This wood thermometer is a classic liquid-filled analog temperature measuring instrument. Encased in polished natural wood panel, it is built with a glass capillary tube containing red-colored indicator liquid, supporting dual-scale display of Celsius and Fahrenheit.
Working on the physical principle of liquid thermal expansion and contraction, it requires no batteries, electricity or extra power supply, which brings low-maintenance and long-term stable performance. Designed for wall-hanging installation, it is lightweight and easy to mount.
Suitable for a wide range of scenarios: household indoor spaces, greenhouses, farm barns, storage warehouses, workshops and animal husbandry sites. It offers reliable ambient air temperature reference. The metal clip at the bottom protects the glass tube and ensures structural stability.
Not intended for laboratory high-precision measurement or liquid immersion measurement. Avoid direct sunlight and heat sources to guarantee accurate readings.
Measuring Range: -40℃ ~ +50℃ (-40℉ ~ 120℉) Material: Wood panel, glass liquid tube, metal hanging clip
Important Notes
Do not drop, strike or impact the thermometer to avoid glass tube breakage.
Keep away from direct sunlight, heaters, air-condition outlets and other heat sources, otherwise inaccurate readings will occur.
It is only for air temperature measurement. Do not immerse the whole unit into water.
Keep out of children's reach. Broken glass may cause injury.
If liquid column separates, place it in cool area for natural reunion. Never heat it manually.
For general temperature reference only, not for high-precision laboratory applications.
