BT-3 Temperature + Humidity Indoor / Outdoor 2M External Sensor🌡️ Elitech BT-3 Digital Thermometer & Hygrometer
The Elitech BT-3 Digital Thermometer and Hygrometer is a practical environmental monitoring instrument designed to display indoor temperature, outdoor temperature and indoor relative humidity.
Equipped with an internal temperature and humidity sensor together with a 2-metre external temperature sensor, the BT-3 allows users to monitor two different temperature locations from one convenient digital display.
Additional functions including MAX/MIN memory, comfort display, °C/°F selection, clock and 12/24-hour display make it suitable for refrigeration, storage areas, offices, homes and other temperature-sensitive environments.
📊 3 Measurements on One Display
🌡️ Indoor Temperature
The built-in sensor monitors the temperature around the BT-3 main display unit.❄️ External Temperature
The supplied wired external sensor measures temperature at a second location over a much wider temperature range.💧 Indoor Humidity
The built-in humidity sensor displays relative humidity at the location of the main BT-3 unit.The external probe measures temperature only. Humidity measurement is taken by the sensor inside the BT-3 main display unit.

• The built-in sensor measures indoor temperature and humidity.
• The external 2 m wired sensor measures temperature only.
• Position the main unit where air can circulate around the sensor.
• Avoid placing the main unit directly beside strong heat sources or direct sunlight when representative room readings are required.
• For critical cold-chain or compliance monitoring, use monitoring equipment specifically rated and calibrated for the required application.
