Introduction:
The TM-91N radiation monitor is the survey meter in measuring the Gamma, Beta, X-Ray radiation with Geiger-Mueller tube. It is
useful in monitoring the environment home safety, nuclear, medical, mining and metal industries. It is also ideal for the border
control, customs and goods inspections. Measurements are displayed on a LCD monitor with low and alarm settings. The
measurement can be displayed in µSiever/h or µRem/h with a range of 0,01 µS/h to 20 µS/h or 1µRem/h to 2000 µRem/h. It is an
excellent device, high sensitivity, for living environments or industrial environments.
