The Testo 105 one hand thermometer with frozen goods measuring tip is ideally suited to the measurement of the core temperature in deep-frozen goods, such as meat. You can order additional measuring tips separately for measurements in semi-solid media (meat, cheese, jellies). The practical one-hand operation, compact size and illuminated display make every day practical work easier. Both an acoustic and an optical alarm reliably warn of any exceeding/undershooting of the freely adjustable limit values. The belt holder and wall bracket ensure safe storage - even on the move. This means the thermometer is always ready to hand. Good to know: thanks to a water-repellent surface, the penetration thermometer can also be cleaned under running water – particularly hygienic in accordance with protection class IP65. The Testo 105 is tested for the food sector according to EN 13485 and certified by HACCP International.
