WaterSpec is a monoblock unit, comprising scintillation crystal, photoelectronic multiplier, HV converter, amplifier, multichannel pulses analyzer and processor unit.
WaterSpec measurement system is autonomous, automated and provides calculation of the ambient equivalent dose rate H*(10) in real time, as well as identification of the most common natural and artificial gamma radionuclides. The results of the identification and dose rate are then transmitted to the upper-level computer via exchange protocol.
WaterSpec has automatic stabilization of the spectrometry channels by means of tracking the position of the K-40 1460.8 keV full energy peak provided by the potassium salt located in the cartridge near scintillation crystal.
WaterSpec is designed for indoor or outdoor use in aquatic environments. The waterproof housing has IP68 degree of protection: dust-tight (full protection against dust and other particulates) and protected against extended immersion in water to a maximum depth of 2 meters.
