Product Description 
 DYM3 aneroid barometer is based on a deformable element for sensing an atmospheric pressure measuring instrument. It is easy to carry, accurate measurement and a wide range of pressure measurement, easy to maintain, no mercury pollution, etc., widely used in the field of meteorology, military, aviation, marine, agriculture, surveying, geology, industrial and mining enterprises and scientific research become measurement atmospheric pressure of conventional instruments. 
 Working Principle 
 DYM3 aneroid barometer is an empty box group produces axial movement through the rod and the transmission mechanism driven pointer As induction originals, to indicate when the atmospheric pressure value with the changes in atmospheric pressure.
