Application :
Application of 8762 AZ Wet & Dry Bulb Hygrometer:
The 8762 AZ Psychrometer is designed with combined the traditional dry & wet bulb method and modern electronic circuit technology. There is no humidity sensor in the 8762 AZ Temperature Humidity Meter, so you don’t have to worry about condensation & dust scratch problems. The meter is powered by either 4pcs AAA batteries or a 5V adaptor. It is suggested to use adaptor when doing long time monitoring, since the built-in fan is high power consuming.
The 8762 AZ Wet & Dry Bulb Hygrometer has the relay function, which could transfer the signal to control the other equipment (ex: ventilation control, water spray…).
Memory recall function of 8762 AZ Psychrometer to review all 100 readings records. It could be your best tool for greenhouse or other high humidity, harsh and dust environment.

FAQ :
【FAQ of AZ 8762 Wet & Dry Bulb Humidity Meter with Relay Control】
Q1: Why choose a Wet & Dry Bulb meter over a regular humidity sensor?
A: Unlike standard sensors that fail in extreme conditions, the AZ 8762 uses wet/dry bulb technology. It remains accurate in high humidity, dusty, or chemically treated environments (like greenhouses) where condensation or fertilizers would typically damage other sensors.
Q2: How does the Relay Output function work for automation?
A: The AZ 8762 features a built-in relay that can be wired to external equipment. You can set high/low alarm limits to automatically trigger ventilation fans, humidifiers, or water sprays, making it a true environmental controller rather than just a monitor.
Q3: Does the AZ 8762 require frequent humidity calibration?
A: No. Because it relies on the physical principle of evaporation (psychrometry) rather than electrical capacitance, humidity self-calibration is not necessary. You only need to ensure the water tank is filled and the cotton wick is clean.
