The alarm function fitted to most of our instruments provides a red warning light on the front of the instrument and access to a single pole change over relay which may be used to control external equipment.
In some cases an audible alarm is required and Model SAA has been designed for use where no other alarm unit is available.
110 or 230V a.c. power is needed for the Model SAA and it may be located close to the Dewpoint Analyser, or in any other convenient position. When energised it emits a pulsed tone of 73dbA at 3 metres. A red warning lamp on the front of the unit will silence the output when pressed, but the warning lamp remains on until the alarm condition ends. The unit resets itself automatically. Rated IP65 for outdoor use.
