Ⅰ.Product Introduction
TK-217 is a new hand-held radiation survey meter designed for detection of neutron and gamma radiation at the same time. Its neutron detector and gamma detector are 6LiI (Eu) and CsI (Tl) scintillation crystal respectively coupled with photodiode. The neutron detector is surrounded by unique cylindrical moderator which greatly improves the sensitivity of neutron detection.
Ⅱ. Main Features
l Independent neutron/Gamma detection channel and independent alarms
l Freely switch between three detection modes of counting rate, dose rate, accumulated dose
l High-definition LCD with backlight
l Audible, visible and radiation icon alarms simultaneously, alarm threshold is continuously adjustable
l Several shortcut keys make operation easy and convenient
l Electro-magnetic interference immunity, CE compliant
l Compliant with ANSI N42.35 and ITRAP standard
