The FY-12 Mini Digital Hygrometer Thermometer is a highly accurate, compact environmental sensor featuring an embedded LCD display. Designed for absolute simplicity, it provides simultaneous dual readouts of temperature (in Celsius) and relative humidity (% RH). Its sleek rectangular profile is purpose-built for panel mounting, making it incredibly popular for custom project enclosures, reptile enclosures, cigar humidors, egg incubators, and smart home setups.
Instant Digital Readout: Crisp, clear LCD screen displays temperature and humidity side-by-side without needing any programming.
Panel-Mount Design: Equipped with side clips for clean, flush mounting into square cutouts on acrylic, plastic, or wood panels.
High Reliability: Low power consumption design allows a single pair of LR44 batteries to keep the unit running continuously for months.
Ultra-Compact Footprint: Miniature form factor easily slips into tight spaces where space-saving monitoring is critical.
