Introduction Introduction
The
PosiTector DPM L Dew Point Meter Logger
(DPM L) is a
compact wireless probe that measures, calculates, and records
climatic conditions quickly and accurately. It consists of an IP65
rated water/weather resistant housing with air temperature,
humidity and magnetic surface temperature sensors. The
PosiTector DPM L
communicates with the
PosiTector App
or
PosiTector Advanced
instruments (serial number 784000 and
greater) using Bluetooth wireless technology.
The
PosiTector DPM L
measures and records the following
parameters (dataset):
RH
Relative Humidity (measured)
Ta
Air Temperature (measured)
Ts
Surface Temperature (measured)
Td
Dew Point Temperature (calculated)
Ts-Td
Surface
minus
Dew Point Temperature (calculated)
Tw
Wet Bulb Temperature (calculated)
To ensure optimal performance of the
PosiTector
DPM L
probe, do not obstruct the airflow near the air temperature
and humidity sensors. Keep fingers away from the sensor, as body
heat can influence readings. Allow time for the probe to acclimate
and for the readings to stabilize when moving the probe between
different environments. When attaching a probe to the surface, do
not use excessive downward force, and do not drag it sideways.
When not in use, place the probe into the protective plastic case to
prevent damage.
