KD2683B volume/surface resistivity tester is a multi-purpose comprehensive measuring device for measuring the volume resistivity and surface resistivity of solid and liquid insulating materials using the principle of annular three-electrode method. The resistance test range is 10KΩ ~ 10TΩ. Resistivity test range 10kω.cm ~ 10tω.cm; Micro current test range 10pA~1mA.

High brightness, super clear 4.3 inch color LCD display: display pixels: 480*272, a variety of parameters display at the same time.
Multiple trigger modes: internal trigger, external trigger, foot switch trigger, interface trigger.
Correction function: full range open circuit clear zero function.
Comparator (sorting) function: 4 files of sorting data are built in, which can PASS/FAIL judgment on the tested parts.

Handler interface: Output the sorting result and EOM end signal, and input the trigger signal.
RS232 interface: Use three-wire simple serial interface to communicate and connect with the host computer.
RS485 interface: RS485 interface for communication and connection with the host computer.
USB HOST: Uses a USB communication cable to communicate with and connect to the host computer.
USB DEVICE: Use a USB flash drive to access the device and save test data. Firmware can also be upgraded remotely.
