Portable dew point indicator TRB100A

The TRB100A is a robust mobile instrument for measuring the pressure dew point in
compressed air and nitrogen. The measuring air flow can be controlled to quickly flush the measuring chamber if
required. The large LED display. The integrated 4-20 mA output lets you connect data loggers or other long-term
recording devices.
