Description

L’IET LOM-510 avec son écran et son menu de face avant est idéal pour la mesure simple et précise de très faibles résistances. Sa précision de 0,05% et sa gamme de mesure de 1µΩ à 2 00Ω en font un des instruments les plus polyvalent et efficient du marché La mesure se fait en 4 points supprimant ainsi les résistances de cablage et le mode DC permet de supprimer les bruits EMF Adapté pour les tests en production – le LOM-510 a une sortie numérique. Un nombre importants d’accessoires peuvent accompagner votre LOM-510 (pinces kelvins, micro-éléctrodes, kit de calibration…)

Un milliOhmmètre pour des mesures de basses résistances précises

Key features

Excellent rapport qualité/prix
Mesure 4 points pour plus de précision
