Micro-ohmmètres – Chauvin Arnoux , CA6240, CA6255, CA6292

These micro-ohmmeters by Chauvin Arnoux, specifically CA6240 and CA6255, are designed for precise measurement of very low resistances (ohmic and micro-ohmic) for checking contacts, cable joints, and conductive sections.

• The description claims the CA6240 is robust and suitable for measuring very low resistances with a 4-wire method to reduce cable errors.
• The description claims a resistance range of 400 µΩ to 400 Ω with a resolution up to 1 µΩ.
• The description claims the CA6240 can handle a current test up to 10 A.
• The description claims the device has an IP53 robust housing and IEC 61010-1 CAT III 50 V safety rating.
