The Span Pac™ H₂O Generator is specifically designed to calibrate sensitive moisture analyzers. It uses a Trace Source™ Permeation Tube to generate low concentration (10 ppm to 100 ppb) moisture standards.

The Span Pac™ H₂O Generator holds the Trace Source™ Permeation Tube at a constant temperature and introduces a controlled flow of dilution gas over the tube. A small, accurate, constant flow of H₂O vapour permeates from the tube and mixes with the dry dilution gas to form the ppm or ppb moisture standard. The moisture standard then flows through the generator output to a monitor or probe.

The Span Pac™ H₂O Trace Moisture Gas Standard Generator provides:

· H₂O concentrations adjustable over 20:1 range with single oven; 400:1 with dual oven system; 10,000:1 with secondary dilution mass flow.

· Concentrations within 0.01 to 10,000 ppm H₂O range depending on model selection.

· H₂O concentrations below 100 ppb with welded model.

· Industrial models have NEMA 4 cabinets and optional Z or X purge capability.

· Uses KIN-TEK Trace Source™ disposable and user-refillable water permeation tubes.
