+The parts contacting with the liquid and the case are made of stain less steel so that they are excellent in anti-corrosion and environ-mental resistance.
+By equipping a blowout disk, the effect of temperature change on accuracy is reduced, and breakage of glass is prevented in case the Bourdon tube bursts.
+To indicate the working pressure gauges with 60 DIA. and 75 DIA. are provided with a safety mark(green mark) as an option which can be set by an arrow.
*In case of selecting pressure gauge, choose the pressure range which can be used in between 30-65% of full scale, so that the gauge can give its full capacity.
