A world standard

A range to over 13 Tesla, a precision of under 0.1 parts per million (ppm), an absolute accuracy of 5 ppm, and freedom of drift due to temperature or aging make the PT2025 the gold standard of magnetometers.

With more than 1700 Metrolab Precision Teslameters shipped, NMR magnetometry has become an everyday tool for physicists, engineers and technicians throughout the world. The most common applications include research, magnet manufacturing and testing, and standards and calibration. Some accelerator and spectroscopy manufacturers build the PT2025 right into their products.

High tech made easy

The industrial quality electronics and clearly organized front panel of the PT2025 make NMR magnetometry accessible to any technician. The large, bright field-strength display can be read from across the room. The green LOCK light clearly shows when the instrument has locked onto the resonance.

The field search may be performed manually or automatically. The probe selection switch directly controls an optional multiplexer, and an indicator panel shows the currently selected probe range. Finally, the signal-monitoring sub-panel allows the expert user to optimize the measurement.

The back panel provides connectors for power, a probe or, optionally, a multiplexer, and an RS-232 computer interface, optionally also GPIB.  The PT4025 3U rack-mount model allows one or two teslameters to be secured in a 19” rack.

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 range of 1.5 T to 13.7 T. Each probe has a range of 300% (proton) or 225% (deuterium), for example from 0.7 to 2.1 T, providing a generous overlap with the next-higher and next-lower ranges. The standard cable length is 10 m, but cable lengths of up to 100 m can be special-ordered.

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.

A full range of accessories

The model 2030 and 2031 multiplexers allow up to 8 probes to be connected to a single PT2025 unit. By adding a model 2032 “multiplexer of multiplexers,” this number can even be extended to 64 probes. The RG2040 NMR field regulation module controls a magnet power supply to provide closed-loop magnetic field control. The HS2060 high stability internal frequency counter provides the ultimate in long-term stability, and the model ACC-1060 and 1100 Gradient Compensation Coils may be used to improve performance in inhomogeneous fields. Finally, the CC2020 carrying case provides storage and safe shipment for a PT2025 and two probes.
