Standard pressure gauge Ø 160 mm, G 1/2 radial bottom, -1 to 0 bar, sheet steel case, type 8301 - Riegler 101982

This standard gauge displays vacuum from -1 to 0 bar purely mechanically via a bourdon tube, so it stays readable without power. Nominal size Ø 160 mm, G 1/2 connection radial bottom.

Key benefits

• Scale graduation 0.02 bar for accurate reading across -1 to 0 bar
• Accuracy class 1.6, equal to a permissible error of ±16 mbar over the span
• Ø 160 mm with bottom radial connection, G 1/2 male thread
• Sheet steel case, instrument glass window
• Medium and ambient temperature -20 to 60 °C

Typical use

Typical locations are vacuum systems, suction lines and vacuum generators. Permitted media are gases and liquids without high viscosity or tendency to crystallise that do not attack copper alloy.
