11.0 Interpreting theResults
Figure 5 illustrates the LeakDetector’s LED light response
range. The greater the number of redor yellowLED lights lit
correlates in general to the size of the leak.
NOTE:
The Leak
Detector is not a quantitative device, rather it is designed to
detect leaks in gas line connections commonly associatedwith
laboratory equipment
**This unit is NOT designed for determining leaks of combustible gases. A combustible gas detector should be used for determining combustible gas leaks in a
hazardous environment.
