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 alarming Survey Meter is designed around integrally mounted 1" x 1" NaI(Tl) Scintillator to a suitable 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 micro-R/hr 0 -100.00 mSv/h on a dot matrix LCD Display and has auto ranging facility. 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 microcontroller based design and has number of unique features. User can store upto 1000 readings and can recall back along with time stamp, for visual indication on a dot matrix LCD display. This unit has preset alarm facility which can be set throughout the range of the instrument. This unit also has a built-in RS232 port through which the stored data can be down loaded into PC. This unit has built-in preset alarm facility.
