When a quick reading is crucial, use the ADC® Adtemp™ 10 Second Hypothermia Thermometer. The world's first digital stick hypothermia thermometer can be used to take oral, rectal and auxiliary readings.
Ordered this because I liked the extended range. This little thing works great and is very easy to follow the instructions. I would recommend to anyone.
Bought this thermometer years ago for use in veterinary clinic. Helpful in hyper- & hypothermia cases. This thermometer gave temp. when $300 thermometers couldn't. Also, very fast reading, which is important with animals who don't understand the importance of holding still. Only thing I would recommend to the manufacturer is to make tip flexible so as to be more comfortable for the patient when used rectally. Great product, purchasing a second one for home/human use!
