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 backlight function could let the user operate the meter in a dark area easily.
The sensor of the 8857 AZ Dew Point Temperature Meter is specially protected by a 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 microprocessor-based design. A must device for HVAC engineer use. No need to whirl the meter or refer to the chart. Easy to get the wet bulb, dew point, and surface temperature quickly. It also could be used as the best monitoring tool for the warehouse, workspace, laboratories, basement, wine cellar, or another controlled environment.
The 8857 AZ hygrometer IR Meter was designed and manufactured by AZ Instrument, a well-experienced manufacturer of Environmental Measuring instruments.
