Ametek 303B Moisture Analyzer

The 303B offers a simple solution to the problem of measuring the moisture content of gas streams. The portable Moisture Monitor, built for NEC Division 2 areas, is designed to measure moisture content in gases such as air, nitrogen, argon, natural gas, and others with comparable characteristics. Based on Faraday’s Laws of Electrolysis, the 303B absorbs and electrolyzes moisture down to fractional parts-per-million and is linear to its 2000 parts-per-million-by-volume maximum reading. An electrolytic cell does not require calibration and is virtually specific to water so it can be used to monitor nearly all gases.

Applications

  • Monitoring natural gas pipelines and gas treatment processes
  • Monitoring air humidity in dry boxes
  • Continuous monitoring of atmospheres in simulated space chambers
  • Sensing elements in humidity control systems
  • Monitoring inert protective atmospheres in brazing or sintering furnaces
  • Monitoring moisture in many fluorocarbon gases
  • Constant measurement of batch and continuous driers to assure quality control without the expense of overdrying
  • Monitoring anhydrous batch chemical processes at startup
  • Quality control of transistor and diode backfill gas
  • Instrument air systems
  • Cryogenic processes
  • Radar waveguides
