Span Pac™ Series I Industrial Gas Standards Generators are used in industrial, process and/or hazardous environments. These instruments use Trace Source™ permeation tubes to deliver calibration standards directly to your FTIR, GC, GC-MS, Ion Mobility Spectrometer or any type of gas analyzer or environmental chamber.

The Span Pac™ Series I Gas Standards Generator provides the temperature controlled environment and carrier gas control for Trace Source™ Disposable Permeation Tubes. These generators can also provide the refilling mechanism for gas filled Trace Source™ Refillable Permeation Tubes.

The Span Pac™ I is specifically designed for field mounting and can be operated from a remote station. Multiple permeation tube ovens can be housed in a single NEMA 4 cabinet. The instrument is also available with Z purge.

Benefits include:

• Economical - replaces expensive, unreliable gas cylinder mixtures
• Safe - limits possibility of exposure to hazardous materials
• Reliable - continuous service; accuracy can be verified by user
• Automated - can be operated by the analyzer or computerized process control system
• Traceable accuracy - permeation tube output measured by weight loss
• Rugged construction - NEMA 4 housing withstands industrial environment
