Veronics Instruments Inc. represents the Panametrics line of reliable Hygrometers and Moisture Meters with a combination of features to meet your needs and budget. Learn more about the following products:

moisture.IQ

Part of the IQ Series of moisture and oxygen analyzers from Panametrics, the moisture.IQ is a multichannel, multifunction analyzer used wherever moisture impacts the quality, efficiency, or performance of a product or process. The new touchscreen display and graphics-based interface allow for easy at-a-glance viewing. The built-in auxiliary inputs allow you to add two additional transmitters and an oxygen measurement to each available channel-making it the most versatile moisture analyzer on the market.


  • Multichannel transmitter all in one box
  • Combines the technology of the MIS-1 and the MMS-3 into one core product
  • Real-time clock and data logging for enhanced monitoring and troubleshooting
  • Easily upgrade your current Panametrics hygrometer
  • The global reach and local support of GE

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
  • Air dryer
  • Pharmaceutical
  • Aerospace

Aurora TDLAS Hygrometer

Panametrics Aurora analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to measure moisture in natural gas rapidly and accurately. The analyzer is suitable for installation in hazardous areas and operates over a wide range of environmental conditions. Aurora’s fast response quickly alerts and documents when moisture concentrations are out of compliance. Once process upsets are corrected and the gas dries out, the fast response enables natural gas to be cleared for entry into the “energy grid.”

Panametrics experience in moisture measurement includes aluminum oxide, polymer capacitance and chilled mirror sensors. Panametrics heritage also includes the development of the first injection diode laser in 1962 by Dr. Robert Hall in Schenectady, NY. The compact and inexpensive diode laser made it possible for compact discs, laser printers and fiber optic telecommunications. The new Aurora TDLAS hygrometer enables natural gas processing and transportation facilities to monitor moisture content in real time with high precision and reliability.
