The glycerin filling dampens vibrations and pulsations, protecting the internal components and providing stable readings, even in fluctuating pressure environments. It also lubricates the movement, extending the gauge's lifespan.Maximum Medium Temperature: 140 °F/60 °C. Ambient Temperature : -4 to 140 °F/-20 to 60 °C . IP67 meaning it is dustproof and waterproof.
The gauge has a diameter of 2 inches, making it easy to read and install in various settings. This size is standard for many pressure gauge applications, offering a clear view of the pressure readings.
