“FS” (full scale) refers to the full dynamic range; “IV” refers to “initial value.”
* The best accuracy achievable when measuring relative humidity is strongly dependent upon the type of fluid or fluid
additive(s) involved. More precise information on this is available on request.
** The measurement accuracy of relative changes in viscosity and in dielectric constant vary according to the
application, the types of fluids involved, and the sensor’s own calibration. More detailed information on this is
available on request.
