II. Product Features

High-Temperature Resistant Flexible Cable: Fiberglass insulation allows long-term use at up to 400°C; easily bent, threaded through narrow gaps, box openings, or door cracks for measurement

Ultra-Thin Probe: 1.5 mm ultra-fine tip ensures extremely fast air temperature response

Universal K-Type Connector: Compatible with most testo handheld thermometers, temperature-humidity data loggers, and anemometers (e.g., testo 108/922/925/440/175/176 series)

Lightweight design for convenient handheld inspection in the field

III. Typical Applications

Temperature monitoring of air ducts, ovens, aging chambers, and environmental chambers

Measuring temperatures in tight spaces such as HVAC ducts, ovens, and heat treatment equipment

Temperature measurement in confined industrial cavities, interlayers, door gaps, and narrow passages

Quick spot checks of process temperatures in laboratories and production lines

IV. Usage Limitations

Suitable only for air and gas temperature measurements; not recommended for direct immersion into liquids or highly corrosive media

Long-term operating temperature must not exceed 400°C continuously

Fiberglass sheath has moderate abrasion resistance; avoid contact with sharp or hard objects that may scratch the cable
