Product Introduction

Each instrument has been verified by the Central South National Metrology and Testing Center to ensure that its indicators fully comply with the standards of GB6566-2010 "Limits of Radionuclides in Building Materials", GB5101-2003 "Sintered Ordinary Bricks", GB13545-2003 "Sintered Hollow Bricks and Hollow Blocks", GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering", GB/T18883-2002 "Indoor Air Quality Standards" issued and implemented by the General Administration of Quality Supervision, Inspection and Quarantine of China. It can quantitatively analyze the content of gamma radioactive nuclides in various media such as building materials and their products, food, water, health disease control, environmental protection, geological samples, building materials quality inspection, marble, cement, granite, radiation protection, grain quality inspection, etc.
