Temperature checks in liquids, gases and soft materials need a probe that reacts quickly and withstands daily professional handling. AX 131-I probes cover immersion and insertion tasks with Type K thermocouple technology, giving users a practical choice for food-related contact, field checks and temperature measurements with compatible handheld instruments.
The stainless steel stem resists corrosion and temperature exposure, while the ergonomic handle is rated for operating temperatures up to 120 °C. With Class 1 thermocouple material and a measuring range up to -200 … +1150 °C, the probe family supports accurate readings across demanding temperature tasks.
Fast response helps reduce waiting time during checks: Ø 1.5 mm probes achieve T90 values below 1 s in water at 0.4 m/s, while Ø 3 mm variants are suited to more robust use. IP67 protection, except at the connector, and easy-clean construction make the probes a dependable choice for regular professional measurement work.
The family includes robust Ø3 mm cold formed prbes and needle-type insertion probes for use in gases, liquids and soft materials.
The sensor uses nickel-chromium / nickel-aluminum thermocouple material according to IEC 60584-1, highest accuracy class 1.
Probe stems are available with Ø 1.5 mm or Ø 3 mm diameter and standard lengths including 100 mm, 130 mm and 150 mm - others on request.
Probes can be supplied with silicone-coated thermocouple cable, coiled cable, miniature flat plug or loose ends with ferrules.
Probes can be supplied with ISO 9001 or DAkkS-/ACCREDIA accredited ISO/IEC 17025 calibration when combined with a suitable display instrument (EG PRO 131 /135 or ECO 130).
