COMET Pt1000 Immersion Probe -190 to +150 °C for Cryogenics & Deep Freezing, RCA Connector

COMET SN239C – Pt1000 Immersion Probe –190 to +150 °C for Cryogenic & Deep-Freezing Applications, CINCH Connector 

The COMET SN239C (Pt1000TR125/C) is a professional cryogenic immersion probe with a CINCH connector, designed for extreme low‑temperature applications. With a wide measuring range from –190 to +150 °C, it is perfectly suited for liquid nitrogen, deep‑freezing, cryogenics, laboratories, cold‑chain monitoring, LNG handling, and process cooling – anywhere precise temperature measurement below –100 °C is required.

The Class B Pt1000 sensor (±0.3 + 0.005 × |t| °C) ensures reliable accuracy even at very low temperatures. The robust stainless‑steel housing (DIN 1.4571) offers excellent corrosion resistance and durability. The shielded PVC cable (standard 1 m) remains flexible and operational across the entire temperature range. The CINCH connector provides a quick, secure connection to COMET transmitters, data loggers, or any Pt1000 input device.

The probe is fully sealed to IP67 – perfect for condensate, splashing water, or immersion in cryogenic liquids. Easy to mount and immediately ready for use, it is the ideal solution for research, industry, and medical applications requiring reliable temperature measurement under extreme cold conditions.
