1750C Micro-Ohmmeters

Recognized as the industry’s fastest precision micro-ohmmeter, the 1750 Series micro-ohmmeters by TEGAM have become the #1 choice in manufacturing environments.  Fuse manufacturers use it for nondestructive tests where the unmatched precision increases the process yield to the point where the 1750 pays for itself in weeks. The vast majority of resistors less than 1 Ohm are tested and sorted to accuracy better than 0.1% by the 1750.  Automotive suppliers use it to consistently meet stringent quality requirements of welds, bonds and electrical connection in sub-assemblies. Aircraft manufacturers employ the 1750 micro-ohmmeter to measure wiring harnesses and RF shields for connection integrity.  The capability of the 1750 enables the accurate real-time measurement of electro-plating thickness and conductive coatings on housings and shields.

TEGAM’s 1750 Series micro-ohmmeter employs multiple techniques to achieve its impressive accuracy.  A four-wire kelvin technique eliminates the effects of lead resistance while offset compensation removes the errors caused by thermal contact voltages.  The 1750 even monitors its performance over time and adjusts its calibration against a set of internal low temperature coefficient resistors to ensure consistent measurement performance without constant recalibration.

TEGAM specializes in low resistance measurement.  Our technical sales staff and applications engineers understand both the measurement challenges you face and your manufacturing environment.  They can help you solve your product-yield or quality problems with low resistance measurements.
