MTE Laboratory Impedance Standards

Product catalog summary

Highlights
- Resistance and Capacitance standards are available in four package types for various applications.
- Custom nominal values and terminal configurations can be requested.
- Designed for calibration of ohmmeters, LCR meters, and insulation testers.
- Can be used as transfer standards for maintaining traceability between laboratories.

Description
The MTE series offers resistance and capacitance standards suitable for calibration purposes. They are available in four terminal configurations to accommodate different applications, including OPEN and SHORT standards for zero calibration of LCR meters. Custom configurations are available upon request.

Package Types
