Technical content

The PM880 hygrometer is a complete, intrinsically safe, portable system 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 other unit 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. Application This rugged, intrinsically safe, portable hygrometer measures moisture in gases and non-aqueous liquids. It is used in conjunction 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

• Hand-held portable design
• Intrinsically safe
• IP67 rated
• Large graphic display
• Internal data logger
• IrDA® communication with PC
• Stores up to 60 log/site files
• Simple programming via graphic user interface
• Compatible with all Panametrics moisture probes
• Lightweight hand-held sample system
• Convenient carrying bag to store hygrometer and all accessories The PM880 comes in a soft carrying case with zippered compartments, a handle and a shoulder strap. The case accommodates the PM880, a sample system, flexible hosing, probes with protective covers, a Moisture Image Series probe electronics module, an operating manual, a battery pack, a battery charger and probe cables. Training for the PM880 is available on-site, in the factory or online. Panametrics offers extended warranties and service agreements for the PM880 as well as a range of services including NIST-traceable calibration, field calibration, rentals and moisture surveys.
