FY-12 Digital Thermo-Hygrometer with Square Thermometer, 1.5 meter

Description

The FY-12 is a miniature digital thermo-hygrometer designed for embedded panel mounting in incubators, refrigerators, aquariums, vehicles, and other environments where continuous temperature and humidity monitoring is required. It features a 1.5-meter external probe that allows the sensing elements to be placed in the measured environment while the LCD display remains accessible for reading .

The device is housed in a compact ABS plastic enclosure measuring approximately 48 × 28.6 × 15.2mm, with an embedded cutout size of 45 × 26mm for panel installation . The LCD displays both temperature and humidity simultaneously, with 0.1°C resolution and 1% RH resolution . The unit is powered by two LR44 button cells (included in some listings, not in others), and the sampling interval is approximately 10 seconds .

The FY-12 is available in black and white housing variants . The temperature range extends from -50°C to +70°C with ±1°C accuracy, and humidity from 10% to 99% RH with ±5% RH accuracy . The probe cable is 1.5 meters long, allowing flexible placement in incubators, terrariums, and aquariums .

Critical limitations: This is a low-cost, non-certified thermo-hygrometer intended for consumer and light commercial use. It is not a data-logging device and cannot connect to microcontrollers. The accuracy of ±1°C / ±5% RH is adequate for general monitoring but not for precision applications. User reports indicate that temperature readings may deviate by several degrees on some units, and humidity accuracy is unverified beyond the supplier specification .
