MM Inclined 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
