The Gaussmeter CYGM99A is a portable, microprocessor-controlled device engineered to deliver high-resolution DC and AC magnetic field strength measurements using the Hall Effect principle. Manufactured by Chen Yang Technologies, this instrument provides an accessible solution for quick quality checks and comparative measurements on permanent magnets, motors, and magnetic transducers.
Key Features & Functions
High-Precision Measurement: Measures both static (DC) and dynamic (AC) magnetic fields. It features a basic accuracy of ±1.0% for DC ranges and ±2.0% for AC ranges.
Versatile Readout: Equipped with a 5-digit LCD screen capable of displaying units in either mT or Gs (1 mT = 10 Gs).
Advanced Display Controls: Includes display functionalities for RMS/Peak values during AC measurement, N/S pole indication for DC measurement, and Max hold, Min hold, and Display hold functions.
PC Integration: Supports remote control and direct data communication with a computer via the included USB cable for further processing.
Flexible Power Options: Operates via three 1.5V AA batteries for field use or a 5V DC USB adapter for stationary applications.
