Base configurations in the table below can be configured to meet user requirements for dilution gas and carrier gas flow capacities.
Automated Models | Manual Models |
- User sets either the flow rate or the concentration via touch screen
- Required temperature and concentration or flow rate or set and controlled automatically
- External gas source
|
- Concentrations are calculated manually
- Required temperatures and flow rates are set manually
- Internal pump or external gas source
|
Model 235 – Basic
- Provides continuous dilution
- Maintains a constant carrier flow through the permeation chamber
|
Model 230 – Basic
- Provides continuous dilution
- Maintains a constant carrier flow through the permeation chamber
|
Model 345 – Intermediate/extended concentration range
- In the zero mode, scrubbed dilution flow is delivered to the outlet, allowing the end user to establish zero before sampling
- Full range of mode capability
|
Model 340 – Intermediate
- Zero function as described at left
|
Model 450 – Extended concentration range
- Mode switch selects among standby (through), zero, span 1 (low concentration), and span 2 (high concentration) modes
|
Model 505 – Dual chamber
- Two separate permeation chambers with independent temperature control systems
- Chamber 1 and chamber 2 can run independently, or be used together to combine trace components
- Solenoid valves allow the carrier flows to be switched from the dilution stream to a vent port, allowing chamber 1, chamber 2, chamber 1 + chamber 2, or zero
|
Model 500 – Dual chamber
- Two separate permeation chambers with independent temperature control systems
- Chamber 1 and chamber 2 can run independently, or be used together to combine trace components
- Solenoid valves allow the carrier flows to be switched from the dilution stream to a vent port, allowing chamber 1, chamber 2, chamber 1 + chamber 2, or zero
