Small measuring ranges and fast measurements are characteristic of the Caldos27 thanks to its silicon sensor.  The smallest volumes and the direct coupling to the gas feed path result in extremely short T₉₀ times.  The measuring ranges can be freely selected.  The extremely high long-time stability of the sensor largely enables single-point calibration with only one gas.

Typical Applications

- Hydrogen purity measurement
- Turbo generator monitoring
- Inert gas monitoring
- Monitoring of explosive limits

Sample Components

More than 30 binary gas mixtures are configurable.  The active measuring component can be selected out of four (4) gas mixtures.

Calibration

- Zero-point calibration with sample component-free process gas or substitute gas
- End-point calibrations with a known process gas concentration or with a         
  substitute gas
- Simplified calibration with a standard gas avoids the need for separate zero and
  end-point calibrations
- Automatic calibrations

Dynamic Response

- T₉₀ time < 2 s
