Underwater gamma energy spectrum measurement system

Product introduction

SARA marks the beginning of a new era of radiation monitoring, ENVINET, with its completely innovative product series, provides solutions for spectroscopic online monitoring of ambient gamma radiation in water, meeting for the first time all unaffected conditions under the harsh operating conditions of continuous use in seawater or freshwater Limitations on automated remote monitoring requirements. SARA series underwater gamma energy spectrometer is an underwater environment gamma energy spectrum detection system with autonomous operation function, which is used to obtain and analyze gamma energy spectrum in water online. Calculate the total gamma activity and total gamma dose rate and activity of each isotope.

Features

• Rugged (IP68 / IP69K, maximum water depth 500m);

• Optional GM tube and high dose rate detector to extend the measurement range;

• Isotope alarm management;

• Detector overload protection;

• Built-in Wi-Fi for wireless transmission.
