DTM-351 Digital Teslameter – High-Performance, 3-Axis Magnetic Field Measurement with USB Connectivity

​

The DTM-351 Digital Teslameter is the latest advancement in Group3’s trusted line of precision magnetic field measurement instruments. Designed for demanding applications, it delivers high-resolution, 3-axis magnetic field measurement using temperature-compensated Hall-effect probes, with full USB serial communication and data logging support for streamlined integration into modern laboratory and industrial environments.

 

Engineered with the same proven technology and precision as the DTM-151, the DTM-351 expands capability with a full 3-axis configuration—essentially combining the functionality of three DTM-151 units into one compact system. This allows for simultaneous X, Y, and Z axis measurement with a single USB output for simplified operation and faster setup.

 

The DTM-351 is fully backward-compatible with existing Group3 Hall-effect probes, but we recommend pairing it with the 3DT-141 (standard sensitivity) or 3DT-231 (high sensitivity) probes to unlock its full potential.

​

Key features include:

  • 3-axis measurement with high accuracy and temperature compensation

  • USB interface for fast, reliable data communication and logging

  • Comes with LabVIEW-based custom VI software running on Windows 10/11

  • Support for vector summation, custom commands, and automation

  • Seamless transition for current Group3 users—no need to change workflows

Whether you're upgrading from legacy models or starting fresh, the DTM-351 offers unmatched ease of use, high sensitivity, and robust performance—ideal for advanced scientific, industrial, and research applications.
