Model DSP-Rm is a fully self-contained portable
hygrometer from Alpha Moisture Systems which will
deliver the most dependable moisture measurement in
industrial and laboratory applications. Designed with the
operator in mind, Model DSP-Rm is extremely easy to use
and the digital dewSMART™ technology ensures accurate
and reliable readings over long periods with little or no
maintenance. The incorporation of stainless steel quick
connect fittings, together with the Desiccant Dry-down
Chamber, allows rapid measurements which saves both
time and cost.
Model DSP-Rm can operate form a mains power supply
or standard rechargeable batteries. Designed to operate at
atmospheric pressure, Model DSP-Rm is available in a
total of six different ranges, encompassing an overall range
from -110°C to +20°C dewpoint, with the display selectable
in various engineering units:- °C, °F, ppm(v), ppb(v),
ppm(w), g/m³ & lb/MMSCF. Parts per million (weight) can
be programmed for gases other than those preprogrammed (Air, Ar, H2, SF6, CO2 & N2) by simply
inputting the molecular weight of the gas under test.
Full interchangeability of the dewSMART™ Sensor
ensures guaranteed accuracy and reliability without the
need to return the whole unit back to base for calibration
and setup.

To allow rapid spot checks it is essential that the measuring sensor is
kept drier than the sample to be measured. The desiccant dry-down
chamber is designed to do just this by keeping the sensor surrounded by
desiccant when the instrument is not in use, only exposing it to the
sample gas when taking measurements. At no stage is the sensor
allowed to come into contact with ambient air.
