1.Product introduction



YGM421 was a high-end and high-precision temperature and humidity sensor, which could accurately measure the temperature and relative humidity of the environment. In addition, it could also accurately measure the dew point, the pressure of water and air, the mix proportion, absolute moisture, and heat enthrone. The new designed outer shell made the product have a higher level of protection and better response to the measuring needs in harsh environment. The products could be installed in three different ways: wall, pipe and body, which could be used in different measurement places.
