Product Description

The testo 103 food thermometer is just a little over 11 cm long, which makes it the smallest folding food probe thermometer in its class. It fact, it’s so small it fits in any shirt or trouser pocket, so it’s always with you when you need it. And because the probe can be folded away when it’s not in use, there’s no need to worry that it might break off or cause any harm or damage.

The testo 103 food thermometer – ideal for food safety inspections

The testo 103 food probe thermometer can be used everywhere where food is sold, stored or processed. It is ideal for checking incoming goods, catering services, canteens and commercial kitchens, as well as cold storage rooms and supermarkets, and for ensuring that temperatures are kept and quality and hygiene standards are met.

The food thermometer’s especially thin but nonetheless rugged sensor tip makes it ideal for carrying out spot checks on liquid and semi-solid media where it leaves virtually no trace.

It can also measure the core temperature of foodstuffs when the probe has been folded out at an angle of only 30°. This is particularly convenient – and often necessary – as it is not always possible to carry out measurements at an angle of 180° when checking food in certain storage spaces or when it is piled high in boxes or on display.

When you have finished carrying out your checks, simply fold the probe away and pop the thermometer back into your pocket until you need it again. The testo 103 food probe thermometer is not only HACCP compliant and EN 13485 certified but also splash water protected making it ideal for use in the food sector.

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
