Portable Radiation Tester Digital Backlight Dose Alarm X/ γ/ Hard β Ray Detecting Current & Cumulative DER Display Geiger Counter Dosimeter Monitor for Electromagnetic Field Factory Steel Mineral Stone Detection ( Item#: E21093 )

Dose alarm is mainly used for radiation protection monitoring of X, γ and hard β rays, it's suitable for factory, high-altitude/ ionizing/ nuclear radiation environment, steel/ mineral/ stone detection and more fields that need radiation monitoring. It adopts sensitive GM tube and can measure current and cumulative Dose Equivalent Rate (DER). With preset alarm, it's more humanized and ensures safety when using.

Features:
This portable dose alarm adopts high sensitivity GM sensor (Geiger Counter) and advanced chip, it's suitable for detecting X-ray, γ-ray and Hard β-ray.
Dual display of Dose Equivalent Rate (DER): current and cumulative. And the dual alarm values can be preset, with sound and light alarm for more humanized use.
Clear digital display with backlight, easy to read even in dark environments; English and Japanese switchable. 4 AAA batteries (not included) operated, easy to install and replace batteries.
Control buttons bring easy operation, 3 detecting units switchable (μSv/h, μGy/h, mR/h). Compact and lightweight, convenient to carry with you.
It can be widely used in radioactive environment, factory, high-altitude/ ionizing/ nuclear radiation environment, steel/ mineral/ stone detection, Iodine 131 detection and so on.

Note: Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
