Long-term Blaine test stability depends most on the permeability cell, the air path, and repeatable sample packing. For this digital Blaine apparatus, the best maintenance focus is keeping the cell clean and sealed, the tubing and fittings tight, the filter papers in good condition, and the lab environment steady so results stay comparable over time.

In practice, the items that matter most are clean permeability-cell parts, leak-free tubing and fittings, fresh filter papers and packing tools, and regular checks with reference cement to confirm the method is still tracking as expected. The product page also notes a stable indoor temperature range and minimal drafts, which helps protect Blaine fineness repeatability.
