34420A Agilent Micro Ohmmeter


The 34420A is a Micro Ohmmeter from Agilent. Micro ohmmeters take low-resistance measurements of a device’s electrical resistance, or resistance to an electric current. Micro ohmmeters collect information in ohms, the measure of electrical resistance. With a micro ohmmeter, engineers can document, analyze, and log the contact resistance of devices, such as rail/pipeline bonds, aircraft frame bonds, circuit breakers, and switch breakers. Current List Price $4543.
