A robust metal folding joint, a rubber-coated anti-slip surface, a  long and precise temperature sensor - and waterproof into the bargain!  The testo 104 food probe thermometer comes with a whole host of  practical features and benefits for use in the food industry.

The waterproof food thermometer for the food industry

Temperature  checks play a vital role in quality assurance, cold chain documentation  and hygiene regulations. The testo 104 food probe thermometer allows  you to carry out quick and easy spot checks during the production,  storage and processing of food. The food probe thermometer measures the  core temperature of liquid, semi-solid and viscous media.

The  thermometer`s especially thin but nonetheless rugged sensor tip leaves  virtually no trace when inserted. The thermometer can also measure the  core temperature of food when the probe has been folded out at an angle  of only 30°. This allows you to carry out reliable checks in  difficult-to-reach places.

The testo 104 is the only folding food  thermometer for the food industry which can be cleaned under running  water when you have finished measuring. The probe`s rugged metal joint  allows it to be folded away and kept in its protective case until you  need it again.

And here`s another practical feature: the testo 104  comes with a set of adhesive color strips which you can attach to the  individual meters when more than one of the same model are being used.

The  testo 104 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.
