The testo 103 is the smallest folding food thermometer in its class – making it perfect for carrying out spot checks in the food industry!


Product Description

The testo 103 food thermometer is just a little over 11 cm long, which makes it the smallest folding food temperature thermometer in its class. In fact, it’s so small it fits in any shirt or trouser pocket, so it’s always accompanying you whenever you need it. The probe can also be folded while not in use, to avoid any damages.

The testo 103 food thermometer – ideal for food safety inspections

The testo 103 food temperature 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 sleek food thermometer with 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.
