Liquid column manometers

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 an overpressure situation.


MM series device features include:
• field adjustable zero point calibration
• pressure limit stickers


The MM series device options offer:
• level bubble
