The 1920 1 MHz LCR Meter is designed to perform capacitance and impedance measurements on a variety of electronic components and materials over a frequency range from 20Hz to 1MHz. Both the QuadTech 1910 and 1920 LCR Meters, are now manufactured by IET Labs. Emphasis has been placed on ease of use through menu programming, and fast accurate production testing via its remote control capability from standard GPIB, RS-232 and handler interfaces.

15 Different Impedance Parameters/20 Total Parameters Measure and display any two parameters simultaneously, to achieve coverage
and flexibility not previously available.
Automatic Test Sequencing Run up to six different tests in sequence with a single push of the start button. Each test can have different conditions and limits.
Program and Data Storage Test setups can be stored and recalled from internal memory. The front panel can be locked out, with password protection, to ensure procedures are run the same way every time.
Load Correction Substantially improves instrument accuracy by performing measurements on a known standard and applying correction to subsequent measurements. Ideal for repetitive testing of identical devices at like test conditions.


Why Buy The 1920 Precision 1MHz LCR Meter?

  • For a wide frequency range (to 1MHz) at an affordable price
  • When both AC impedance and DC resistance measurements are needed
  • For automated production testing using RS232, IEEE-488 & PLC interfaces
  • When internal bias current is required for testing coils and inductors
  • Configure instrument and log results to PC using the 1900 Virtual Front Panel
