Sample Dryers
Features:
- Highly efficient permeable-membrane dryer
- Dries to -10C dewpoint with saturated input
- Does not interact with other sample gases
- Sample flow rate variable from 25-200 ml/minute
- Negligible internal volume
- Rugged, light, low power consumption
The ND-2 gas sample dryer dries saturated air at 25oC to a dewpoint of -10oC, corresponding to a water vapor pressure of 0.26 kPa. The ND-2 is ideal for subsampling and drying gases prior to analysis. The ND-2 is also available without a pump (model ND-2V) for use with an existing pump or vacuum source.Features:
- Dry air to 1 degree C dewpoint (settable at 1-5C)
- Robust, quiet Peltier effect technology
- Reduces or eliminates chemical desiccators
- Analog plus serial outputs for data-logging
- Automatic intermittent condensate drain
- Rugged, light, low power consumption
The PC-4 sample dryer condenses water vapor from an airstream, drying the airstream to a dewpoint of 1 degree C (user-settable between 1 and 5 C). This reduces the water vapor pressure in the airstream to no more than 0.66 kPa (at 1 C), at which point the dilution effect of water vapor in the air sample is negligible in many applications.
