The Regi REGIU33 Premier ‘30 gauge (reduced scale 30 mbar) is a professional-grade pressure gauge designed for accurate low-pressure measurement in combustion, boiler and HVAC systems. Calibrated specifically on a reduced 30 mbar scale, it allows engineers and service technicians to read small pressure variations with improved resolution and clarity—ideal for tasks such as boiler gas pressure checks, flue draught measurements, burner tuning, and draft monitoring. Built for everyday trade use, this gauge combines robust construction with a clear, easy-to-interpret dial to help ensure reliable on-site diagnostics.

This 30 mbar reduced-scale gauge is compatible with standard manometer and pressure tap connections used in gas, boiler and HVAC applications where low-pressure measurement is required. Because fitting requirements can vary by system and inlet size, it’s recommended to verify that the gauge matches the pressure range and port specification of your measurement setup before use.

Key features of the Regi REGIU33 Premier ‘30 gauge include its precise reduced 30 mbar scale for enhanced resolution of low pressures, durable construction for dependable field performance, clear and well-marked dial for quick interpretation of readings, straightforward installation into compatible test points or manifolds, and practical utility when used by qualified engineers and technicians during measurement, commissioning and servicing tasks.
