The Model 510 P2O5 Trace Moisture Analyzer by Illinois Instruments uses a phosphorus pentoxide (P2O5) sensor to accurately measure moisture from 0-1000 parts-per-million (ppm) in inert gas streams.  The P2O5 sensor technology is preferred for its accuracy at low levels.  The P2O5 sensor also does not require any calibration.

The P2O5 sensor is an electrolytic sensor.  P2O5 coats a dual platinum winding in which a known current passes through.  Water molecules are absorbed into the P2O5 and hit the electric current.  The water molecules break apart into oxygen and hydrogen.  The breaking apart of the molecules consumes some amount of the electric current that can be measured by the resistance across the platinum windings.  The P2O5 sensor theory follows Faraday’s Law which basically states that it takes a known amount of energy to break a given molecular bond.

The Series 500 P2O5 Trace Moisture Analyzer can be configured in a variety of ways to suit your specific application.  It is available as a benchtop/panel mountable cabinet, a NEMA 4X wall mount cabinet, or in a 19 inch rack mountable cabinet.  In addition, the P2O5 trace moisture analyzer can have a remote mounted sensor for general purpose areas.

Illinois Instruments' Series 500 Moisture Analyzers represent our latest advancement in moisture analysis. This series was designed to be customized to your application while providing a simple, yet affordable analyzer.  The Series 500 Moisture Analyzers incorporates microprocessor control with our high quality electrolytic moisture sensor to bring flexibility to your process environment. These analyzers provide accurate depend-able results over a wide range from 0.1 ppm to 1000 ppm.

All models feature microprocessor control for stable and repeatable operation. A bright, autoranging LED display provides direct measurement output. User-adjustable alarms, scaleable analog output signals, RS232 interfacing, and process sample bypass flow systems are all optionally available.

Three different configurations add to the base Model 510 (shown at right) to offer the choices needed to satisfy virtually all industrial environment and operational constraints.
