High-accuracy measurement of DC, AC, and pulse magnetic field strength Sensors used in Tesla meters (Gauss meters) are: - Measurement of the amount of magnetization of horizontal type GV-400T magnets using Hall elements and residual magnetism of steel materials - Search coil measurement There is a vertical type that can be used, and a search coil is used to measure the pulse magnetic field during magnetization of the GV-400A.
- This is a handy Tesla meter weighing approximately 110g.
- Equipped with a backlit color LCD, it maintains high visibility even outdoors.
- It can measure a wide range from 0.01mT to 1.999T and is equipped with a peak hold function.
- Ideal for measuring alternating magnetic fields. Compatible with DC ~ 300Hz.
- In addition to charging from AC power (approximately 135 minutes), it is also possible to use
- DC power with AAA rechargeable batteries (6 hours of continuous operation).
