HK Instruments DPG Series Installation Instructions

INTRODUCTION

Thank you for choosing an HK Instruments DPG Series differential
pressure gauge. The DPG Series is intended for use in commercial
environments in HVAC/R applications. It is designed to detect air
and non-corrosive gas pressures (differential and positive) and to
provide a clear analog display of the measured values.
The DPG Series includes field adjustable zero point calibration and
overpressure protection. The DPG Series is available with NIST
standard calibration certificates.

APPLICATIONS

DPG series devices are commonly used in HVAC/R systems for:
• fan, blower and filter monitoring
• pressure and flow monitoring
• monitoring static pressure
