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.
