This is the web site of a particle counter at IPGP - Distillation clean Room

It works! Thanks to the peple living here.

This is the on line system interface of particle counting placed in the, distillation clean room of IPGP of ambiant air (1/10 cft per min). Graphs are ploted in number per cubic meter witth a square root mass scale. ISO5 and ISO6 threshold levels are indicated ISO5 level for 5µm diameter particle is also indicated.

ISO 5 levels:

• 0.5: less than 3520 per cubic meter
• 5: less than 29 per cubic meter

You can change ISO +1 by multiplying by a factor 10

The GPS position of the sampler is at IPGP, Paris
