Helmholtz Coil HHROT-1

The SENIS Model HHROT-1 Helmholtz Coils is a single axis coil pair arranged in Helmholtz geometry to give a relatively large volume of high uniformity magnetic field. 
 
  • Magnetic field up to 20mT
  • High magnetic field uniformity: better than 4x10-4 over a 20mm sphere
  • Compact, with the weight of 32kg
  • Dimensions: 199 x 280 x 337 mm
  • Inner diameter 176mm
  • Possibility to rotate a magnetic sensor within the Helmholtz coils in all three angles (tilt, roll, pitch)

HEON Instrument for Hall and Magnetoresistance sensors chara

HEON instrument for Hall and Magnetoresistance sensors characterization – U/I-characteristics, Offset drift (fluctuations) and temperature coefficient, noise spectral density, sensitivity (utilizing a reference magnet), temperature coefficients (utilizing a thermal chamber).

HF Current Source

HF Current Source HEFR. High-frequency bipolar current source (DC–1MHz) SENIS HEFR for measuring the response of Hall elements to small-signal high-frequency magnetic fields.

Resonant Circuit Option

Resonant Circuit Option for Helmholtz Coils to generate higher currents, i.e. higher magnetic fields.
