Group3 DTM-350 – Precision 3D Magnetic Field Measurement, Redefined

 

Introducing the DTM-350, the newest evolution in Group3 Technology’s renowned 3-axis digital teslameter line. Building on the legacy of the DTM-333, the DTM-350 delivers higher resolution, reduced weight, and advanced real-time analysis—at a cost-effective price point for instrumentation design engineers who refuse to compromise on performance.

This is the ideal solution for research laboratories, industrial environments, and any application requiring high-precision 3D magnetic field measurement.

​

Key Advantages

  • Higher Resolution – Significant resolution increase over the previous DTM-333, enabling more precise 3-axis field characterization.

  • Proven Group3 Stability & Accuracy – Based on the award-winning DTM-151 single-axis platform, known for exceptional measurement stability.

  • Cost-Effective Engineering – Omits temperature reading circuitry for budget-conscious projects without sacrificing core measurement performance.

  • Lightweight, Compact Design – Just 3.5 kg, nearly half the weight of the DTM-333 (6 kg), making it easier to integrate into portable setups.

  • Custom LabVIEW™ VI Supplied – Includes ready-to-use software interface for USB connectivity, simplifying integration into automated test systems.

  • Real-Time Data Logging – Stream, record, and visualize all three magnetic field components simultaneously.

  • Custom Initialization – Save and recall preferred measurement settings instantly.

  • Graphical Representation & Vector Summation – Live 3D visualization plus automatic calculation of the resultant magnetic field vector.

  • 0.03% Basic Accuracy – Achievable when paired with Group3’s 3DT-132 or 3DT-230 precision 3-axis Hall probes.

  • Versatile Applications – Optimized for research, industrial quality control, magnetic mapping, and fusion or particle physics projects.
