COMET SN199 Pt1000TR160/0 Submersible Probe IP67 -30 to +80 °C

COMET SN199 Pt1000TR160/0 Immersion Probe IP67 -30 to +80 °C

The COMET SN199 (Pt1000TR160/0) is a particularly affordable yet fully IP67 waterproof immersion and multipurpose temperature probe designed for daily use in non-aggressive media. With its compact polyamide housing (only 20 mm × Ø5.7 mm) and shielded 1-meter PVC cable, it fits anywhere and provides reliable measurements from –30 to +80 °C.

Whether in heating systems, hot water tanks, HVAC ducts, aquariums, greenhouses, cold rooms, or for simple water and process monitoring, the SN199 is the ideal economy solution for equipping multiple measuring points cost-effectively—without compromising proven COMET quality.

The Pt1000 sensing element meets Class A (3850 ppm/°C) specifications and offers an accuracy of ±(0.3 + 0.005 × |t|) °C—more than sufficient for most standard applications. The probe is fully sealed and easily withstands long-term moisture, condensation, and even brief submersion without failure.

Delivered without connector, allowing direct cabling to COMET transmitters, data loggers, or any PLC equipped with a Pt1000 input.
