Simple. Effective. Reliable. That's everything you need a professional thermometer - and that's exactly what you get with the Hygiplas Easytemp thermometer. The casing is already strong and robust, but comes with a handy removable wrist strap to prevent accidental damage from drops or bangs.. An auto on/off function conserves power to cut down on the need for regular battery replacements, and switching between °C and °F is as simple as pushing a button.
