Protimeter Adjustable Humidity Sleeves — 50 Pack
Fifty adjustable sleeves. The sleeve holds a mini Hygrostick at a set depth inside a drilled hole and seals it, so the air around the sensor equilibrates with the slab rather than with the room. Without a sealed sleeve the reading is of the room, not the concrete.
Which pack size
Sleeves are the item consumed on every test. ASTM F2170 calls for three test locations in the first 100 m² and one for each additional 100 m², so a single commercial floor can use a dozen. The 50 pack is the working quantity for a contractor doing this regularly; the 20 pack suits occasional testing.
Matching the sleeve, the hole and the sensor
Three sleeve systems exist and they are not interchangeable. The sleeve has to seal in the hole, or the air inside it equilibrates with the room instead of the slab and the test is meaningless.
