AirSPEC is a monoblock unit, comprising scintillation crystal, photoelectronic multiplier, HV converter, amplifier, multichannel pulses analyzer and processor unit.
AirSPEC 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.
AirSPEC 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.
AirSPEC provides an additional feature of thermostabilizing housing to provide a wider range of operating temperatures. The housing provides both high degree of thermal insulation and automatic control and active adjustment of the temperature inside the device. The IP67 degree of protection allows to use AirSpec in severe weather conditions.
