Accessories

A variety of five coils can be connected:

  1. Transversal probe HS-T 301, dimensions 70 mm x 5 mm x 1,3 mm (measured without handle) For measuring magnetic fields running at right angles with the probe’s centre line
  2. Axial probe HS-A 301, dimensions 70 mm x 6 mm Ø (measured without handle)For measuring magnetic fields running towards the probe’s centre line
  3. Transversal probe HS-T601, dimensions 70 mm x 5 mm x 0,8 mm (measured without handle) For measuring magnetic fields running at right angles with the probe’s centre line
  4. Axial probe HS-A Geo, dimensions 200 mm x 12 mm Ø (measured without handle) For measuring small magnetic fields (also geological) running towards the probe’s centre line. This probe is 10 times more sensitive as the other probes. Thereby it will be generated an additional measuring range 2,000 mT.
  5. Radial probe HS-R 301, dimensions 70 mm x 5,8 mm x 4,0 mm (measured without handle) For measuring radial magnetic fields in a well > 6 mm

Special sensor dimensions and the installation of sensors in other devices to customers’ specifications are possible. Setting of the Field Strength Meter H1-4 zero point and calibration of the instrument are performed by the trimmer on the front panel. Field Strength Meter calibration is effected using an internal calibration voltage. Even greater measuring accuracy is achieved by using reference magnets that are available in different field strengths. These are unaffected by external fields and highly stable against artificial ageing. The H1-4 Field Strength Meter has an analogue output port for connection of an A/D converter for digital further processing of the output voltage.
