Radiation Dose Rate and Dosimeter
Product Code: NEB.211
NEB.211 Radiation Dose Meter Device
- The NEB.211 is a portable, handheld device suitable for measuring radiation dose rate and radiation dose. It is widely used in Health Physics applications, laboratories working with radioactive materials, and industrial applications involving radioactivity.
- The NEB.211 utilizes a microcontroller according to modern technology. This feature reduces measurement errors, especially at low levels, and allows for simultaneous measurement of both radiation dose rate and radiation dose.
- A beep sound is produced for each radioactive particle or radiation that hits the detector, making this feature suitable for monitoring low-level radiation.
- It has an audible alarm feature that can be adjusted for radiation dose rate or radiation dose.
- The device has a self-test feature, and malfunction conditions are displayed on the device indicator.
