Gaussmeters and Fluxmeters   

Lake Shore Magnetic Instrumentation   

  • Teslameters
  • Fluxmeter & Gaussmeters
  • Hall Probes & Controllers

Lake Shore Cryotronics offer a range of instruments for the scientific researcher or industrial quality controller working in the field of magnetics. These include: Gaussmeter and Teslameter instruments for measuring DC and AC magnetic fields, and controlling DC fields; Fluxmeters for measuring total flux, which are ideal for magnet testing and sorting, and as the main component in BH loop or hysteresisgraph measurement applications; and axial, transverse, multi-axis, gamma, and tangential Hall probes for measuring magnetic flux density.


TruZero™ technology
A typical Hall probe must be regularly placed in a zero gauss chamber in order to zero out offsets that develop over time and affect measurement accuracy.

Lake Shore’s TruZero™ technology eliminates the need to perform these frequent zeroing operations via an onboard algorithm combines the sequential Hall voltage readings in a way that eliminates any offsets due to misalignment and thermoelectric effects.

This method also reduces flicker noise, meaning that readings are both more accurate and more precise.


Connectivity choices

  • Wi-Fi
  • Ethernet
  • USB
  • GPIB via an optional module

F41 & F71 Teslameters

The new F41 Single-axis and F71 Multi-axis teslameters from Lake Shore Cryotronics offer a new level of precision and convenience for engineers, QC technicians, and lab researchers. In conjunction with a new series of compatible Hall probes and 2Dex™ Hall sensors, users can measure with confidence in challenging applications.

The F41 and F71 teslameters work equally well on a benchtop or in a rack. The TiltView™ display makes them easy to operate even when mounted in the bottom of a rack.

Probe swapping is now much faster due to a compact quick-release connector and integrated calibration data for all probes.

Features

  • TruZero™ technology minimises misalignment voltages and eliminates the need to re-zero a probe
  • Latest Hall sensors offer excellent sensitivity and are highly linear over a very wide field range
  • Uncluttered tiltable touchscreen interface that's instantly familiar to smartphone owners

FP Series probes
Lake Shore offers FP Series probes for every requirement, including 3-axis (vector), transverse, and axial models available in both handheld and mountable versions.

The smaller, ultra-thin active area on the new sensors ensure more accurate field readings and all but eliminates planar Hall effect errors that have caused measurement offsets in current-generation 3-axis probes.

The durable handheld probes are lightweight and comfortable to use, with an ergonomic handle design for more precise positioning. They provide the convenience of spot measurement, delivering a quick way to confirm field values where fixing is impractical or not required.

Mountable probes feature a flat machined aluminium surface with location holes for precise alignment. They are easily held in place with just two screws. Drawings and CAD models are available for OEM integrators. Custom designs can be engineered if the application requires it: please contact us for details.

The FP Series probes incorporate proprietary 2Dex™ Hall effect sensors that enable TruZero™ technology and also aid in measurement dependability. These next-generation magnetic field sensors for demanding scientific and industrial applications are highly linear over a very wide field range, inherently rugged, and operate over a wide range of temperatures.


M91 FastHall™ Controller

M91 controller Lake Shore's new MeasureReady M91 FastHall™ controller is an advanced all-in-one instrument that delivers significantly higher levels of precision, speed, and convenience to researchers involved in the study of electronic materials.

The unique FastHall measurement technique fundamentally changes the way the Hall effect is generated and measured by eliminating the need to switch the polarity of the applied magnetic field during the measurement.
