PM880

Panametrics portablehygrometer
The PM880 hygrometer is a complete, intrinsically safe, portablesystem with options and accessories to meet all industrial
moisture measurement needs.
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 otherunit options. Data can be viewed in alphanumeric or graphic
formats. A rechargeable battery pack and battery charger
make this the ideal go-anywhere moisture analyzer.

ApplicationThis rugged, intrinsically safe, portable hygrometer measuresmoisture in gases and non-aqueous liquids. It is used inconjunction with Moisture Image® Series (MIS), TF and M
Series moisture probes 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
