RS PRO 50 mm G 1/8 G (BSPP) Plastic Case Analog Pressure Gauge, 4 bar, ±2.5% Accuracy 777-081

RS PRO 777-081 is a 50 mm dial analog pressure gauge featuring a plastic case and copper alloy pressure connection designed for precise measurement of pressures up to 4 bar. It operates on the reliable Bourdon tube mechanical principle, eliminating the need for electrical power or batteries. The dual scale display shows readings in bar and psi, making it versatile for various pressure measurement needs.

The gauge has a back entry connection location with a G 1/8 BSPP threaded connection, compatible with many industrial and commercial installations. It meets EN 837-1 standards with an accuracy rating of ±2.5% full scale deflection, ensuring dependable readings for critical applications.

Designed to handle ambient temperatures from -40°C to +60°C, it is suitable for use in pneumatic systems, heating and air conditioning technology, medical engineering, small capacity compressors, and hydraulic presses. Its plastic case provides robustness and resistance to environmental conditions, while copper alloy components ensure durability against corrosion.

The mechanical analog design supports one-way data interpretation without any need for an external power source, improving safety and reliability. Installation is straightforward, and the back entry design helps simplify mounting in confined spaces.

RS PRO's commitment to quality means each gauge undergoes stringent testing to deliver consistency and reliability under demanding conditions. This pressure gauge is an ideal solution for measuring gaseous and liquid media pressures, excluding highly viscous substances.

The gauge features a 50 mm dial with white colour and dual bar and psi scales for easy pressure reading. It operates on the Bourdon tube principle without requiring any power source, ensuring mechanical reliability. Accuracy is rated at ±2.5% full scale deflection according to EN 837-1 standards.

Constructed with a plastic case and copper alloy pressure connection for durability and corrosion resistance. Suitable for back entry installation with a BSP tapered thread connection size G 1/8.
