HTM1505 is specified for accurate mea-
surements within 10 to 95% RH.
Excursion out of this range (< 10%
or > 95% RH, including condensation)
does not affect the reliability
of HTM1505 characteristics.
Dedicated HTM15XX Product are avail-
able for extreme RH conditions (as
HTM1525 for low dewpoints) - Consult
HUMIREL for further information.
