Compact and Accurate: 150mbar High Specific Gravity Fluid Gauge (J Gauge) The 150mbar High Specific Gravity Fluid Gauge, also known as the J Gauge, is designed to provide precise pressure measurements with reduced height requirements. Utilising high specific gravity fluid, this U gauge effectively minimizes the normal 60 height to just 38, while still maintaining a measurement range of 60 (150 mbar). Wide Measurement Range: Measures 0-150 mbar or 0-60 w.g., suitable for a variety of applications. Compact Design: With a length of only 96cm (29) and weight of 1kg (2.2lbs), it's easy to handle and transport. Clear and Precise Readings: Provides accurate readings down to 0.5 mbar (1/10 w.g.). Ready to Use: No need
