Senis 3MH6-E High-Precision Teslameter with Interchangeable Hall Probes

Low Noise Teslameter with integrated Hall probe incorporates a high accuracy magnetic field-to analog-voltage transducer with a high-level, temperature compensated output signal for each of the three components of the measured magnetic flux density: Bx, By and Bz. A digital module is additionally applied to the analog transducer to form the digital Teslameter. Digital Teslameter provides the possibility of automatic data acquisition via a USB serial interface by a
host computer. In this way, customers can easily integrate a measurement routine into their measurement system using its programming tools such as C, C++, C#, Python, Delphi, LabVIEW, etc.

The temperature measurement feature allows user to obtain current temperature values while monitoring the magnetic field.

The transducer consists of two modules:
1. Interchangeable Hall probe with various cable length (Module H), and
2. Electronics (Module E).

The Low-Noise Digital Teslameter is a high accuracy, temperature very stabilized device for the precise measurement of magnetic field.
Each Teslameter is calibrated with the individual correction data for the connected probe, so the Hall probe is interchangeable, by keeping the same accuracy of 100ppm.
