Every 303B is equipped with the following:
- digital display
- rugged moisture cell
- bypass flowmeter
- 4 to 20 mA output
- internal battery and recharging system
- AC and 12VDC power inputs
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
