Three-Channel Precision Laboratory Teslameter Brockhaus GM-460

Code: Brockhaus GM-460
 
BROCKHAUS
 

» Technical Specs

  • Three-channel Gaussmeter for determining the magnetic field strength of permanent magnets and systems
  • Measurement of magnetizing pulses
  • User-friendly measuring instrument
  • Mains supply
  • Application in laboratories and in production lines
  • Field and temperature measurement via the probe input
  • Automatic temperature compensation
  • Application as a single-, two- or three-channel Gaussmeter

 

Operating principle

Multi-channel Gaussmeter with a resolution of 5 3/4 digits. Up to a maximum of three probes can be connected simultaneously. Each measuring channel is shown in one line in the display. Measurement of Hall voltage created in the Hall sensor which is proportional to the adjacent magnetic field.

All the functions are displayed and controlled via the front panel of the instrument. Input via keyboard, readings on a 4-line fluorescent display with alphanumerical text. Measuring range, zero, and functions such as max hold, relative or alarm, can be set individually for each channel.

Two analogue outputs provide high accuracy and the possibility to analyse the development of the field. The corrected analogue output shows the exact value displayed, the non-corrected analogue output shows the field strength in real time.

The comprehensive Hall probe programme includes over 500 different measuring probes, as well as conventional transverse and axial probes and probes for bi-and tri-axial measurements. BROCKHAUS also supplies probes for low temperature applications and for measuring minimal magnetic fields.
