COMET SN104M – Pt1000 Temperature Probe -50 to +200 °C, Mini DIN Connector

COMET SN104M – Pt1000 Temperature Probe -50 to +200 °C (temporarily -80 °C static), Class A, MiniDin Connector, Silicone Cable, IP67 

The COMET SN104M is a versatile Pt1000 temperature probe with a MiniDin connector – the ideal solution for precise and durable temperature measurement in gases, liquids, and solids. With a measuring range from -50 to +200 °C (short-term up to -80 °C at static cable position) and high Class A accuracy, it is perfectly suited for HVAC systems, building automation, warehouse and cold storage monitoring, machinery, laboratories, environmental technology, or any application requiring a waterproof, chemically resistant, and long-term stable probe.

The Pt1000 sensing element (3850 ppm/°C, Class A) provides high precision: ±(0.15 + 0.002 × t) °C across the entire range. The stainless steel sheath DIN 1.4301 (diameter 5.7 ± 0.1 mm, length 40 mm) is corrosion‑resistant and designed for direct contact with various media. The shielded silicone cable is highly flexible, heat‑resistant, and chemically strong – ideal for demanding environments. The MiniDin connector enables safe and quick connection to COMET measuring devices, data loggers, transmitters, or controllers. The IP67 protection ensures the probe is completely dust‑ and waterproof – making it suitable even for humid or splash‑exposed environments.

The probe can be used universally as long as the medium is not chemically aggressive to stainless steel 1.4301 or silicone. Its fast response time (t0.5 < 7 s in flowing water) provides direct and reliable readings. With a 30‑month warranty and proven COMET quality, it offers excellent value for money. Whether for retrofit, replacement, or new installation – the SN104M is the reliable choice for both standard and demanding Pt1000 applications.
