The FJ-45WF-2 Water and Food Contamination Radioactive Detector is a monitoring instrument based on a sodium iodide (low potassium) detector. Designed to measure the specific activity of 137Cs and 131I radioactive isotopes in food and water (including various beverages), it provides rapid detection of radioactive contamination levels for households, enterprises, shopping malls, inspection and quarantine, disease control, environmental protection and other institutions.
The instrument features a highly sensitive sodium iodide scintillation crystal detector (45mm * 70mm) that delivers fast operation, accurate measurement, and high sensitivity. Its lightweight, ergonomic design includes a high-resolution LCD color display for simple operation and real-time detection capabilities.
