JL-900 Snow White is a high volume air sampler produced for continuous outdoors use with specialised models for a range of ambient conditions; from tropics to arctic. Snow White has been proven to be able to operate in the tropical rain as well as in the heavy snow storm. Standard Snow White version is designed to work down to -25°C. For the harder conditions (-40°C) we produce models Snow White.cold or Snow White.Arctic.
The high flow rate of up to 900 m³/h allows for low level analysis in the micro-bequerel range. Snow White is one of the most accurate high volume air samplers in the world. Snow White is also one of the few commercially available samplers that has been tested and approved in wind tunnel for global collection efficiency (CTBTO). All models can be equipped with a separate calibrated activated carbon line to enable sampling gaseous substances.
