Calmet – Calibration Test Equipment

Name Calmet derive from words CALibrators and METrology – the main action’s field of Calmet company.

The C101F Calibrator enables generating direct (DC) and alternating (AC) voltages up to 1100V in five subranges 0.1-1-10-100- 1000V, DC and AC currents up to 20.5A in five subranges 0.001-0.01-0.1-1-10A (the C101FC option up to 100A AC).

Multifunction Calibrator of alternating and direct voltage and current

C101F Calibrator - Calmet

The C101F Calibrator is characterised by high accuracy, high output power, small dimensions and light weight.

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.

Established in 1980 and located in TangChen Industrial Park, Sanchung city, Taipei. They have systems and solutions in the field of IC test and programming equipments. Component Testing equipment too.

Leap Electronic – IC Test and Custom Equipment

The Products the make include IC programmers and Testers. Learning Kits and Emulators. They also have Logic Analyzers and Power Supplies. Automated Programming Systems too.

Impulse Winding Tester - Leap Electronic

IWT-5000A winding tester is a coil (such as voltage transformer, inductance, motor) testing instrument that tests self-insulating property of the coil. The influences of winding materials, magnetic materials, and framework, also extra fabrication decreases the insulating property of coil layers along with the jumpers and jacks.

hp or  Hewlett-Packard  started as a T&M Firm.  Agilent  Technologies continued the Instrumentation Products after hp became a computer company.  Now Keysight Technologies is the new name for the Instrumentation Division. Agilent now is a Life Sciences company..

Keysight Technologies - Test and Measurement

“From a small garage in Palo Alto, California, to employees around the world serving customers in 110 countries, Agilent has a long history of innovation and leadership in the communications, electronics, semiconductor, test and measurement, life sciences and chemical analysis industries.”

Keysight Technologies – Test and Measurement

The company founded by William “Bill” Redington Hewlett and Dave Packard was know as Hewlett-Packard Company or HP. This was a Test and Measurement company. First popular product was a precision audio oscillator, the Model HP200A.

Later Computer and Printer products divisions retained the brand and firm and Agilent was spun off for for the Test and Measurement and other non-computer product line.
