COMET 2091-250/E – Pt1000 Stick-in Probe -50 to +250 °C, ELKA Connector

COMET 2091-250/E – Pt1000 Stick-in / Penetration Probe -50 to +250 °C, Class A, ELKA Connector, Silicone Cable 

The COMET 2091-250/E is a robust Pt1000 stick-in / penetration probe with ELKA connector – specially designed for direct temperature measurement in soft or granular solids, soils, bulk materials, compost, silage, grains, liquids, and gases. With a measuring range from –50 to +250 °C and high Class A accuracy (±(0.15 + 0.002 × t) °C), it is perfect for agriculture, composting, storage monitoring, food processing, soil and environmental measurements, biogas applications, or industrial bulk material control – anywhere the probe can be easily inserted or immersed.

The measuring tip, made of corrosion-resistant stainless steel (DIN 1.4301 or 1.4571), is tapered and durable, suitable for demanding use in soil or bulk materials. The shielded silicone cable is flexible, heat-resistant, and chemically stable. The ELKA connector ensures a reliable, quick, and vibration-resistant connection to COMET measuring devices, transmitters, data loggers, or controllers. The IP67 housing provides dependable protection against dust and water jets – even under heavy outdoor use or in humid conditions.

The probe is maintenance-free, long-term stable, and available with a traceable calibration certificate (according to EN ISO/IEC 17025) – top quality for critical applications. Whether used in compost piles, grain silos, soil profiles, fermenters, or liquid tanks, the 2091-250/E stands out for its precision, durability, and ease of use. Simply insert, measure, done – no complex installation required.
