                  LD-500 type dew point instrument
                  One, overview
                  LD-500 type dew point instrument of imported impedance type humidity sensor, has the advantages of fast reaction rate, stable performance, corrosion resistance. Anti condensation from the new calibration technology. For a variety of industrial processes have strict control of occasions to the moisture content.
                  Two, the main use of
                  • compressed gas, natural gas, chemical raw material gas
                  • plastic drying equipment
                  Gas, generating hydrogen cooling gas high voltage insulation, power system
                  • drying industry
                  • other strict process control for trace water
                  Three.
                  • import impedance type humidity sensor
                  • large screen LCD display, Chinese menu function selection
                  Signal transmitters, with a new type of microprocessor, the operation is very convenient
                  • dew point temperature and water ppm value display, no table lookup calculation
                  • automatic data storage, paperless recorder with function
                  • measuring point alarm set
                  • communication port RS232
