An air sampling system for a low-temperature space is disclosed. The air sampling system includes an air sampling pipe for passing sampling air to an air sampling device, and a sampling conduit extending from the low-temperature space to outside the low-temperature space. The sampling conduit is connected to the sampling pipe. The sampling conduit is selectively accessible from outside the low-temperature space for removal of ice build-up within the sampling conduit. Also disclosed is a kit for an air sampling system. Also disclosed is a method, computing system, air-sampling device and air monitoring system that evaluates an air sampling network.

Air sampling system for a low-temperature space that enables removal of ice build-up within a sampling conduit

A particle detection system including a particle detector in fluid communication with at least two sample inlets for receiving a sample flow from a monitored region. The particle detector includes detection means for detecting the level of particles within the sample flow and outputting a first signal indicative of the level of particles within the sample flow. A flow sensor is located downstream of the sample inlets for measuring the flow rate of the sample flow and outputting a second signal indicative of the flow rate of the sample flow. At least a first sample inlet is normally open to the monitored region for receiving at least part of the sample flow. At least a second sample inlet is normally closed to the monitored region but is openable to the monitored region in response to a change in environmental conditions in the monitored region. The particle detection system further includes processing means adapted for receiving the first and second signals and comparing the first signal to a predetermined threshold level and comparing the second signal to a predetermined threshold flow rate, and generating an output signal based on the respective comparisons of the first and second signals. A method of particle detection is also described.
