COMET SN252M – Ultra-thin Pt1000 temperature probe, -50 to +200 °C, Mini DIN connector

COMET SN252M – ultra-thin Pt1000 temperature probe Ø 3 mm, -50 to +200 °C, Class A (±0.15 + 0.002 t), MiniDin connector, Teflon cable 

The COMET SN252M is an ultra-thin Pt1000 temperature probe with a MiniDin connector – the perfect solution for extremely fast and precise temperature measurements in gases, liquids, or solids. With only 3 mm diameter and a length of 40 mm, the probe reacts lightning-fast to temperature changes (t0.5 up to 3 s, t0.9 up to 9 s), making it ideal for applications where conventional probes are too slow or too bulky. It is perfectly suited for measurements in narrow pipes, small vessels, airflows, laboratory equipment, medical technology, food processing, cryogenics, or any environment where minimal mass and maximum response speed are critical.

The Pt1000 sensing element (3850 ppm/°C, Class A) provides top-level accuracy: ±(0.15 + 0.002 × t) °C across the entire range of -50 to +200 °C. The 2-wire connection cable is made of Teflon-insulated, shielded wire (white) – chemically highly resistant, temperature-stable, and interference-proof. The MiniDin connector allows quick and secure connection to handheld thermometers, data loggers, or transmitters. The stainless steel housing (DIN 1.4301) is robust and corrosion-resistant. With IP67 protection, the probe is dustproof and waterproof – suitable for use even in humid or splash-prone environments.

The probe can be used universally as long as the measured medium is not chemically aggressive towards stainless steel 1.4301 and Teflon. The 1-meter cable length provides sufficient flexibility for easy installation. The high accuracy of Class A and the fast response time make it the first choice for calibrations, reference measurements, process control, or temperature monitoring with minimal delay. The probe comes with a 30-month warranty – COMET quality ensuring long-term measurement stability.
