Linear Resistance Measurement ResTest 50

New

Product ID: 3758

ResTest 50 perfectly masters the problems experienced in the measurement of small sections, especially with flexible, and/or insulated conductors.

Description:

Compacting Jaws:
- Drastically reduce contact resistances between wires.
- Ensure a good distribution of the current.
- Key factor for precise and reproducible measurements.
Self-Cutting Knives:
- Equipped with an LED-based contact monitoring system.
- Enable safe and efficient use with insulated cables.
Measurement System:
- Includes a ruler with calibrated length.
- Temperature sensor for accurate linear resistance value, directly in Ω/km @ 20ºC.
Integrated Equipment:
- Offers operating comfort.
- Mastery of all measurement uncertainties.
AESA Specification:
- Specifies overall measurement accuracy, not just the micro-ohmmeter.

Key Features:
