Applications:
The 8857 AZ Thermo Humidity Meter can measure the air temperature, surface temperature, humidity, wet bulb temperature, dew point temperature and temperature differential measurement. Its back light function could let user to operate the meter in the dark area easily.

The sensor of 8857 AZ Dew Point Temperature Meter is specially protected by gear damper device. While the sensor is retracted, the meter will not work. The sensor designed auto detects the air temperature and humidity if it is not retracted.

The 8857 AZ Psychrometer is a micro processor-based design. A must device for HVAC engineer use. No need to whirl the meter or refer to the chart. Easy to get wet bulb, dew point and surface temperature quickly. It also could be used as the best monitoring tool for the warehouse, work space, laboratories, basement, wine cellar or other controlled environment.

The 8857 AZ hygrometer IR Meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
