HK Instruments DPG Series Manual

INTRODUCTION
Thank you for choosing an HK Instruments DPG/PS series filter
alert. In many situations filter monitoring requires an alarm signal
and a local display. Our filter alerts are the right solution for these
situations. The DPG/PS filter alerts combine differential pressure
switches with gauges into one practical product offering.
APPLICATIONS
The filter alerts are a solution for systems requiring visual indication of
pressure on site and a switching point signal. The filter alerts are ideal
for general-purpose work in air-conditioning and ventilation, especially
SPECIFICATIONS
in monitoring of air filters for contamination.
