Description
High-precision immersion/penetration probe with Pt100 sensor enables accurate temperature measurement across a wide working range from −80 °C to +300 °C. When paired with a compatible Testo temperature instrument such as the testo 735, the resulting system accuracy is high enough for the assembly to serve as a working standard. The probe is therefore particularly suitable for quality-assurance tasks, calibration services and laboratory applications where traceable, repeatable readings are essential. Its immersion/penetration design allows reliable contact with liquids, semi-solids and process media, supporting both routine monitoring and reference measurements. Offered as a single unit from manufacturer Testo, the sensor integrates into existing Testo measuring chains without additional adapters for standard configurations. Robust construction and the established Pt100 sensing principle ensure stable long-term performance under typical laboratory and industrial conditions. This high-precision probe is a practical choice wherever elevated measurement certainty is required for process control, method validation or instrument verification.

Questions about Immersion/penetration probe, Pt100 ,, high-precision
What is this article?
Immersion/penetration probe, Pt100 ,, high-precision 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.
