MP-810 — Compact Magnetic Field Meter / Gaussmeter ("Swift Class")

Overview

The MP-810 is a compact, single-handed magnetic field meter designed for fast and precise measurement of DC and AC magnetic fields as well as pulse-field peak values. It is available in two probe configurations: the MP-810A with an integrated axial field probe (measuring along the probe axis at a defined 2.0 mm distance), and the MP-810T with a transverse field probe (1.7 mm thickness, 0.9 mm Hall sensor distance) — ideal for measuring in air gaps, cavities, and for crack detection on workpiece surfaces.

The MP-810 features an illuminated OLED graphic display, a built-in data logger with capacity for 4,000 measurements, and statistical evaluation (count, max, min, average, standard deviation). A wireless interface enables communication with Android, iOS, and Windows devices via the free Lima Connect app for project management, measurement-point photo assignment, and graphical data analysis. Weighing just 73 g with the battery installed, it is one of the lightest full-featured gaussmeters available.

Units are switchable between A/cm, kA/m, Gauss, Oersted, and Tesla. An optional calibration standard (reference magnet) and Zero Gauss Chamber are available for probe verification and calibration independent of the Earth's magnetic field.

MP-4000 — Professional Magnetic Field Meter with Scan & Trigger Measurement

Overview

The MP-4000 represents List-Magnetik's most advanced magnetic field measurement platform — a professional-grade instrument with unique digitizing technology. Its external digital probes (axial PM4-A; transverse PM4-T, PM4-TR, and PM4-TF) contain the measurement electronics directly within the probe body, digitizing and linearizing the Hall sensor signals at the source for exceptional interference immunity — critical when measuring at the lowest field strengths.

A standout feature is the 200 kHz digitization rate, enabling the MP-4000 to capture and display magnetic pulse waveforms as short as 0.1 milliseconds with precise peak-value and pulse-duration readouts. AC field waveforms up to 20 kHz can be recorded and stored. The scan measurement function continuously records magnetic fields across an area with statistical evaluation, while the trigger measurement mode captures transient pulses with exact timing — capabilities unmatched by conventional gaussmeters.

The instrument features a 320 × 480 pixel color LCD touch panel (75 × 50 mm), a data logger for 10,000 measurements, and wireless connectivity to the Lima Connect app on Android, iOS, and Windows. A USB SCPI communication interface supports remote-controlled measurements and integration into automated test systems. The device can be powered externally via USB for continuous operation — ideal for production-line and laboratory automation.

MP-1000 — Versatile Handheld Magnetic Field Meter

Overview

The MP-1000 is a flexible handheld magnetic field meter with externally connectable, plug-in probes — covering axial, transverse, flexible reed, and angled axial configurations. This modular design allows one display unit to serve multiple measurement geometries, making it a cost-effective solution for labs and workshops that encounter varied measurement challenges.

The MP-1000 measures DC fields, AC fields (true RMS), and pulse peaks with a minimum pulse duration of just 0.1 milliseconds. Like the MP-4000, each probe contains a microcontroller that digitizes and linearizes the Hall sensor signals within the probe itself, delivering clean, interference-immune readings even at very low field strengths just above the Earth's magnetic field. This makes it especially well-suited for residual magnetism measurement and stray-field detection for crack testing.

The plug-in cable design means a damaged probe cable can be replaced in the field without returning the entire instrument. A clear 3-digit LCD display, simple push-button operation, and IP64-rated housing ensure reliable performance in industrial environments.

MP-80 V2 — Residual Magnetic Field Meter

Overview

The MP-80 V2 is a purpose-built, single-handed instrument optimized for measuring residual magnetism (remanence) on ferromagnetic iron and steel parts. It is the go-to tool for verifying that demagnetized parts meet cleanliness specifications before or after machining, grinding, or welding operations — a critical quality-assurance step in precision manufacturing, bearing production, and aerospace component inspection.

The MP-80 features an integrated axial field probe with a precise 2.0 mm measuring distance from the probe tip, optimized for the low-field range of 0–100 A/cm (0.01–12.5 mT). It delivers an accuracy of ±0.3 A/cm below 10 A/cm — well-suited for detecting even trace remanence. The device auto-zeros at power-on (probe must be outside any magnetic field) so the operator is ready to measure within seconds.

An illuminated OLED graphic display with an analog bar graph provides clear visual feedback, while the Peak Hold function (approximately 10 readings per second) captures transient residual field values. Measuring units are switchable between A/cm, kA/m, Gauss/Oersted, and Tesla. The MP-80 also includes a wireless interface for data transfer to Android, iOS, and Windows via the Lima Connect app.
