**Precise magnetic field meter for DC and AC applications**
The PCE‑MFM 3800 is a precise magnetic field meter for detecting direct fields (DC) and alternating fields (AC) up to 3500 MT. With a consistent resolution of 0.01 MT, it enables reliable measurements from very weak to strong magnetic fields. In addition, the device detects ambient temperatures from 0 to 80 °C in order to better assess thermal influences.
**Accuracy depends on measuring range**
Depending on the field strength, the following accuracy specifications apply to the magnetic field meter:
0 ... 2400 mT: ±1% of reading
2400 ... 3500 mT: ±3% of reading
These range data facilitate the evaluation of the measurement results across the entire DC spectrum.
**Flexible AC/DC measurement with three operating modes**
The magnetic field meter offers three modes for detecting magnetic field types:
DC mode for direct fields, AC mode for alternating fields and automatic AC/DC detection for independent identification of the field type.
The automatic range selection ensures that the appropriate measuring range is always used.
**Unit conversion directly in the device**
The magnetic field meter supports several magnetic units, including MT, G, OE, WB/m², kA/m and A/cm.
The conversion between flux density (MT) and field strength (A/cm) is done automatically on the basis of the vacuum permeability:
1 A/cm corresponds in air to a flux density of 0.1257 MT. This allows measured values to be read directly in the desired unit without any additional effort.
**Modular sensor system for versatile applications**
The PCE‑MFM 3800 has a modular sensor system with push‑pull connector that enables rapid and safe sensor replacement. A transverse probe is included; an axial probe can also be connected. The modular concept allows the magnetic field meter to be flexibly adapted to different measurement tasks and installation situations.
**Colour display, data memory and USB‑C for easy evaluation**
The 2.8-inch color display provides a clear representation of real-time values, trend gradients, and maximum and average measurements.
**Other features:**
Data logger: 100 series of measurements, each with up to 21,000 points
USB‑C interface for fast data transfer
Free PC software for evaluation, live measurement and export (.pdf and .csv)
Thus the magnetic field meter is best suited for documentation, analysis and quality control.
**Suitable for industry, laboratory and development**
Thanks to its wide measuring range, high resolution and extended operating temperature range, the magnetic field meter is suitable for:
Residual magnetism testing
Analysis of permanent magnets
Testing of magnetic clamping devices
Material and component test
AC field measurements
Research and development tasks
