Portable Stretch Scope - Model 79
Introduction

The Model 79 Stretch Scope provides the operator with the ability to investigate areas of suspected gamma contamination while remaining at a greater distance from potentially high fields of radioactivity. The 4.5 m carbon fiber telescoping pole allows the attached detector to reach areas difficult to access with other types of instruments, while its significantly reduced weight mitigates fatigue for the operator.

A large, easy-to-read LCD display rotates to maximize ease of viewing. Padded shoulder strap (included), piercing warning tone, and easy, intuitive design are also featured. The unit’s body is made of durable, high-impact plastic with a separate battery compartment. 

This versatile instrument has three modes of operation - RATE, MAX, and COUNT. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, spm, Sv/h, mrem/hr, and R/hr units. The user can choose between two sets of units by simply pressing the Units button. An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification. Setup is also available via software from Ludlum Measurements.
