General
Diameter	4 mm
Thermocouple type	K

The Chauvin Arnoux SK3 is a semi-rigid K-type thermocouple probe designed for surface temperature measurement in the range of -50 °C to +1000 °C. The probe is suitable for applications requiring a certain degree of flexibility without significant deformation of the probe structure. With a diameter of 4 mm and a total length of 50 cm, it offers a balanced combination of precision and ease of handling. The probe is designed for use in industrial and technical environments where reliable temperature measurement on surfaces or in easily accessible areas is required.

Applications
The SK3 is typically used in manufacturing, machine building, process monitoring, or maintenance work where non-invasive surface temperature measurement is required. The probe can be used, for example, to monitor heaters, motors, electrical components, or other thermally stressed parts. The semi-rigid design allows for precise positioning without being fully rigid, which is advantageous during installation or when contacting uneven surfaces.

Features and Equipment in Detail
The probe has a measurement range of -50 °C to +1000 °C, making it suitable for a wide range of applications, from cool to high-temperature environments. The response time is 6 seconds, enabling a quick reaction to temperature changes. The probe is slightly deformable, meaning it can be bent slightly without losing functionality. The 4 mm diameter and 50 cm length ensure good handling and allow use in tight or hard-to-reach areas.

Technology Explained Simply
The SK3 is based on K-type thermocouple technology, which measures the thermoelectric voltage generated between two different metals. This technology is widely used in industrial measurement technology due to its robustness, cost-effectiveness, and suitability for a wide temperature range. The probe generates an electrical signal proportional to the measured temperature and can be connected to suitable measuring instruments to display or record the temperature. The semi-rigid construction ensures the probe maintains its shape but can be adjusted as needed to ensure secure contact with the measurement surface.

Compatibility and Accessories
The SK3 is designed for use with measuring instruments that support K-type thermocouples. Exact compatibility depends on the connection options and signal processing of the respective device. The probe is offered as standalone measurement accessory and requires no additional components for operation.

Installation and Mounting
Mounting of the SK3 is done by direct contact with the surface to be measured. The semi-rigid design allows for easy positioning, with the probe placed so that it fully contacts the surface. No additional mounting aids or tools are required. The probe can be directly connected to the measuring instrument, with the connection interface matching the respective device. Installation therefore requires no additional preparation or mounting steps.

Operational Advantages
The SK3 provides reliable and fast temperature measurement with a wide measurement range. The semi-rigid design allows for flexible handling without compromising measurement accuracy. The short response time of 6 seconds ensures timely reaction to temperature changes, which is beneficial in dynamic processes. The probe is suitable for industrial environments where robust and precise measurement is required. K-type thermocouple technology is widely used and supported by many measuring instruments, increasing compatibility.
