Tenmars TM-91 Geiger counter
The Tenmars TM 91 can measure background radioactivity and detect the radioactivity of different materials and products. The device detects radiation in the measuring range from 0.5 to 19.99 microsievert per hour. The alarm threshold can be set individually for the Geiger counter Tenmars TM 91.
If this alarm threshold is exceeded, the Geiger counter outputs an alarm signal. The required 9-volt battery is interchangeable and already included. The violin counter Tenmars TM 91 is suitable for private persons and authorities. It has also been successfully used in the medical, nuclear and metal processing industries for many years.
- Display units in uSv/h and uRem/h.
- Built-in a GM tube.
- Quick response to the radiation strength of
Beta(B), Gamma(y) and X-ray.
- Auto Ranging.
- Automatic detection, easy setting.
- A beeper chirps with each radiation count.
- Audio alarm setting function.
TM-91 & TM-92 Radiation Monitor are the survey meter in measuring the beta, gamma and x-ray radiation. 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 cargo inspections.
