Details 
 WSSN thermometer is a series of seismic measurements in low-temperature field instrumentation. It can directly measure a variety of production processes -80 ℃ ~ +500 ℃ within the liquid, vapor, gas and environmental sites, and vibration of harsh temperatures. Thermometer from the seismic design principles and structure of a waterproof, corrosion-resistant, shock-resistant, intuitive, easy to read, victims of mercury-free, durable, etc., thermometers are widely used in seismic oil, chemicals, machinery, shipbuilding, power generation, textile, printing and dyeing and other industrial and scientific research departments. 

 Key Features 
 Site show that the temperature, easy and intuitive; safe, reliable, long life; 
 Variety of structural forms, which can meet different requirements. Mercury harm, easy to read, strong seismic. 
 Stainless steel protection tubes for the 1Gr18Ni9Ti two titanium and molybdenum, pressure, anti-corrosion ability. 
 Pulling thermometer short-term maintenance or replacement without stopping the movement. 
 Integrated with axial, radial-type, 135 o type, universal type and other variety, adapted to a variety of on-site installation. 
 Work 
 Earthquake resistance thermometer is based around the ring is made of bent-shaped bimetal composition. When one end of thermal expansion, driven pointer rotation, working instrument will show the temperature value to be, and to prevent environmental vibration silicone oil filling in the internal thermometer or thermometer part and measuring part of the separation to achieve the seismic effect.
