Self-cleaning dew point monitor
The Dew Stat MA-99 Dew Point Monitor from General Eastern Instruments has a self-cleaning feature to help accurately measure dew point temperature of compressed air in hospital breathing air systems.
The MA-99 meets the NFPA-99 requirement for dew point measurement to ensure that the dew point in compressed air breathing systems shall not exceed 39°F. The monitor integrates a chilled mirror dew point sensor, all associated electronics, and a flow control system with visual verification or proper flow.
A bright LED display gives continuous dew point temperature readings. The system automatically cleans the mirror with a blast of compressed air at regular intervals. An on-board microprocessor monitors all critical functions and lights a front panel indicator during an autoclean cycle.
If the dew point exceeds the factory pre-set (but user changeable) temperature of 39°F, an alarm sounds. The alarm consists of a relay output, a visual indicator on the front panel, and a loud audible signal.
