About This Product

This is a device for measuring the contact resistance of the main contact part of power circuit breakers, etc.

■Summary

Based on the low resistance measuring device CVE-18, which has been used by customers for many years, we have improved it so that it can be used for measuring and inspecting the volume resistivity and temperature coefficient of materials and samples. Features

■Wide resistance measurement range

The measurement range covers a wide range of 0.0001mΩ to 2000mΩ.

■Eliminates the effects of thermal electromotive force

By measuring the polarity of the current in two directions, one in the forward direction and the other in the opposite direction, and taking the average, it is possible to eliminate the influence of thermoelectromotive force generated between the specimen and the electrode. This allows for accurate resistance measurements.

■Temperature measurement function

By connecting a temperature sensor, you can measure resistance and temperature at the same time.

■Repeat function and data storage function

Resistance and temperature measurements can be repeated at 1 minute intervals. All repeated measurement data can be saved as a file by connecting to a computer. Connect to your computer via RS232C or USB (optional USB-RS232C conversion adapter required).

■Touch panel operation and display

All operations are performed using the touch panel on the display, making operations easy to understand.
