Wide Range Surveymeter Type WR707 designed & manufactured by Nucleonix Systems serves as a dual range two detector surveymeter. A sensitive detector (external) covers lower range of 1µR/hr to 10mR/hr & second detector (internal) covers 1mR/hr to 1R/hr. At a time one detector only can be used.
State-of-art electronic circuitry designed around a microcontroller chip give stable and accurate readings, on a dot-matrix LCD display. |
Features
- Conforms to ANSI N42.17A performance specifications for Health Physics instrumentation (portable) &
 compliant.
- Instrument is compact, elegant and lightweight, and is designed around Microcontroller based electronic circuitry.
- The Instrument operates on an in-built battery supply of 6V DC. (dry cells)
- The Instrument can with-stand temp. upto 55oC & Rel. humidity upto 90%.
- Measures doserates upto 5R/hr
- Measures count rate in both CPS & CPM
- Accuracy +/-15% (Excluding background )
