USER-FRIENDLY MEASURING DEVICES differential pressure gauges and manometers mm series Liquid column manometer for HVAC applications The MM series liquid column manometers are engineered for HVAC/R applications. The MM series devices detect air and non-corrosive gas pressures (differential, vacuum and positive) and provide a clear analog display of the measured values. The MM series is designed with a reservoir to protect the manometer liquid from leaking into the duct during overpressure situation. MM series device features include: • field adjustable zero point calibration • pressure limit stickers The MM series device options offer: • level bubble similar products applications • DPG series differential pressure gauges MM series devices are commonly used in HVAC/R systems for: • MMU series U-tube manometers • fan, blower and filter monitoring • pressure and flow monitoring • pressure monitoring in cleanrooms Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 4.0 2017
