Standard pressure gauge Ø 160 mm, G 1/2 radial bottom, -1200 to 0 mbar, sheet steel case, type 8300 - Riegler 101981

This standard gauge displays vacuum from -1200 to 0 mbar 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

• Accuracy class 1.6, equal to a permissible error of ±19.2 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
• Scale graduation 20 mbar for accurate reading across -1200 to 0 mbar

Typical use

Common measuring points: vacuum systems, suction lines and vacuum generators. The gauge handles gaseous and liquid media that are neither highly viscous nor crystallising and do not corrode copper alloy.
