DeFelsko PosiTector DPM Dew Point Meter


The new ergonomic design of DeFelsko's PosiTector DPM DewPoint Meter brings greater versatility and convenience to all coatings inspection applications. Dew point measurement is an important and necessary aspect of preparation for coatings application, to ensure proper adhesion of coatings to surface. With PosiTector DewPoint Meter, measurement of relative humidity, surface temperature, air temperature, dew point temperature, and difference between surface and dewpoint temperatures, is performed simultaneously with a single gauge, with no need to consult complex tables or use a dewpoint calculator. Read all measurement parameters easily on the large LCD display, store measurements internally in the gauge, download readings to your computer, or upload to DeFelsko’s cloud-based application, PosiSoft.net. PosiTector DPM can be set up to AutoLog at user-selected intervals for continuous monitoring of all measurement values.



PosiTector Dew Point Meter now offers five probe styles which are fully compatible with both Standard and Advanced Gauge bodies:

PosiTector DPM - integral probe with built-in air temperature/rh/dewpoint sensor and integrated surface temperature probe

PosiTector DPMS - integral air tempreature/humidity/dewpoint sensor with cabled, K-type magnetic surface temperature probe

DPMA - new! - measure ambient temperature, relative humidity, dewpoint, surface temperature, with hot-wire anemometer to measure wind speed

DPMD - new! - measures dew point, relative humidity, and air temperature, with sintered aluminum housing and ½" NPT threads for insertion into tanks & pipes (max 200 psi / 1.3 MPa)

DPM-IR - new! - measures air temperature, relative humidity, dewpoint, and non-contact surface temperature with infrared surface sensor. Ideal for surface temperature measurement of hard-to-reach or moving parts. 4:1 distance-to-spot ratio is optimized for measuring large surfaces. DPM IR features both pre-programmed and user-adjustable emissivity options to allow accurate temperature measurements indoors or outside.

 

 

 

 

DPM and DPM-S also connect wirelessly to your mobile device using the PosiTector SmartLink . The DPM Integrated Probe has the RH and air temperature sensor with a built-in surface temperature probe.

 

 

 

The DPMS Separate Probe is equipped with integrated RH and air temperature sensor, a magnetic surface temperature sensor on a K-type thermocouple with armoured cable, and a magnetic mount in the supplied rubber holster to mount the gauge on steel structures for continuous monitoring of climatic conditions. The separate DPM probe attachment accepts other optional K-type sensors, including DeFelsko's liquid temperature and self-adhering probes.
