Hygrometer w/ relay

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 an adaptor when doing long-time monitoring since the built-in fan is highly power-consuming.

The 8762 AZ Wet & Dry Bulb Hygrometer has a 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 a greenhouse or other high-humidity, harsh, and dusty environment.
