Micro-ohmmeter
CHAUVIN ARNOUX

An easy-to-use, high-performance instrument, the C.A 6250 micro-ohmmeter tests the quality of links with precision (resolution of 0.1µΩ) through the use of low resistance measurements.
# 4-wire measurement method, 1µΩ to 2,500Ω (7 calibres, 3 with a 10A current)
# automatic compensation of spurious voltages at input terminals
# 3 measurement modes available depending on the application: inductive, non-inductive and automatic
# temperature compensation function for comparative results
# programmable alarms / 1,500-measurement memory capacity / direct printing of measurements on standard printer
# large backlit LCD display offering a wide range of symbols and indicators
# power supplied by rechargeable NiMH battery; battery life of 5,000 measurements at 10A
# IP 64: (casing closed) / IP 53 (casing open)
# dimensions: 270 x 250 x 180mm; weight: 4kg

OFFERS A WIDE RANGE OF MEASUREMENTS:
# Earth continuity tests
# Surface and metallization conditions
# Quality of contacts (switches, relays)
