Description
testo 103 penetration thermometer is a compact folding core-temperature instrument for food control, storage, laboratory, catering and retail checks. At only about 11 cm when folded, it fits a shirt or trouser pocket and stays ready for use thanks to its folding mechanism. The narrow yet robust sensor tip leaves a discreet puncture mark in liquid and semi-solid media, making it practical for goods-in, warehouse and display sampling. Measurement starts reliably from a fold-out angle of 30°, so core temperature can be taken even when a full 180° opening is not possible in cartons or tight storage. The measuring range covers −30 °C to 220 °C on a single channel, with a T99 response of 10 s. Dimensions are approximately 189 mm × 19 mm × 35 mm and net weight is 0,12 kg. HACCP-compliant and certified to EN 13485, with splash protection to IP55, the instrument from manufacturer Testo is built for everyday hygiene and quality temperature checks wherever food is sold, stored or processed.

Questions about testo 103 - Penetration thermometer
What is this article?
testo 103 - Penetration thermometer is the article on this page. Luminix Health distributes Testo for laboratory use. It sits in Temperature probes & sensors, inside Temperature measurement, in Instruments de laboratoire.
A temperature probe is the sensor, Pt100, thermocouple or thermistor, that a meter or a logger reads. The probe, not the display, is what is calibrated. The sheath material and the response time matter in a liquid versus a block.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
