Testo 105 Food Thermometer Set – Standard, Frozen Food and Long Measuring Tips, −50…+275 °C, IP65, Aluminum Case (0563 1052)

Testo 105 set (product code 0563 1052) offers a one-handed food thermometer together with three interchangeable measuring tips for measuring core temperature in semi-solid, frozen and liquid products: a standard tip for semi-solid media, a frozen food tip for frozen products and a long measuring tip for liquids. The instrument measures in the range −50 … +275 °C; in the range −20 … +100 °C the accuracy is ±0.5 °C. It gives an audible and visual alarm when either of two freely adjustable limit values is exceeded. Its IP65-protected housing can be cleaned under running water. It is used in food production, goods receipt inspection, gastronomy, large kitchens, cold rooms and supermarkets; according to Testo it is EN 13485 certified and HACCP International approved.

Core Temperature in Semi-Solid, Frozen and Liquid Products

The measuring tips are easily attached to and removed from the instrument. The standard tip is inserted into semi-solid products such as meat, cheese and jelly to measure the internal temperature; the frozen food tip is screwed into deep-frozen products for temperature checks; the long tip is suitable for measurements in liquid media. The response time is approximately 10 seconds with the standard and long tips and 15 seconds with the frozen food tip (approximately 60 seconds in frozen meat).

The illuminated display lights up for 5 seconds each time a button is pressed; it also comes on when the alarm limits are exceeded. With Auto Hold on, if the reading changes by less than 0.2 °C over the selected period (5, 10, 15 or 20 seconds), the value is fixed automatically; the value can also be frozen manually. The unit of measurement is set to °C or °F, and the instrument switches off automatically if not used for 10 minutes. The belt/wall mounting kit allows the instrument to be kept safely in the field and at the workplace, and all equipment is carried in the aluminum case.

Technician Tips

• Choose the right tip: use the standard tip for semi-solid products such as meat, cheese and jelly, the screw-in frozen food tip for deep-frozen products, and the long tip for liquids.
• Observe the immersion depth: for an accurate result, reach a depth of at least 35 mm with the standard and long tips and at least 50 mm with the frozen food tip. Continuous contact with food applies to the section from the probe tip up to 1 cm before the handle.
• Wait with frozen products: the response time of the frozen food tip is 15 seconds; in frozen meat it takes approximately 60 seconds for the value to stabilize, so do not end the measurement before this time.
• Set the Auto Hold time to suit your work: with Auto Hold on, the stability time required to fix the value can be selected as 5, 10, 15 or 20 seconds. If the value changes by less than 0.2 °C during this time, the instrument fixes the value.
• Keep the tip attached when washing: IP65 protection applies when the measuring tip is attached to the instrument; do not remove the tip when cleaning the housing under running water. For thermometers used under EN 13485, annual checking and calibration according to EN 13486 is recommended.
