ER-100
   
The Model ER-100 is a complete, portable radiation monitoring system for measuring moderate levels of gamma dose (10R/hr) and most types of radioactive contamination.
Designed to measure a moderate range of radioisotope contamination & dose under field conditions.
ER-200
   
The Model ER-200 is the ultimate, portable radiation monitoring system that can measure dose from micro R to 1000 R/hr & most types of radioactive contamination.
Designed to measure a broad range of radioisotopes, contaminations and high levels of gamma dose under field conditions.
ALPHA-300
The ALPHA-300 is a portable, high-sensitivity system for measuring low levels of alpha (uranium, thorium) and other alpha emitting materials in the field.
Utilizes scaler, sample holder & zero background detector. Measures very low levels of most common alpha emitters in the field.
