Professional Supplier of Laboratory Scientific Instruments
The DA-15A multifunctional radiometer is designed for nuclear medicine, molecular biology laboratories, nuclear material transportation and other aspects where there are α, β surface contamination and X, γ radiation according to the requirements of ionizing radiation protection. It is a high-sensitivity Intelligent portable instrument. It combines the functions of a surface contamination monitor and an X, γ dose rate meter. It can be used to measure both the surface contamination caused by αβ and the Xγ radiation dose rate. For α and β\γ measurement, the display can be switched, and the measurement is operated by the handle button, and the measurement unit is cps\cpm\Bq/cm2 can be converted.
