Frequently Asked Questions
Q: Can I use a meat thermometer for water?
A: Yes, as long as it’s rated waterproof (like the BOMATA T101), it’s safe for liquids including water, milk, and soups.
Q: How often should I calibrate my thermometer?
A: For most home users, once a year is sufficient. Use the ice-water test (should read 32°F) to check accuracy.
Q: Are floating pool thermometers accurate?
A: They’re generally within 2–3°F of actual temperature good enough for recreational use, but not for scientific applications.
Q: Do digital thermometers work in hot tubs?
A: Only if they’re rated for high temperatures (above 120°F) and fully waterproof. The Lonicera and BOMATA models are excellent choices.
Q: What’s the difference between IPX6 and IPX7?
A: IPX6 resists strong water jets; IPX7 can be submerged in up to 1 meter of water for 30 minutes making it better for baths and spills.
