Measurement conditions
HM1500LF is specified for accurate measurements within 10 to
95% RH.
Excursion out of this range (<10% or >95% RH, including
condensation) does not affect the reliability of HM1500LF
characteristics.
Dedicated HM15XX products are available for extreme RH
conditions (as HM1520 for low dewpoints). Consult MEAS-
FRANCE for further information.
