COMO Food Contamination Meter

Product introduction

Large amounts of radioactivity enter the human body through food ingestion. Many international organizations such as the World Health Organization and the International Atomic Energy Agency have issued recommendations regarding maximum activity concentrations of several radionuclides in food. GIHMMCOMO Contamination Monitors are designed to quantify radioactivity and identify nuclides in food and other materials. It is based on the GIHMM spectral gamma detector GSP02, and thanks to the large sample injection volume and the use of a 35 mm lead shield, COMO offers significantly better measurement results than similar products at an attractive price.

Main application

• food, milk, juice

• Pet food • Ingredients, soil

• Finished products, parts

• Test samples

• Waste, wastewater, sewage sludge
