DeFelsko PosiTector DPM L Dew Point Meter Logger
Description
![]()

The DeFelsko DPM L Dew Point Meter Logger monitors climatic conditions by attaching to steel structures with its magnetic probe. This probe measures and records relative humidity, air temperature, surface temperature, dew point temperature, wet bulb temperature, and the difference between surface and dew point temperatures. The Dew Point Meter Logger is equipped with precision sensors that provide fast, repeatable readings with a high level of accuracy. The PosiTector DPM L can record environmental parameters independently for up to 200 days and includes an alarm for when conditions exceed user-selected parameters. Every stored dataset is time stamped and can be downloaded using an Apple or Android smart device or an Advanced PosiTector gage body.
The Dew Point Meter Logger is designed with an environmentally sealed enclosure to be dust, shock, and weatherproof, meeting or exceeding IP65 standards. The probe also conforms to national and international standards, including ISO and ASTM. For anti-theft protection, a Kensington Security Slot is included, but the Kensington Lock must be purchased separately.
