EDX-7200 for High Speed,
New
High Sensitivity and High Accuracy

The EDX-7200 is equipped with a high-resolution SDD detector to achieve a higher count rate and detection efficiency.

High Speedɹ− Throughput Increased by Up to a Factor of 30 −
Equipped with a high-speed circuit that increase the count rate by up to 30 times compared to the former model (EDX-720).
Improved algorithms and improved performance also help to reduce measurement times.

Extending the measurement time to increase the fluorescent X-ray count can improve the precision (repeatability) of X-ray fluorescence
spectrometry.
The EDX-7200 incorporates a high-count-rate SDD detector and a high-speed circuit that achieves highly precise analysis of the target in a shorter
measurement time.
