Benefits of Glycerine filled pressure gauge

　　It stabilizes the needle. If there is no liquid-filled gauge, the pointer will bounce irregularly, making it difficult to determine the exact position of the pointer on the gauge.

　　This is an inexpensive solution, and in many cases is the standard configuration of the meter

　　It helps to extend the life of the pressure gauge by damping and lubricating the mechanical parts of the pressure gauge

　　Negative effects of Glycerine filled pressure gauge

　　Due to exposure to ultraviolet rays or extreme temperature changes, the glycerin of the Glycerine filled pressure gauge will change color (dark or yellow) over time

　　Standard glycerin really only works below 20 degrees Fahrenheit. Not recommended for cold environments

　　Leakage risk

　　Due to the expansion and contraction of the fluid caused by temperature changes (usually very small, around 1 PSI), the pressure will increase in the housing, which will affect the accuracy of the reading and cause the pointer to deviate from zero

　　A gas test gauge is also our product, welcome to consult and purchase.
