Overview
A basic digital thermometer built for taking a cat's or dog's temperature at home, with a 20 second read time and a claimed range of 95 to 107 degrees Fahrenheit. It ships in a clear storage case with one spare battery included.
This is a single use style probe thermometer rather than a rectal-safe flexible design, so gentle, careful handling matters more than with a vet-clinic unit. The orange color and hard plastic housing are meant for quick identification and easy wipe-down between uses.
- 95 to 107 degree Fahrenheit range
- 0.1 degree Celsius resolution
- Two LR41 batteries required
- 12 month manufacturer warranty
Who it's for
Owners who want a cheap way to check whether a lethargic dog or cat is running a fever before deciding whether a vet visit is needed. Not a substitute for a veterinary thermometer if you need clinical accuracy or use it daily.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reads in about 20 seconds
- Waterproof tip for easy cleanup
- Comes with a spare battery and case
- No rectal safety guard mentioned
- Battery type is a small, less common LR41 cell
Performance notes
The listed 20 second response time and 0.1 degree Celsius resolution point to a standard digital probe sensor, powered by two LR41 button cells. Waterproofing lets the tip be rinsed off after use, and the included storage box keeps it separate from other household items.
