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.

Voltage dividers and voltage references provide highly-accurate reference voltages for calibration and testing purposes

Thermocouple simulators and resistance temperature detector (RTD) simulators provide precise standard values of resistance or voltage for simulation and calibration.

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

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

Inertial and gyro systems use a combination of accelerometers and angular rate sensors (gyroscopes) to detect altitude, location, and motion.

Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters.
