◆ Model: YD40 YD50 YD60 YD75 YD100 YD150
◆ The main body of the instrument is a general pressure gauge of various types and specifications, and the setting device on the window panel constitutes a positioning pressure gauge.
◆ The positioning pressure gauge can adjust the limited pressure gauge pointer as needed, and the upper and lower limits of the working pressure can be clearly calibrated to warn the on-site operators.
◆ The positioning pressure gauge is divided into single limit needle (red) and double limit needle (red and green), and its position is adjusted by the knob or lever set on the instrument window.
◆ Instrument use conditions: the same as the original type of pressure gauge.
◆ If it is necessary to make a shockproof type pressure gauge, it can be filled with glycerin or silicone oil.
