RLGD-100 REMOTE LASER GAS DETECTOR
12
NOTES:
1.
A few factors that could possibly affect the detection: 1) extremely low methane may not able to be
detected; 2) Meteorological conditions (like strong wind or high temp) may cause quick dissipation of
the leak that not able to detect; 3) Condensated droplets on the lens due to severe temp difference
may impact the capability of detection.
2.
Make sure that the survey objective is able to reflect infrared light.
3.
Make sure that the alarm limit is set to meet safety detection needs.
4.
Try to set offset value as close as possible to actual ambient methane, to minimize its influence.
5.
An over-reflective objective may cause false alarm, check if light intensity is too strong, according to
which adjust detection angle to avoid over reflection.
6.
The instrument may false alarm on the pipeline that is too thin (<10mm) possibly being penetrated
and detected actually the gas passing inside.
7.
Please check if the time display right during every power-on of the instrument.
Tips:
1.
Move steadily and scan smoothly, manage a relative slow moving rate.
2.
Use adaptive scanning paths for specific survey areas. Scan known areas (like pipelines, or locations
where fixed gas detector employed) in ‘S’ path and unknown areas in ‘X’ path.
3.
How to locate precisely the leak point? Survey the suspect area at a best possible position, if alarms,
do it repeatedly, meanwhile minish scanning scope and scan around till locate the point where alarm
continues.
