STATE OF ART INSTRUMENTATION FROM AN INNOVATIVE COMPANY
micro-r-survey meter [ type : ur 705 ]  
Technical Data

Micro-R Survey Meter Type : UR 705 manufactured by NUCLEONIX SYSTEMS is primarily designed to measure low level Gamma and X-radiation. This Portable Survey Meter, designed around integrally coupled 1" x 1" NaI(Tl) Scintillator to a 1 1/2" PMT, will offer an optimum performance in counting Low-Level Gamma Radiation dose rate.

This unit can measure and display dose rates in the range of 0-10000 µR/hr on a dot matrix LCD Display. Dose rates close to natural background levels can be measured accurately.

This unit is ideally suitable for Radiometric and Environmental Radiation Monitoring involving low-level radiation dose rates.

This unit employs micro-controller based design and has number of unique features. User can store up to 1000 readings at the press of a button and can recall back, for visual indication on a dot matrix LCD display. This unit is provided with a built-in micro USB port (optionally) through which the stored data can be down loaded into PC.
