Beschreibung
Immersion resistance thermometer Pt100 Ø 3 × 300 mm is a handheld probe for precise temperature measurement in laboratory and process work. It uses a Pt100 sensor to DIN EN 60751 Class A in 4-wire technique for reliable, high-resolution readings with compatible meters. The stainless-steel sheathed stem measures 3 mm in diameter with a 300 mm nominal length and is permanently joined to a plastic handle. A fixed connection cable of 4 × 0,22 mm², insulated with Teflon/silicone and 2 m long, exits through a bend-protected gland. The stated application range is −90 °C to +350 °C. Termination is a Physics plug with 0,01 °C resolution, matching PHYSICS 100 and PHYSICS 300 instruments. This immersion resistance thermometer (assembly WT-MI-303-HG) from manufacturer Schneider suits deeper immersion in liquids and media where Class A accuracy, a longer sheath, and a ready handle-and-cable format are needed for controlled laboratory temperature monitoring.
This article is part of Temperature probes & sensors, in Temperature measurement.

Questions about Temperature probe, Pt100 Ø 3 x 300 mm
What is this article?
Temperature probe, Pt100 Ø 3 x 300 mm is the article on this page. Luminix Health distributes Schneider for laboratory use. It sits in Temperature probes & sensors, inside Temperature measurement, in Präzisionsinstrumente.
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.
