MEASTEK HCTM0120A High Current Precision Measurement High Frequency
Flexible Current Probe High Sensitivity Current Probe
Ultra-high sensitivity and precise detection
With a high sensitivity of 50mV/A, it can accurately capture tiny
current changes. Even extremely weak current fluctuations cannot
escape its "eyes", providing you with high-precision measurement
data to meet application scenarios with strict requirements on
current accuracy.
Excellent stable noise resistance
The maximum noise is only 12mV Vpp, and it can work stably in a
noisy electromagnetic environment, effectively reducing the impact
of external interference on the measurement results, ensuring the
reliability of each measurement data, so that you don't have to
worry about measurement errors.
The wideband current probe covers a variety of scenarios
The low-frequency bandwidth -3dB is 10Hz, and the high-frequency
bandwidth -3dB is 15MHz. The wide frequency coverage range makes it
suitable for the measurement of various common current frequencies,
whether it is low-frequency industrial equipment current or
high-frequency electronic circuit current, it can easily cope with
it.
Safety and insulation guarantee
The insulation voltage value is as high as 2KV, providing reliable
safety protection for your measurement operations in high-voltage
environments, avoiding the risk of electric shock, ensuring your
personal and equipment safety, and making you feel more at ease
when using it.
Small, light and easy to operate
The overall design is small and light, easy to carry to different
work sites. Whether it is precision testing in the laboratory or
equipment maintenance outdoors, it can be easily operated, greatly
improving work efficiency.
Application scenarios
Suitable for electronic equipment R&D laboratories to test
small currents on new circuit boards; small motor production
workshops to detect currents during motor startup and operation;
communication base station equipment maintenance to measure tiny
current fluctuations in internal circuits.
