PM880 AC Accessories
1 Portable, infrared thermal printer and battery charger
This hygrometer is small, lightweight, and easy to use.
The large LCD displays moisture readings in dew point
(°C or °F), ppmv, ppmw, lb/MMSCF (natural gas), and a
variety of other unit options. Data can be viewed in
alphanumeric or graphic formats. A 120 or 230 VAC
power supply allows for continuous operation of the
analyzer.
The PM880 AC comes in a soft carrying case with
zippered compartments, a handle, and a shoulder strap.
The case accommodates the PM880 AC, a sample
system, fl exible hosing, probes with protective covers,
a Moisture Image Series probe electronics module, an
operating manual, power supply, and probe cables. The
carrying bag is safe for transporting the PM880 AC and
accessories around a site.
