Hioki 8972 DC/RMS Unit
Introducing the DC/RMS UNIT 8972, a versatile and high-resolution waveform measurement device designed for precision and accuracy in a wide range of applications. This advanced unit is equipped with a range of features that make it a must-have tool for engineers, technicians, and researchers.
The DC/RMS UNIT 8972 is designed to measure both instantaneous and RMS waveforms with high 12-bit A/D resolution, providing you with accurate and reliable readings every time. With its isolated 2-channel input, you can measure signals from two different sources simultaneously, saving you time and effort.
The DC/RMS UNIT 8972 is also built to withstand high voltages, with a maximum rated voltage to ground of 300 V AC, DC (CAT II). This makes it suitable for use in a range of industrial and laboratory settings, where high voltages are often present.
One of the standout features of the DC/RMS UNIT 8972 is its wide bandwidth RMS rectifier, which can measure signals from low to high frequency, from DC to 30 Hz to 100 kHz. This allows you to measure both AC and DC signals accurately, making it ideal for a range of applications.
Finally, with the DC/RMS UNIT 8972, you can monitor instantaneous waveforms without the need to pass through the rectifying circuit, providing you with even more flexibility and accuracy when measuring signals.
Overall, the DC/RMS UNIT 8972 is an essential tool for anyone working with waveform measurements. Its high resolution, isolated input, and wide bandwidth RMS rectifier make it an indispensable addition to any laboratory or industrial setting.
