Senis 3MH6 High-Precision, Low-Noise Teslameter

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 Basic, C, C++, 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 and Cable (Module H), and
2. Electronics (Module E).

The Low-Noise Digital Teslameter is a high accuracy temperature-stabilized instrument for the precise measurement of magnetic field.
Each Transducer is calibrated with the individual correction data for the connected probe, so the probe is replaceable.
