Fever is one of the body's best-known warning signals, which should never be underestimated and should be monitored closely. The TM-61E Digital Thermometer is a certified medical device that can be used at three different body sites: oral (under the tongue), axillary (in the armpit) and rectal (in the anus). A result appears after just 30 seconds. The device automatically saves the last measured result. Acoustic signal tones indicate both the readiness for measurement and the end of measurement, as well as an increased temperature.
