HTG3500 series modules are specified for maximum accuracy measurements within 10 to 95 %RH.
Excursion out of this range (< 10% or > 95% RH, including condensation) does not affect the reliability of
HTG3500 series characteristics.

Typical temperature output
Depending on the needed temperature measurement range and associated accuracy, we suggest two methods

The exponential relation only roughly describes the actual characteristic of an NTC thermistor can, however,
as the material parameter β in reality also depend on temperature. So this approach is suitable for describing a
restricted range around the rated temperature or resistance with sufficient accuracy.
For practical applications, a more precise description of the real R/T curve may be required. Either more
complicated approaches (e.g. the Steinhart-Hart equation) are used or the resistance/temperature relation as
given in tabulation form. The below table has been experimentally determined with utmost accuracy for
temperature increments of 1 degree.
Actual values may also be influenced by inherent self-heating properties of NTCs. Please refer to MEAS-France
