Key Benefits and Applications

• Fast, confident readings: A rapid time constant delivers quick stabilisation, reducing waiting time between points and increasing productivity in test routes.
• Purpose‑built for air and gases: The probe geometry is tailored for environment measurements, ensuring reliable results in ducts, chambers, cleanrooms, HVAC balancing and industrial oven mapping.
• High accuracy by design: Built on Type K thermocouple technology with strict conformity to international accuracy classes, ideal for audits and quality documentation.
• Rugged for daily use: Durable construction stands up to repetitive measurements in production lines, field services and lab routines.
• Universal thermocouple ecosystem: Works with instrumentation that accepts Type K sensors, simplifying fleet management and reducing spares complexity.
• Versatile across industries: From pharma and food to automotive, electronics and general manufacturing, it supports environmental chamber checks, airflow studies and process verification.

Featured technical specifications

• Sensor principle: Type K thermocouple based on Chromel–Alumel for wide industrial applicability and robustness.
• Probe category: Environment and air temperature measurements, ideal for gases and ambient monitoring rather than immersion or surface contact.
• Maximum measurable temperature: Up to 400 °C, suitable for most environmental and process air applications.
• Time constant: Typical τ0.63 around 4 seconds in moving air, supporting swift point‑to‑point measurements.
• Accuracy class: Conforms to IEC 60584‑2 Class 1 for Type K thermocouples, with limits of error defined as ±1.5 °C or ±0.004·|t| (whichever is greater) within the valid range.
• Dimensions: Slim stem approximately Ø 4 mm with 180 mm length to minimise airflow disturbance and ease access inside ducts and chambers.
• Typical use range: Designed for ambient and process air tasks spanning room conditions up to high‑temperature environments within the specified maximum.
