Lignomat RH-20S, RH Concrete Moisture Meter Standard Testing Sleeves (20 Pack)
Standard Sleeves
Hole liner for RH in-situ concrete moisture testing.
If necessary, sleeves can be cut shorter.
Top Extenders can be added to seal off the probe. See description below. The lip of the shortened sleeve can still be installed flush with the concrete to form an excellent seal.
Sleeves and blue caps, length 1.8″ (4.6 cm)
Top Extenders for standard Sleeves
The top extenders are needed, when the sleeves have to be shortened and the RH BLuePeg Probes are sticking out above the concrete. The top extender fits into the lip of the sleeve and seals off the RH probe. The blue hood is removed to take readings.
