Kanetec Tesla Gauss Meter - TM-801EXP

The Tesla Meter is a practical, handy type Gauss meter having digital display that has been developed based on KANETEC’s long experience and achievements in the manufacture of magnetism-applied products. To satisfy the user’s needs, this meter has been designed for easy use by anyone by incorporating frequently used functions only. Measurement of residual magnetism in machined workpieces.

  • Measurement of magnetic flux density in magnetism-applied products.
  • Measurement of magnetic flux density of motors.
  • Measurement of properties of magnetic materials.
  • A wide measuring range from 0 to 3000 mT. (DC)
  • In addition to DC magnetic flux density, AC magnetic flux density can be measured.
  • The high resolution measuring mode ensures highly accurate measurement. (Resolution 0.01 mT = 0.1 G)
  • The use of sheet keys ensures high dustproof performance.
  • The auto power off function prevents useless consumption of the battery.
  • When the probe has been worn out, it can be replaced with a new one without troublesome calibration. (Optional)Wider measuring range
  • High resolution mode accuracy in measurement of DC magnetic flux density improved. Frequency covering range in measurement of AC magnetic flux density expanded. (40 ‒ 500 Hz)
  • Max. 160 hours of continuous operation and high-speed sampling Sampling speed in HOLD mode increased by 1.5 times. Continuous operation time by use of a battery improved by 20% (130 hours → 160 hours). 3-way power supply usable: battery, AC adapter and USB feed.
  • PC operation simpler and more useful
  • Digital output of measured data to PC by use of USB.
  • Measurement commands controllable from PC by use of USB. 
  • PC free sample software renewed completely.
