Designs and manufactures calibration and metrology instrumentation. Products include decade boxes, portable and benchtop calibrators, DMMs, and custom-made test benches..

Time Electronics – Precision Test Instruments

The 7080 CalBench consists of the workstation frame, table top, and primary console. The 7082 mains power module is fitted as standard in every bench. The remaining space in the primary console houses the modules selected by the user for their applications.

Calibration modules cover electronic signal, temperature, loop, and pressure applications. Power supplies, DMMs, oscilloscopes and generator modules can also be fitted into the bench consoles.

Each CalBench is built for the end user’s designated applications. With standard modules capable of calibrating multiple instruments and devices, and add-ons or modifications to cover user-specific requirements.

In 2000, IET Labs acquired the GenRad standards, impedance decades, megohmmeters, digibridges, audio and strobe lines and now continues to manufacture, service and support these “In the Genrad Tradition…”

IET Labs – GenRad Impedance Instruments

Products include the Standards and Decades products (Resistance, Capacitance, Inductance), Digibridges, Megohmmeters, Audio products, and Strobotac lines.

GenRad 1546 Digital Stroboscope

Since GenRad introduced the first commercial electronic stroboscope in the 1930’s, the GR models have remained the world standard.

GenRad 1546 Digital Stroboscope

The GenRad 1546 digital stroboscope emits a high-intensity, short-duration flash of light. The stroboscope features an electronic pulse generator that controls the flash rate, a line-operated power supply, and a light-emitting diode (LED) five digit readout in flashes per minute.

The instrument has internally and externally triggered modes of operation. In the Internal mode, the stroboscopes flash is triggered by an internal oscillator pulse which can also drive other IET stroboscopes for additional light sources. In the External mode, the 1546 operates as a digital tachometer.

History of Moog

“William C. Moog – inventor, entrepreneur and visionary. In 1951, Bill Moog developed the electro-hydraulic servovalve, a device that translates tiny, electrical impulses into precise and powerful movement. In July of 1951, Bill, his brother Arthur, and Lou Geyer, rented a corner of the abandoned Proner Airport in East Aurora and formed the Moog Valve Company.”
