Type K temperature probe for immersion

AX 131

Type K temperature probes for immersion in gases and liquids , with -200 … +1150 °C range, Class 1 thermocouple, IP67 probe body, stainless steel stem.

Introduction

Temperature checks in liquids, gases and soft materials need a probe that reacts quickly and withstands daily professional handling. AX 131 probes cover immersion 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: Probes achieve T90 values below 2 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.

Accurate readings
Class 1 Type K thermocouple material supports reliable temperature measurement.
Fast checks
Type K is perfectfor fast measuring, e.g. Ø3 mm probes reach T90 below 2 s in water at 0.4 m/s.
Wide temperature span
Variants cover measuring ranges from -200 … +1150 °C.
Robust daily use
AISI 316 stainless steel stem and IP67 probe body support professional handling.
Type K standard connector
Standardized minature flat pin plug, e.g. for use with PRO 131 / 135 or ECO 130 / 130.2

Features

Immersion type

The family includes blunt immersion probes and needle-type insertion probes for use in gases and liquids.

Type K thermocouple

The sensor uses nickel-chromium / nickel-aluminum thermocouple material according to IEC 60584-1, highest accuracy class 1.

Stem configuration

Probe stems are available with Ø 3 mm diameter and standard lengths including 100 mm, 130 mm and 150 mm - others on request.

Cable and connection options

Probes can be supplied with silicone-coated thermocouple cable, coiled cable, miniature flat plug or loose ends with ferrules.

Mineral-insulated versions

Mineral-insulated probes use aluminum oxide powder inside the sensor tube for higher temperature resistance and limited bendability.

Calibration options

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).
