Metrolab PT 2026
NMR Precision Teslameter

Nuclear Magnetic Resonance is the most precise technology to measure magnetic fields, and the PT2026 is the most precise NMR magnetometer on the market. In optimal conditions, it achieves a precision of under ten parts per billion!

But precision is just one of the features brought by the PT2026: high fields, robustness to inhomogeneous fields, 33 Hz measurement speed, improved search time – the list goes on. The key is an instrument design, using modern RF and computer technology. The result is an NMR magnetometer that opens up a host of new application areas.

Pushing back physical limitations

The PT2026’s astounding precision is due to a pulsed-wave (PW) NMR detector and advanced signal processing. It allows measuring minute effects such as the decay of the current in a superconducting magnet.
The PT2026 delivers unmatched measurement range and precision. It measures magnetic fields from 38mT to >30T at a precision of 10 ppb with the use of pulsed-wave NMR detection.
A physical limitation of the NMR technique is diminished performance in inhomogeneous fields. The PT2026 pushes back this boundary with an increased tolerance to field gradient. The instrument is capable of searching and detecting the NMR signal in a gradient of 1.35 mT/cm in a 1T field (1350 ppm/cm).
The PT2026 allows measurement rates of up to 33 Hz.

Pushing back the spacial limitations

The probe 1426-thin, features a small measurement head connected to the probe electronics by a coaxial cable. This allows access to gaps down to 1.5 mm, “Yes, one point five millimeters!“, and is ideal for high-radiation environments.

Fitting into the laboratory

The PT2026 provides USB and Ethernet interfaces, and supports the industry-standard USBTMC/USB488 and VXI-11 protocols.
The included software provides a powerful user interface, right out of the box. Or you can write a custom application, using National Instruments LabVIEW®and the included driver. For other programming languages, you can send industry-standard SCPI commands (Standard Commands for Programmable Instruments), using any standard VISA library.
You can use the PT2026’s trigger-in capability if you need to trigger a magnetic-field measurement at a precise moment in time. Alternatively, trigger-out allows you to trigger another instrument when the field reaches a given value.
And if you have a high-precision 10 MHz reference clock in your laboratory, you can plug it directly into the PT2026, thus overriding the internal time base. This also obviates the need for periodic calibration.
