Stretch Scope - Model 78-1
The Model 78-1 Stretch Scope telescoping gamma survey meter keeps the user at a safe distance from high rad areas, and reaches areas otherwise difficult to normally access. The wide 1 µSv/h to 9999 mSv/h detection range is accomplished using dual energy-compensated GM detectors. The backlit digital LCD delivers precise 4-digit measurement values, which can be programmed to display units of Sv or Counts, and is accompanied by icons and messages for operational status of the instrument. Rate changes are conveniently viewed on the accompanying analog meter. The front-panel controls include separate switches for On/Off, Audio, µSv/h & mSv/h range selection, Fast/Slow response, and LCD backlight. An adjustable clip-on shoulder strap is included. The handle may be removed thereby reducing the collapsed length from 105.9 cm (41.7 in.) to 92 cm (36.2 in.) for easier transport and storage of the instrument.
