QA:
Q: Can I install this thermometer on a wall or wooden surface?
A: No. The WT-1 is specifically designed for transparent surfaces like glass or acrylic. It must be viewed from the opposite side to read the temperature correctly.
Q: How do I install it?
A: Simply peel off the backing of the included adhesive pad and stick the unit onto a clean, transparent surface. No tools or drilling are needed.
Q: Can it be used in cold weather?
A: Yes, it operates reliably from -25℃ to +70℃ (-13℉ to 158℉). For temperatures below -10℃ (14℉), we recommend using lithium AAA batteries, as they perform better than alkaline batteries in extreme cold.
What’s in the box?
2 x WT-1 Thermometers
2 x AAA Batteries
