Some procedures added


Hello everybody,
Some repair and troubleshooting procedures were recently added online.
You can find them here:
https://www.airpointer.tech/howto/
The list is not exhaustive, but there are already a lot of helpful documents. The Airpointer is always evolving, and therefore so are the procedures.
Keep an eye on airpointer.tech, and if you don’t find what you need, do not hesitate to contact the MLU-Recordum support team for help!

To calculate the concentration of a perm tube

Hello everybody,

Because several people asked me during the training, below is an excel file calculating the concentration of a perm tube using the permeation rate and the flows, and converting the concentration from micrograms per cubic meter into ppb:

How do I know which Airpointer housing I need?

Hello everybody,
The Airpointer housing comes in 3 different sizes: 2D, 4D, and HC. Some housings can hold a PM monitor, others can’t. Some can handle very high outside temperatures, but not all of them. Some can have 2 analyzers in one drawer, but it depends on several parameters…

You are confused? Then go to https://www.airpointer.tech/airpointer-base-unit/, download the excel file, answer the 4 questions, and it will tell you what you need.

Regards,
Kevin.

And the pneumatic diagrams, also for the base units and for the 5 most common airpointer modules (O3, CO, SO2, NOx, H2S):
