This detector can be widely used in environmental monitoring and industry, etc. 

There are three detection modes: real-time dose, average dose and cumulative dose.

The small size of this tool is very convenient for everyday use.

Real-time dose (REAL): Update once a second to quickly show the true value of each moment, which is characterized by high fluctuation and high compatibility with sensor detection results.

The real-time value is automatically checked and displayed.

Average dose (AVG): the resulting measurement is converted over a period of time to an average value. Press the M button to recalculate the average value.

Accrued dose (ACC): that is, add all detected doses and the data will not be lost after shutdown, and the accumulated data will continue to be saved.

You can simultaneously press the L and R button to clear the memory.
