1. APPLICATION
Thermo-Hygrometer PCE-WM 1 is an electronic microprocessor based device for
measuring relative air humidity (%RH), temperature (°C), absolute humidity (g/m3) and dew
point temperature (°C). It is equipped with TP-1 Electrode which enables the user to obtain
temperature readings for various surfaces (e.g. steel constructions). Absolute humidity and
dew point temperature are calculated by the microprocessor, which performs linearization
and mathematical computations.
The device is widely used in industry and laboratories, it is extremely user friendly. It is
supplied together with other standard equipment in a shock proof case.

Absolute humidity is calculated by the microprocessor using formulas commonly known in
thermodynamics.
DEW POINT TEMPERATURE (°C)
Dew point temperature is determined by the microprocessor using a two dimensional
(humidity and temperature) table.

3. PREPARING THE INSTRUMENT FOR MEASUREMENTS
Before starting the measurement connect the probe to the instrument.
4. MEASUREMENTS
The instrument is turned on by pressing the ON/OFF button once. The results of
measurements of air temperature, relative humidity, dew point temperature and absolute
humidity are instantaneous after switching the knob to (respectively): TEMP.[°C], RH [%],
DEW POINT [°C], HUMIDITY [g/m
3
].
Surface temperature measurement should be conducted with the TP-1 electrode
connected to the mini-jack socket located in the lower part of the probe. Set the knob to
TEMP. [°C].
5. OUT OF RANGE INDICATION
The instrument indicates the results that are out of range in the following way:
1_ _.1 - upper temp. range exceeded (t>79.5°C),
-1_ _.1 - lower temp. range exceeded (t<-19.5°C),
1_ _.2 - upper RH range exceeded (RH%>99.9%),
-1_ _.2 - lower RH range exceeded (RH%<10%),
1_ _.3 - upper dew point temp. range exceeded
(t
dp
>79.5°C),
-1_ _.3 - lower dew point temp. range exceeded
(t
dp
<-19.5°C).
6. REPLACING THE BATTERY
The instrument is powered by one 9V battery type 6F22. The battery should be replaced
when the “LO BAT” sign is displayed on the LCD. To replace the battery remove the cap,
unscrew the screw holding the two halves of the case together and carefully separate them.
7. EXPLOITATION REMARKS
7.1 Do not allow the cold humidity sensor to come in contact with warm and humid air. This
causes condensation and totally falsifies the results. Condensation does not damage the
sensors nor does it change its characteristic.
7.2 Humidity sensor is not resistant to acetone or other chemical solvents.
7.3 If the sensors become dusted wash it gently with alcohol and let to dry. Mechanical
cleaning is not allowed as it may case scratches.
8. HUMIDITY STANDARDS
Periodical verification of the Thermo-Hygrometer PCE-WM 1 operation can be done with
appropriate saturated salts solutions or humidity generators. Checking can be done by the
manufacturer or other specialized company. It is recommended to calibrate the instrument
every 12 months.
9. GUARANTEE AND SERVICE
PCE.Group warrants the Thermo-Hygrometer PCE-WM 1 to be free from malfunction and
defects in both materials and workmanship for one year (12 months) from the date of
purchase.
