The GCP-020 current clamp
The GCP-020 is a clamp-type probe for measuring AC and DC waveforms. With a measurement range of 100 mA to 200 A, the GCP-020 is designed to measure high currents in a compact package. To measure current waveforms, simply clamp the clamp around the conductor to be tested and connect the cable to the BNC input of an oscilloscope. It is no longer necessary to break the circuit and connect an ammeter in series. By combining a Hall-effect sensor and an AC current transformer, the GCP-020 provides accurate measurement from 40Hz to 10kHz. The dual measuring range covers 100mA~20A and 500mA~200A. In addition to oscilloscopes, the GCP-020 can also be connected to multimeters and data loggers.
Founded in 1975, Good Will Instrument Co., Ltd was the first professional manufacturer in Taiwan specializing in electrical test & measurement instruments. GW Instek began as a manufacturer of power supplies and quickly expanded into the development of high precision electronic test and measurement instruments.
After decades of experience in the test and measurement industry, GW Instek has grown to become one of the important manufacturers and developers of test and measurement instruments worldwide. Today GW Instek has more than 300 product items, ranging from oscilloscopes, spectrum analyzers, signal sources, basic test & measurement instruments to video surveillance systems. GW Instek has also seen its present growth internationally. With headquarters located in Taipei, Taiwan, GW Instek has subsidiaries in mainland China, America, Japan, Korea, Malaysia, Europe, and India; its products are sold to more than 80 countries worldwide.
With a strong focus on high quality, economical measurement solutions for the educational and industrial manufacturing markets, Good Will Instrument has developed a solid brand image and reputation for reliability, integrity and innovation.
