To do this, moisture sleeves with adjustable heights are inserted into the material; these sleeves house the newly developed mini-hygrostick moisture sensors. Based on the moisture values measured in the material, a conclusion can be drawn regarding the amount of excess water contained in the material. A moisture level above 80% clearly indicates the need for further drying. If the value is below 75%, the floor is generally considered ready for covering. For values below 75%, measured over a 24-hour period, the floor can generally be certified as ready for covering. Follow the installation instructions provided by the manufacturers of floor coverings and leveling compounds, as well as applicable regulations and standards.      <\/p>\n<p>The advantage of the new humidity sensors: they can remain in the sleeve until the next measurement, sealed airtight and protected by a cap. This eliminates long wait times for each subsequent measurement, since the sensor has already \u201cacclimated.\u201d To insert the moisture sleeve, drill a hole in the floor using a drill bit of the correct diameter. The floor kit includes a concrete drill bit with a suitable depth stop. The moisture sleeves are adjustable in length, so measurements can be taken only at the desired depth. Between measurements, the sleeve is sealed airtight with a cap. The moisture sensor can remain inside the material and is protected.      <\/p>\n<p>To read the measured values, the MMS 2 is connected to a humidity sensor with an extension cable. For repeat measurements, the values can be read without a long wait. <\/p>\n<p>The probes are then removed from the sleeve using a lifting tool before the hole is sealed. The user can check the calibration of the humidity sensors using the included bottle of salt solution. If necessary, used sensors can be quickly replaced.   <\/p>\n<p><strong>Floor Layer Kit Contents:<\/strong> MMS 2 moisture measurement system, Short-Quikstick moisture sensor, test resistor, 5-piece
