Moisture Image Series 1 Analyzer

Moisture Analyzer

The Moisture Image Series 1 is the multichannel, multifunction top-of-the-line model in the GE moisture series analyzer family. The Moisture Image Series 1 measures moisture, pressure and temperature in non-aqueous liquids and gases. There is also an option for measuring oxygen concentration in gases. In addition, the auxiliary inputs can accept readings from any sensor with 0/4 to 20 mA or 0 to 4 V output, including a variety of GE process control instruments. This feature makes the Moisture Image Series 1 a true multifunction analyzer, providing cost savings through system integration.

 

For additional cost savings, the Moisture Image Series 1 is available with up to six channels to significantly reduce the cost-per-measurement point while providing a variety of configurations to meet the needs of specific applications.

 

This state-of-the-art instrument features simultaneous real-time display of six points of moisture, oxygen, temperature, pressure and other data from up to six channels on a large, backlit liquid crystal display (LCD). Menu-driven function keys provide easy access to data displayed in matrix and line-graph formats.

 

The Moisture Image Series 1 is complemented by the Moisture Image Series probe. It measures moisture, temperature and pressure, eliminating the need for additional external pressure transmitters and related power supplies. It is suitable for laboratory and industrial moisture measurement applications in gases and non-aqueous liquids over a wide range of process conditions. The Moisture Image Series 1 can also be used with any Panametrics moisture probe configuration. All moisture probe calibrations are NIST traceable.

Features

  • Optional pressure and temperature inputs used to calculate various parameters
  • Calibrations traceable to National Institute of Standards and Technology (NIST)
  • Rack, bench, panel, weatherproof (Type 4X) and explosion-proof (Type 7) configurations available
  • Computer-enhanced response software for abrupt dry-down applications
  • Real time matrix display of six parameters simultaneously
  • Measures other parameters via auxiliary inputs
  • Displays trace measurements in ppbv
  • Built-in data logging
  • PCMCIA card slot for additional memory and instrument program updates

Applications

This multichannel analyzer measures moisture in gases and non-aqueous liquids and oxygen (optional) in gases. Designed for permanent installations, it is used in conjunction with Moisture Image Series, TF and M Series moisture probes for industries including:

  • Petrochemical
  • Natural gas
  • Industrial gas
  • Semiconductor
  • Furnace gas/heat treating
  • Power generation
