| == Filter paper ==
| |
| H: Filter papers – Type TBD, tested with Pall T60A20 – ask local labs for availability<br> This is crucial, tell us what type you use, send us a sample and we find the correction factor to use. [[Filter_paper_correction_factor|Refer to Correction factors for different filter papers]]
| |
| | |
| Basically any filter works, the device just has to be calibrated against it.
