SAPHYMNO Geiger Counter MINITRACE β CSDF

SAPHYMNO
MINITRACE β CSDF 3-Unit Measurement Geiger Counter

This is a professional 3-unit measurement Geiger counter designed to enhance the safety of individuals working in controlled areas of nuclear power plants, reprocessing facilities, research institutions, and hospitals, as well as in police, fire departments, and military organizations. It has also been selected by électricité de France (EDF).
Its extremely simple operation allows for easy detection of potentially contaminated spots.

Purchased from Fujitex online store in 2011 (I believe the price was around 200,000 yen). It has been stored with little use since then. I estimate it has been taken outdoors less than 5 times. It offers a completely different level of stability and peace of mind compared to simpler models.
*Operation confirmed.
