The Greisinger GMF 250 is a NiCr-Ni (type K) Magnetic Surface Probe for surface temperature measurements. The GMF 250 is used exclusively for magnetic materials, because of its self-adhesive measuring sensor with Cu-plate. The probe is not appropriate for use at induction furnaces, etc. The thermocouple consists of two electric lines made of different materials (NiCr and Ni). The measuring principle of temperature measurement with thermocouples is based on the existence of thermo voltage when two wires made of different materials are connected. The probe is delivered with ready-to-use, thermo voltage-free miniature flat-pin plug NST1200. Applications; Ideal for use in kitchens, food plants or the HVAC industry. * NiCr-Ni-probe (type K) * Self-adhesive on magnetic surfaces (reinforced design) * Resilient measuring sensor * Thermocouples wires: 1m Teflon insulated twisted wires (max. 250°C) * Wire type: very flexible, diameter approx. 1.0 mm * Measuring point: Magnetic, resilient measuring sensor with Cu-plate Ø 5mm * Connection: Miniature flat-pin plug NST1200 * Manufacturer's part: Greisinger GMF 200 https://elecena.pl/product/27750415/greisinger-gmf-250-type-k-gmf-250-magnetic-surface-sensor-mini-thermocouple 2025-01-24 https://elecena.pl/product/27750415/greisinger-gmf-250-type-k-gmf-250-magnetic-surface-sensor-mini-thermocouple 2026-07-11
