HORIBA PA1000 Environmental Radiation Monitor

HORIBA PA1000 Environmental Radiation Monitor is emitted continuously, day and night, from various objects and substances in the natural world and our living environment. Most environmental radiation consists of three types: alpha rays (α), beta rays (β) and gamma rays (γ).  HORIBA’s PA-1000 ‘Radi’ environmental radiation monitor makes it easy for non-specialists to measure even minute levels of gamma rays.

Features :

Easy measurement by Anyone, Anytime, Anywhere
Designed with plant-based plastic material helping to reduce petroleum consumption
High performance detection with a CsI (Tl) scintillator
The Radi can measure radiation levels ranging from normal natural radiation to levels 100 to 200 times that intensity. Even non-specialists will find it easy to measure radiation of 0.001 – 9.999 µSv/h.
Splash-resistant construction
The Radi can be used with confidence even if there are water droplets on the surface. (JIS water resistance protection grade IPX4)
Compact and lightweight (175 g / 6.2 oz)
Uses two AA batteries.
Battery life 50 hours or more (when manganese dry cell batteries are used)
