7.9  Some Basics of Precision Temperature Measuring 

Probe Precision/Device Precision  

The device is very precise (please refer to technical data). To be able to use this 
high precision, the connected temperature probe has to be as precise as 
possible, too. The following precision classes are available as a standard at 
reasonable prices (Platinum resistor thermometers according to EN60751):  

 

     Class 

 

 

 

Error ranges 

  B 

 

 

 

 

  ± (0,3 + 0,005 • |temperature|) 

  1/3 B  (=1/3 DIN)    

 

  ± (0,1 + 0,0017 |temperature|) 

  1/10 B  (=1/10 DIN)   

  ± (0,03 + 0,0005 • |temperature|) 

  A 

 

 

 

 

  ± (0,15 + 0,002 • |temperature|) 

 

 

 

Error over measuring range 

 

Error over range -50...150 °C 

 
For applications demanding higher precision than given by these classes we 
suggest to adjust the device to the used probe or to get a calibration certificate for 
the device combined with the probe.  
 

Attention:  if  an  adjusted  or  calibrated  probe  is  replaced,  also  the 

adjustment  or  calibration  certificate  has  to  be  renewed  to  maintain  the 
referring overall precision! Be careful when buying third party temperature 
probes:  Besides  the  standard  EN60751  there  are  some  other  obsolete  or 
unusual standards on the market. If such a probe has to be connected, the 

user  sensor  curve  (have  a  look  to  the  referring  chapter)  can  be  used  to 
adjust the instrument!
