U3631M, U3631G 

Compact thermometer - 
hygrometer with optional external 
temperature probe

 

 

This  model  is  designed  to  measure  temperature, 

relative humidity and dew-point temperature by internal 
sensor,  moreover  one  additional  external  temperature 
probe  Pt1000/E  can  be  connected.  Internal  sensors 
are located  under  the  grid  on  the  front  of  the  device. 

The device 

also 

measures 

the 

temperature 

from an external  probe  and  the  difference  between 
this temperature 

and the dew 

point 

temperature. 

If the surface  temperature  of  the  material  is  measured 
by an external probe, the risk of condensation of water 
vapor on the surface to be measured can be determined 
immediately.

 The device alone is suitable for measuring 

in places where there is no rapid change in temperature 
or  relative  humidity,  and  there  is  no  condensation 
of water vapours. If water vapour condensation occurs 
inside  the  datalogger,  then  the  resulting  water 
will remain  there  and  may  damage  its  electronics. 
The device  is  placed  directly  in  the  measured  area, 
while  the installation  needs  to  ensure  sufficient  level 
of mobile  signal  at  the  installation  location.  As  the 
internal  battery  creates  a  parasitic  heat  during  the 
charging  period,  the measurement  accuracy  may  be 
affected by up to 1 º C.

 

We  recommend  calibrating  the  relative  humidity 
and temperature  of  this  device  in  the  laboratory 
with a sufficient air flow (at least 1 m / s), the reading can 
be performed only after thorough settling, which can take 
up to 4 hours.

 

The  maximum  length  of  each  probe  lead  should  not 
exceed 15 m. It is recommended to use shielded cables. 
To maintain the IP rating, the unused probe connector 
should be provided with a supplied closing cap.
