Product Description:
The CT237 current probe has been designed for use with digital multimeters, recorders and other suitable equipment for accurate non-intrusive measurement of AC, DC and complex waveform currents.
Using advanced Hall Effect technology the CT237 can accurately measure currents up to 200 A r.m.s. over the frequency range of DC to 10KHz. These features make it a powerful tool for use in inverters, switch mode power supplies, industrial controllers, automotive diagnostics and other applications requiring accurate isolated current measurements.
