WSS-411 Bimetal Thermometer Gauge is a field detection instrument used for measuring medium and low temperatures of steam turbine bearings, which can be used to directly measure the temperature of liquefied and gas. Compared with glass mercury thermometers, it has the advantages of being mercury free, easy to read, and durable. Its protective tube, joint, locking bolt, etc. are all made of 1Cr18Ni9Ti material. The case is made of aluminum plate stretch molding and has a black electrophoretic treatment on the cutting surface. The cover and case adopt a circular double-layer rubber ring screw sealing locking structure, so the overall waterproof and anti-corrosion performance of the instrument is good. The radial type instrument adopts a curved pipe structure, with a novel, lightweight, and unique appearance.
