REFCO Oil Filled Compound & Pressure Gauge – MR Series
Professional REFCO analog refrigeration gauges for pressure monitoring, system servicing and HVAC/R applications, available with multiple refrigerant scales, connection arrangements and gauge sizes.
Oil Filled Class 1.6 bar / psi Bottom Connection Back Connection HVAC/R📊 REFCO MR Series Refrigeration Gauge
The REFCO MR Series Oil Filled Compound & Pressure Gauge is designed for professional refrigeration and air-conditioning pressure measurement.
Different versions are available for R22, R134a, R407C and R32, together with MULTI versions covering multiple refrigerant temperature scales.
The range includes standard bottom-connected gauges as well as front- and back-mounting configurations for different installation requirements.
The liquid filling helps dampen pointer movement caused by pressure pulsation and vibration, making the gauge easier to read during HVAC/R servicing while helping protect the internal measuring mechanism.
