COMET 2021-150/0 Pt1000 Penetration Probe -30 to +150 °C

COMET 2021-150/0 Pt1000 Insertion Probe –30 to +150 °C

The COMET 2021‑150/0 (S 2021/150 Pt1000/3850) is a reliable 150 mm insertion temperature probe designed for everyday use in soft solids, bulk materials, pasty substances, as well as liquids and gases. Its sharp stainless steel tip penetrates easily into grain, flour, potatoes, fruit, meat, sausage, dough, compost, or soil, providing fast and accurate core temperature measurements within the range of –30 to +150 °C.

This probe is the standard choice in bakeries, butcher’s shops, commercial kitchens, silos, and agricultural storage facilities—everywhere HACCP‑compliant temperature monitoring is required. The high‑quality Class A Pt1000 sensing element ensures outstanding accuracy and long‑term stability, while the flexible, shielded 1 m silicone cable is heat‑ and cold‑resistant, providing reliable, interference‑free signals even in electromagnetically noisy environments.

The 2021‑150/0 is supplied without a connector, allowing the cable to be wired directly to COMET transmitters (T4411, P8510, H3531, etc.), data loggers, or any PLC with a Pt1000 input. The stainless steel probe is food‑grade and easy to clean.

Whether used for spot checks during goods inspection or for continuous measurement in a silo, this probe has been a trusted tool for quality managers and production supervisors for years.
