Buying Guide

Alarm and audio feedback

Click alarms or adjustable audio feedback, like the MOESAPU FS-600's click alarm feature, make changes in radiation level obvious to a classroom without relying solely on numeric displays

Display clarity and readouts

An LCD display improves visibility in group settings—look for models with large digits and straightforward units (CPM, μSv/h) to avoid confusion during demos

Portability and power options

Handheld, lightweight meters with rechargeable or common-battery options simplify lab logistics; consider rechargeable models for frequent classroom use

Supported radiation types

Confirm the detector’s sensitivity to relevant radiation for your demos—many handheld units detect beta, gamma and X-ray; ensure the model matches your planned activities
