Fixed length, and check the hole size
This is the original-style sleeve at a fixed 43 mm x 16 mm. If the depth you need to test at does not match, the adjustable humidity sleeve is the alternative.
The 16 mm diameter dictates the drill bit. For sleeves requiring a 12 mm hole, see the 12 mm concrete drill bit; for 3/4 inch holes, the 3/4 inch masonry bit.
The seal is the test
The sleeve exists to isolate a pocket of air from the room so it can equilibrate with the material around it. An unsealed sleeve measures the room, produces a comfortable number, and tells you nothing about the slab.
