-1..0 Bar (-15..0 psi) Pressure Gauge Rear Plastic/Brass 40 mm Class 2.5

The pressure gauge MW-1040PH-18 is designed for vacuum applications and measures pressures within the range of -1 to 0 bar (-15..0 psi). The gauge has two measurement scales in bar (black) with scale division of 0.05 and in psi (red). The measurement accuracy class is 2.5 (± 2.5 % maximum deviation). The gauge body is made of plastic, the connection and indicator are made of brass. Please make sure that your medium is compatible with brass. The connection point for this manometer is located rear the gauge. As a rule of thumb, please select a pressure gauge that has a rating scale of at least 25% higher than the maximum operating pressure.

This pressure gauge is suitable for: gaseous and liquid media that are not highly viscous or crystallising and will not attack copper alloy parts, pneumatics, heating and air-conditioning technology.

Pros and cons:

• The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges
• Reliable and cost-effective
• Design per EN 837-1
• Two measurement scales, bar and psi
• Suitable for vacuum applications

MW Series

The MW Series pressure gauges are available with a vertical or horizontal type connection. The pressure element is a bourdon tube. The gauge diameter is 40, 50 or 63 mm, the accuracy class 1.6 for steel housing and 2.5 for plastic housing. The measurement range for the gauges of this series is from -1 to 400 bar. Scale division ranges from 0.02 to 50 bar. The gauges are made of plastic or steel, the window material is made of polycarbonat, the connection has a thread size of G 1/8 inch or G 1/4 inch and is made of brass. Make sure that your medium is compatible with brass. The gauges can operate at temperature -20°C to + 60°C.

A calibration certificate is not available.
