ATS-300M — Stalloy Iron Loss Tester

General Information:

ATS-300M Iron core Magnetic Parameters Tester is made to measure dynamic hysteresis loop, magnetizing curve and power loss curve of stator core of Motor (stalley), iron core of industrial frequency transformer, finished transformer, amorphous, ultracrystallite and permalloy iron core (closed loop sample) under the condition of frequency 50Hz or 60Hz .

Accurate measurement of magnetic core amplitude permeability μa, loss angle δ, specific total loss Ps, trace Br, coercive force Hc and other dynamic magnetic characteristic parameters.



    • Output low-distortion sine wave with or without load.
    • Auto range for both excitation power voltage and current according to the test samples and number of turns.
    • 32-bit embedded high speed processor with powerful function of data processing.

Test hot rolling, cold rolling and non-oriented stalloy iron core, permalloy, amorphous and other soft magnet cores.

  • Test sample shapes: toroid, E-shape, U-shape and other closed samples.
  • Support sorting, simple operation, suitable for field measurement.
  • 320×240 large LCD screen to display waves, curves and test results.
  • Supports USB 2.0 HOST interface (with compatible USB disk).
  • Supports RS232 interface, Optional ATSView software (Sold separately).



Measuring Accuracy (Warm-up for half an hour; Temperature: 18°C ~28°C Humidity: 30~ 75% Test under circumstance of no external magnetic field.):
