The Panametrics PM880AC hygrometer is a rugged, line-powered, portable hygrometer that measures moisture in gases and non-aqueous liquids. The PM880AC available with a number of options and accessories to meet all industrial moisture measurement needs. The PM880AC is non-intrinsically safe. For applications requiring an intrinsically safe unit, please consider the Panametrics PM880 Hygrometer

The PM880AC is small, lightweight, and easy to use. Utilizing the proven aluminum oxide moisture sensor, the unit can express the absolute humidity of gases and liquids in dew point temperature, parts per million by volume (PPMv), parts per million by weight (PPMw), pounds per million standard cubic feet in natural gas, relative humidity, and other measurement units. Results are displayed on a 240 x 200 pixel, graphic backlit LCD display. A 25-key keypad with a rubberized, tactile membrane makes navigation simple. Data can be viewed in alphanumeric or graphic formats. The PM880AC comes with full data logging capabilities and a built-in infrared port to send data to a PC for detailed analysis and reporting. A 120 or 230 VAC power supply allows for continuous operation of the analyzer.

The PM880AC is compatible with Panametrics' Moisture Image Series (MIS), TF and M Series moisture probes. A probe and sample cell are required and can be purchase as accessories or as a complete system. The unit ships complete with a protective boot, soft carrying case, and 10' cable.

Applications for the Panametrics PM880AC:

  • Chemical and petrochemical gases
  • Non-aqueous liquid applications
  • Air separation plants
  • Tanker preparation and filling
  • Industrial gases
  • Gas cylinder preparation and filling
  • Shipboard applications
  • SF6 circuit breakers
  • Furnace gases/heat treating
  • General plant/facility maintenance
