirable. The humidity indicator strip on the lower portion of the meter reads from 15% to 75% relative humidity (RH) and provides an independent reading to verify that the meter is properly calibrated. The meter is very easy to re-calibrate and is available with temperature measurement in either Fahrenheit or Centigrade. So long as no mechanical damage has occurred, this tiny meter will last an indefinite amount of time.

Calibration Kit order ]
This kit is used to re-calibrate our Arten Mechanical Themrohygrometer. Over a period of a few months, the Arten Meter may lose accuracy and will need to undergo calibration.

The Arten Thermohygrometer humidity calibration kit consists of five sealed moisture barrier envelopes, each containing one Ziploc polyethylene bag and a packet of silica gel conditioned to 50% (+2%) relative humidity. One kit is good for five calibrations.
