Product Description

Testo 103 – The smallest folding
thermometer in its class


  • Ideally suited for applications in the food sector
  • Easy to operate
  • Handy and small – fits in any trouser or jacket pocket
  • Robust probe with narrow measurement tip
  • Hygienic and easy-to-clean measurement tip
  • Splash-proof according to IP55
  • Certified according to EN 13485


At a length of 11 cm, the testo 103 is the smallest folding
thermometer in its class.
It hardly takes up any space, so you can simply stow it in your breast or trouser pocket. That way, it is always quickly available and close to hand.
The small folding thermometer is immediately ready to measure
after folding out to an angle of greater than 30°, and is
therefore flexible in its application.
After measurement, the probe can simply be folded away and stored safely until the next measurement.

The folding thermometer testo 103 is conform to HACCP
and EN 13485.
Its narrow measurement tip leaves only small punctures in the foodstuffs, making it optimally suitable for spot checks – for example in production, storage and processing, in gastronomy, in supermarket
chains, in food retail or in industry
