303B Moisture Analyzer

Features

The 303B offers highly accurate portable measurement of trace moisture in gas streams for division 2 areas. Using an electrolytic (P2O5) sensor, the 303B can be used to monitor nearly all gases. It is compact, lightweight, and suitable for both portable use and permanent installation in Class I Div. 2 areas. With the optional carrying bag and lightweight design, the 303B is truly portable.

APPLICATIONS : The 303B is designed to measure moisture content in gases such as air, nitrogen, argon, natural gas, and others with comparable characteristics. Typical applications are:

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
