Chauvin Arnoux P01103081 Kelvin-Pistolenprüfspitze retractable 25 A with 3 m cable (2 pcs) content_copy

The product from Chauvin Arnoux is a set of two retractable Kelvin test probes in pistol format, designed for measurements with a current load capacity up to 25 amperes. The probes are equipped with a 3.15 metre long cable and are intended for safe and precise contact during electrical measurements, particularly in electrical engineering and industrial environments. The retractable design allows for compact storage and safe transportation, while the pistol format ensures ergonomic handling.

Kelvin test probes are specifically designed for measuring voltages and resistances, where the four-wire technique enables separation between current and voltage paths, minimizing measurement errors caused by contact resistance. This technique is particularly used for resistance measurements requiring high accuracy, such as testing conductors, switches, or fuses. The probes are suitable for use in electrical installation, machine building, and maintenance technology.

Retractable probes offer the advantage of being retracted into the handle housing when not in use. This protects the probes from damage and reduces the risk of accidents due to unintended contact. The pistol format ensures secure and comfortable handling, especially during extended measurement procedures, and allows for precise targeting of the measurement point.

Cable with 3.15 m length provides sufficient freedom of movement during work, without requiring the measuring instruments to be positioned directly at the measurement site. The cable length is suitable for typical applications in workshops, construction sites, or industrial facilities. The cables are designed for use with measuring instruments equipped with corresponding connection sockets.

The four-wire technique (Kelvin test technique) is crucial for accuracy in resistance measurements. In this method, current is supplied via a separate conductor, while voltage is measured on a second, galvanically isolated conductor. This eliminates the influence of contact resistance at the measurement point, which is particularly important for small resistances.

The probes are designed for a current load up to 25 A, making them suitable for use in many industrial and craft applications. The maximum current rating is sufficient for most testing and maintenance tasks, especially when combined with appropriate measuring instruments.

The pistol format provides ergonomic handling and enables precise targeting. The design is particularly suitable for users who frequently work with measuring instruments and require secure, comfortable handling of the probes. The retractable construction also ensures compact storage.

The use in electrical engineering includes testing of conductors, switches, fuses, and other electrical components. The probes are especially suited for resistance measurements requiring high accuracy. They are often used in combination with multimeters or specialized resistance measuring instruments.

Compatibility with measuring instruments is ensured, provided the instruments have corresponding sockets for Kelvin test probes. The probes are not designed for a specific device, but are intended as universal measuring accessory components. Their use does not require additional adapters or tools.

Mounting and installation are performed by simply connecting the probes to the measuring instruments. No additional mounting or fastening steps are required. The probes are ready for immediate use after unpacking.

Operational safety is supported by the retractable design and robust cable construction. The probes are designed for use in professional environments where reliable and safe measurement is required. The cables are designed to withstand mechanical stress and wear.

Operational advantages include high measurement accuracy through the Kelvin technique, ergonomic handling, and compact storage. The probes reduce the risk of measurement errors and enable efficient work during resistance measurements. The retractable construction also contributes to a longer service life by protecting the probes from mechanical damage.
