Description
testo 104 is a robust foldable penetration thermometer designed for rapid core-temperature checks on liquid, semi-solid and viscous media in food production, storage and processing. Covering a measuring range from −50 °C to 250 °C with a T99 response time of 10 s, the instrument delivers fast spot readings while its slim yet sturdy sensor tip leaves only discreet puncture marks. Full functionality is available from a fold-out angle of 30°, enabling reliable measurements even in hard-to-reach locations. A durable metal hinge and rubberised grip ensure secure handling, and after use the waterproof housing can be rinsed under running water. The probe folds safely into the instrument body between measurements; colour strips supplied with the unit allow clear identification when several devices are in service. Certified to EN 13485, HACCP-compliant and rated IP65, the single-channel battery-powered thermometer from manufacturer Testo is purpose-built for hygiene-critical food environments and cold-chain documentation.

Questions about testo 104 - Waterproof food thermometer
What is this article?
testo 104 - Waterproof food 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 précision.
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.
