Handheld Relative Humidity Meters
RH/Temperature Models Available
The RH-20 is a rugged handheld
digital meter which economically and
easily measures relative humidity and
temperature with an LCD readout. A
single probe containing both humidity
and temperature sensors attaches to
the meter with a 4.5' cable. Very
compact and portable, the RH20 is
ideal for checking RH in plant
maintenance, heating and
environmental industry and the high
technology computer industry.
