The Chauvin Arnoux TK2002 is a compact, digital thermometer with two inputs for K-thermocouples, designed for precise temperature measurements in demanding environments. It enables both single-point measurements and the determination of temperature differences between two measurement points. The device is suitable for industrial applications as well as outdoor use, as it features an IP65 protection rating, making it dust- and water-tight. The measurement range extends from -50 °C to +1000 °C, with accuracy in the range of 0 °C to +1000 °C being ± 1.5 % + 0.5 °C. In the range of -50 °C to 0 °C, accuracy is ± 1 °C. Resolution varies depending on the measurement range between 0.1 °C and 1 °C. The thermometer includes a HOLD function, allowing the current measurement value to be held, and displays readings in °C. Dimensions are 163 x 63 x 37.5 mm, and weight is 200 g.

Applications
This thermometer is suitable for a wide range of applications in industry, maintenance work, manufacturing technology, or outdoor testing. The IP65 protection rating makes it robust against dust, splashing water, and light rain, making it suitable for use in environments with high mechanical and climatic stress. The ability to measure temperature differences is particularly useful for monitoring heat transfer processes, testing heating or cooling components, or analyzing temperature gradients in machines and systems.

Functions and Features in Detail
The device features two independent inputs for K-thermocouples, enabling simultaneous measurement of two different temperature points. The HOLD function ensures that a measured value remains displayed even during movement or brief interruption of the measurement. Display is exclusively in degrees Celsius. Measurement accuracy is constant at ± 1 °C in the lower range (below 0 °C), while in the upper range (from 0 °C onwards), it is determined by a percentage of the measured value plus a constant offset, ensuring high reliability at high temperatures.

Technical Explanation
K-thermocouples are temperature sensors based on the Seebeck effect, where a voltage is generated when two different metals are joined at a point and heated to different temperatures. The thermometer converts this voltage into a temperature reading. The IP65 protection rating means the device is fully protected against dust and resistant to water splashing from any direction, making it suitable for use in humid or dusty environments. Resolution of 0.1 °C to 1 °C allows detailed representation of measured values, with resolution varying depending on the measurement range.

Compatibility and Accessories
The thermometer is compatible with various sensors, designed for different applications. These include flexible sensors such as SK20 (range -40 °C to +450 °C), SK2 (range -50 °C to +1000 °C), or SK15 (surface sensor, -50 °C to +900 °C). For special applications, needle-type (SK1, SK11), surface-type (SK4, SK5, SK14, SK19), and air temperature sensors (SK17) are also available. Extension cables such as CK1, CK2, CK3, and CK4 (each 1 m, operating range -40 °C to +100 °C) allow flexible adjustment of measurement length. A handle (PP1) is also available to improve handling during extended measurements.

Installation and Mounting
Installation is performed by simply connecting the desired sensors to the two inputs of the device. The sensors are attached directly to the measurement point, with the method of attachment (e.g. magnetic, spring-loaded, threaded) depending on the specific sensor type. The device itself requires no additional mounting; it is held in hand or supplemented with a handle (PP1). Batteries are included in the delivery and pre-installed, making the device ready for immediate use.

Operational Advantages
The thermometer offers high measurement accuracy, robust construction, and simple operation. The ability to measure temperature differences extends its functionality beyond single-point measuring devices. The IP65 protection rating ensures long service life even under harsh conditions. The combination of compact dimensions and low weight (200 g) enables mobile use. The availability of various sensors and extensions allows flexible adaptation to different measurement tasks.
