Transportable ESR(EPR) measurement system

Model No. ESR04

ESR04 is a very compact, easy-to-handle desktop ESR/EPR (Electron Spin Resonator) system with higher sensitivity than standard X band ESR/EPR (Electron Spin Resonator) system. Adoption of a rare earth permanent magnet realized the miniaturization with a weight of about 27 kg.  An optional automatic liquid transmission unit will allow you to perform mixed measurement and analysis of a solution sample under PC control. ESR04 will also expand the field of ESR applications by leaps and bounds, including process monitoring, desktop ESR sensing by PC on hand and remote control.

Single purpose use – Magnetic field and frequency can be custom designed according to your specific purpose.
