Introduction to FD216 Environmental Radon Measuring Instrument:

FD216 Environmental Radon Measuring InstrumentIt is a measurement of radon concentration (optional) in ambient air, soil, water, and soil radon release rate (optional). It can be used for geological exploration, radiation protection, nuclear accident monitoring, radiation dose evaluation, earthquake prediction, and teaching.

This instrument complies with the measurement principles and requirements of GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering" (2013 edition) and GB/T16147-1995 "Measurement Method for Radon Concentration in Air by Scintillation Bottle".

Instrument features:

◆ Small size, light weight, easy to carry.

◆ High sensitivity, low power consumption, dual-use for both AC and DC

◆ USB data transfer interface, Bluetooth printing.
