END OF LIFE: After more than 30 years, the NMR Precision Teslameter PT2025 – the recognised gold standard of magnetometers – has reached the end of its commercial life. It is succeeded by Metrolab’s new-generation NMR Precision Teslameter PT2026, providing a 10x improvement for almost every performance parameter, at a comparable price. Certain probes and accessories are still available, and we continue to service existing units. Please see the End of Life Notice for details.

Different probes for different applications

Robust proton-sample probes are available for fields from 43 mT to 2.1 T, whereas deuterium-sample probes (heavy water in glass ampoules) cover the rangeThe range of a probe is defined by the minimum and maximum field strength it can measure.

The model 1062 probes provide a compact and easy-to-handle solution for general-purpose use. The model 1060 probes place most of the active electronics in a separate box – the model 1030 Amplifier – and are therefore appropriate for high-radiation environments. Finally, the model 1082 and 1080 subminiature probes are designed for installations with tight space constraints.
