Wagner Meters WFP400+ C Concrete Moisture Test Starter Kit

Wagner Meters WFP400+ Series Rapid RH L6 Professional Flooring Installer Kit

The WFP400+ Rapid RH® L6 Professional Flooring Installer Kit provides everything you need for fast, accurate moisture testing of concrete, wood, and other wood building materials.

The Orion® 950 Moisture Meter, with its pinless design and protective rubber boot, quickly and easily takes moisture readings without damaging wood floors.

The Rapid RH Smart Sensors and Total Reader® enable fast, accurate RH and temperature readings from both the concrete slab and the ambient air.

The improved protective caps completely cover the test hole and seal it with a butyl rubber gasket. The integral access cover pulls off for quick access to the Smart Sensor and snaps back on to seal out water and dirt.

The Smart Logger™ automatically records ambient RH and temperature readings on-site while you’re away. Download readings from the Smart Logger using the free Smart Logger app and any Bluetooth®-enabled mobile device.

Each Smart Sensor pack comes with a NIST-traceable calibration certificate and comes in tamper-resistant packaging to ensure perfectly calibrated, genuine Wagner Smart Sensors.

Simplest F2170 Test

The Rapid RH method is simple and quick. Just insert the Rapid RH into an installed L6 Smart Sensor and get a reading instantly with Touch-n-Sense™ technology. On contact with any L6 Smart Sensor, the powers up, takes a reading, and holds the reading for up to 1 minute after it is removed from the Smart Sensor, then powers down – all automatically!

Improved Responsiveness in High RH

The Rapid RH L6 concrete moisture testing system features advanced technology that provides relative humidity readings with unparalleled accuracy even into the 90%-100% relative humidity range.

Integrated Data Storage

When paperwork may not be the most reliable option, the Rapid RH L6 system and DataMaster™ L6 app lets you collect, transfer, store, and report concrete moisture readings with tamper-resistant technology that ensures data integrity from collection to distribution. Each Rapid RH L6 Smart Sensor is NIST*-traceable and comes with documentation to comply with ASTM F2170 requirements.

Why It Is Crucial to Measure the Moisture Below the Surface of the Slab

Calcium chloride is, therefore, only a surface test, highly affected by ambient conditions in the room or building. Even if done correctly, a calcium chloride test tells you nothing about what’s going on deeper in the slab.

There is no ASTM standard for using moisture meters as a final determination of whether a concrete slab is ready for a floor covering.

Moisture meters should NEVER be used to make the final determination as to whether or not a concrete slab is dry enough for a flooring installation.
