Description of the pneumatic circuits
The LASER ONE samples using a membrane pump. The typical flow is 0.8 l/m and the minimum flow
is 0.7 l/m.
The use of accessories, such as the probes can slightly reduce this flow. It is advised to only use the
parts and accessories supplied by QED Environmental Systems Limited.
The sample inlet port is suitable for a tube with the dimensions ID2mm X OD4 mm.
An internal hydrophobic filter protects the device against any ingress from dust or water. An
additional external filter is also recommended which can help protect the internal filter.
Warning
The Hydrophobic filter is not design to filter anything other than water
or moisture; chemicals may damage the efficiency of the filter.
Please be vigilant when completing a survey and avoid sampling dust
and moisture, as if the filter is too saturated it, may result in serious
damage to the internal sensors.
Malfunction of the pneumatic circuit / Pump OFF
The instrument detects when the pump flow is within normal
operating parameters.
If the flow reduces below certain limits, the pump will stop, the
LEDs will light up, the pump icon will have a ‘X’ overlay and the
message "PUMP ERROR" will be displayed.
