Take the Guesswork Out of Magnetic Measurement

The GOYOJO AMST Digital Gaussmeter is a professional-grade handheld instrument designed for engineers, researchers, and quality control specialists. From inspecting the surface magnetism of permanent magnets to measuring the DC magnetic field levels in complex industrial machinery, this tool provides the laboratory-level precision you can carry in your pocket.

Why Choose the GOYOJO AMST?

Unlike standard meters, the AMST utilizes Multi-Level Accuracy (Class 1, 2, and 5) and automatic range switching. When your readings exceed 200mT, the device intelligently adjusts its range up to 2000mT+ to maintain data integrity. The backlit 4-digit display ensures you can read critical data in dim factory environments or bright outdoor settings.

Whether you are identifying N/S Polarity or ensuring a magnetic separator is running at peak efficiency, the GOYOJO AMST delivers the reliability required for high-stakes industrial applications.

• 【Ultra-Wide Measurement Range】 Accurately measure magnetic fields from 0 to 2400mT (24,000 Gs). Whether you are testing residual magnetism or industrial-grade permanent magnets, this device provides the range you need for diverse applications.

• 【Precision Hall Sensor Technology】 Equipped with an advanced high-sensitivity Hall sensor and digital signal processing. Features A/D conversion and digital filtering to deliver ±1% high-accuracy readings that outperform traditional analog meters.

• 【Dual Units & Intelligent Functions】 Effortlessly switch between mT (millitesla) and Gs (gauss) with a single click ($1mT = 10Gs$). Includes a Maximum Value Hold function and one-key zero adjustment for seamless data collection.

• 【Smart Power Management】 Powered by a 9V battery with an integrated 5-minute auto-shutdown feature. This ensures your device is always ready when you need it and prevents battery drain from accidental "on" states.

• 【Industrial & Educational Versatility】 The go-to tool for measuring surface magnetic fields in DC motors, magnetic separators, medical equipment, audio speakers, and classroom physics experiments.
