Wagner Meters Rapid RH® L6 Smart Sensors – Easy ASTM F2170 Concrete MoistureTesting for Flooring Installation – In-Situ RH Sensors, 5 Pack — Open-Box, 32% Off

ASTM F2170 COMPLIANT CONCRETE MOISTURE TESTING – Rapid RH L6 Smart Sensor refill packs make it easy to perform accurate in-situ relative humidity (RH) testing for concrete slabs before installing hardwood, LVP, vinyl, tile, carpet, epoxy coatings, or other floor coverings. Designed for contractors who already own a Rapid RH L6 Total Reader.

PREDICT FUTURE SLAB MOISTURE CONDITIONS – Unlike surface moisture tests, Rapid RH Smart Sensors measure relative humidity inside the concrete where moisture responsible for future flooring failures exists. Testing at the ASTM-specified depth helps installers make confident flooring installation decisions while reducing the risk of adhesive failure, cupping, mold, blistering, and delamination.

SAVE TIME ON EVERY JOBSITE – Factory-calibrated, single-use Smart Sensors eliminate recalibration and maintenance. Simply install the sensor, allow the required equilibration period, and take repeat readings in seconds using your Rapid RH L6 Total Reader. Leave sensors in place for convenient follow-up testing without removing or replacing them.

WIRELESS READINGS & DIGITAL REPORTING – Pair your Rapid RH L6 Total Reader with the free DataMaster L6 app to capture readings, organize projects, and generate professional moisture reports. Bluetooth data collection helps reduce paperwork, improve documentation, and simplify ASTM F2170 compliance.

COMPLETE REFILL PACK FOR RAPID RH L6 USERS – Available in 5, 25, 50, or 100 Smart Sensor Value Packs, each refill includes factory-calibrated Smart Sensors, extensions, protective caps with rubber plugs, stainless steel covers, a certificate of calibration, and a floor map. Keep your inventory stocked so you're never one sensor short of completing an ASTM F2170 concrete moisture test.

WORK SMARTER WITH THE EASIEST ASTM F2170 TEST – Designed for busy flooring professionals, Rapid RH L6 eliminates the hassles of reusable probes with factory-calibrated, single-use Smart Sensors. There's no calibration, no maintenance, no sensor swapping, and no waiting for re-equilibration, making it one of the simplest and lowest-cost RH testing systems available for ASTM F2170 concrete moisture testing.

This kit includes: 5 L6 Smart Sensors, 10 Extensions, 5 Protective Caps with Rubber Plugs and Butyl Gasket, 5 Stainless Steel Covers, a Certificate of Calibration, a Floor Map, and an Instruction Manual.
