Embedded Digital Hygrometer Temperature and Humidity Meter FY-12 with Wired Probe

FY-12 Embedded Digital Hygrometer & Thermometer — LED Display, Wired Probe

The FY-12 is a compact panel-mount digital hygrometer and thermometer designed for embedding into enclosures, incubators, terrariums, humidors, storage cabinets, and environmental monitoring equipment. The wired probe separates the sensing element from the display unit, allowing the probe to be placed in the measurement zone while the LED display remains visible on the panel exterior.
