Electronic Radon Monitor
Application
Fields Measure radon concentration in ambient air, soil and water and radon exhalation rate in soil and building materials. It can be applied in geological prospecting, radiation protection, nuclear accident monitoring, radiation dose assessment, earthquake prediction and teaching, etc.
Instrument Characteristics
Detector: PIPS detector.
Energy spectrum analysis of electrostatic collection of pumping gas.
High α energy spectrum resolution, high sensitivity and real-time display of spectrum data.
Fast measuring response and short recovery time.
Constant flow sampling. Small size, light weight, suitable to carry.
Low power consumption, AC/DC double use.
With USB data transfer interface, equipped with a Bluetooth printer.
