HK Instruments MM Series Installation Instructions

INTRODUCTION
Thank you for choosing an HK Instruments MM Series liquid col-
umn manometer. The MM Series is intended for use in commercial
environments for air and non-corrosive gases. The MM Series is
designed with overpressure reservoir to protect the manometer
liquid from leaking into the duct during over pressure.
The MM Series includes a field adjustable zero point calibration
and pressure limit stickers. The MM Series is available with op-
tional level bubble and NIST standard calibration certificates.
APPLICATIONS
MM series devices are commonly used in HVAC/R systems for:
• fan, blower and filter monitoring
• pressure and flow monitoring
• pressure monitoring in cleanrooms
