YW-821 is a handheld portable multi-functional magnetic field measuring instrument, which uses Hall probe to measure magnetic induction

intensity. It can be used for working magnetic field measurement of speakers, magnetic separators, iron separators and DC motors, surface

magnetic measurement of permanent magnet materials, residual magnetic measurement of mechanical parts, etc.

This series has three models: YW-821, YW-821-H and YW-821-A. The accuracy is grade 1, grade 2 and grade 5 respectively. They are suitable for different measurement scenarios, and users can choose according to their needs.

 

YW-821 has a peak measurement function, which can capture the peak when the pulse changes rapidly. During the measurement process, to capture the maximum magnetic field, the user only needs to switch the peak measurement mode to obtain the current maximum magnetic field value in real time.

 

YW-821 can set high and low alarm thresholds. After setting, as long as the measured value reaches or exceeds the preset alarm threshold, the instrument will give an alarm prompt. The instrument has a screen backlight that allows users to easily read measurements even in poor lighting conditions.
