Resistance standards and decade boxes provide a highly accurate standard value of resistance for calibration and testing.

Calibration standards and reference sources include any source that can provide a reference for the calibration of an instrument or comparison of a material or component.

Capacitance standards and decades provide a highly accurate standard value of capacitance for calibration and testing.

Inductance standards and decades provide highly accurate and digitally variable standard values of inductance for calibration, comparison and testing.

Temperature instruments use contact or noncontact methods to measure temperature.

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.

Decade boxes and dividers provide highly accurate and digitally variable standard values of resistance, capacitance, inductance, voltage and/or current for calibration, comparison and testing.
