Description
The FY-10 is a miniature digital thermometer designed for embedded panel mounting in refrigerators, freezers, display cabinets, incubators, and other equipment where continuous temperature monitoring is required. It features a 1-meter external NTC probe (10KΩ, B=3435) that allows the sensing element 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 × 15mm, with an embedded cutout size of 46 × 27mm for panel installation . The LCD displays temperature with 0.1°C resolution, and the unit is powered by two LR44 button cells (not included), providing approximately one year of operation under normal use .
The FY-10 is available in Celsius-only and Fahrenheit-display versions , and the measurement range extends from -50°C to 110°C . When the temperature falls below -50°C, the display shows “LO°C”; above 110°C, it shows “HI°C” . The sensor response delay is approximately 1.5–2 seconds .
Critical limitations: This is a low-cost, non-certified thermometer intended for consumer and light commercial use. It is not a data-logging device and cannot connect to microcontrollers or transmit data. The accuracy of ±1°C is adequate for general monitoring but not for precision applications. The battery is not included, and the probe is not waterproof on all variants—verify with your supplier.
