Application
Application of 8857 AZ Temperature RH Meter:
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.

FAQ
【FAQ of AZ 8857 IR Hygrometer with Dew Point & Condensation Alert】
Q1: How does the AZ 8857 help prevent condensation and mold?
A: The AZ 8857 features a unique T1-T2 function that compares the actual surface temperature (T1) with the calculated dew point (T2). If the surface temperature is too close to the dew point, the device alerts you to the risk of moisture or mold formation before it becomes visible.
Q2: What makes the AZ 8857 reliable for long-term trend monitoring?
A: Reliability is driven by two core technologies:
High-Repeatability IR Sensing: Ensures consistent surface temperature readings over time, essential for identifying thermal trends.
Analog Capacitive Humidity Sensor: Unlike cheap digital sensors that drift quickly, our high-quality analog sensor offers superior stability and faster recovery from saturation, making it ideal for continuous industrial monitoring
Q3: Is the humidity sensor in the AZ 8857 protected for field use?
A: Absolutely. The AZ 8857 is designed with a rotatable protective cap and a geared mechanism. When not in use, the high-quality sensor can be retracted into the housing, protecting it from dust and physical impact during transport in toolboxes..
