PM880 AC

Panametrics portablehygrometer
The PM880 AC hygrometer is a complete portable systemwith options and accessories to meet all industrial moisturemeasurement needs.
This hygrometer is small, lightweight, and easy-to-use. Thelarge LCD displays moisture readings in dew point (°C or °F),ppmv, ppmw, lb/MMSCF (natural gas) and a variety of otherunit options. Data can be viewed in alphanumeric or graphic
formats. A 120 or 230 VAC power supply allows for continuous
operation of the analyzer.

Application
This rugged portable hygrometer measures moisture ingases and non-aqueous liquids. It is used in conjunction
with Moisture Image® Series (MIS), TF and M Series moistureprobes for applications including:• Natural gas• Chemical and petrochemical gases• Non-aqueous liquid applications• Air separation plants• Tanker preparation and fi lling• Industrial gases• Gas cylinder preparation and fi lling• Shipboard applications• SF6 circuit breakers• Furnace gases/heat treating• General plant/facility maintenanceFeatures
