Economic set for infrared and core temperature measurement
The infrared temperature measuring instrument testo 831 records surface temperature without contact. The measurement spot diameter of this practical infrared thermometer is only 3.6 cm at a distance of 1 m. The advantage: even smaller objects, such as yoghurt pots, can be measured almost in passing. The 2-point laser marker shows the measurement spot exactly. You avoid measurement errors.

The core thermometer testo 106 with its thin, robust measuring tip is exceptionally well-suited to making fast core temperature checks on sensitive foodstuffs. It leaves hardly visible puncture holes.
Both helpers are small, handy and always ready to hand.
