Product Description

The WFP350+ Rapid RH L6 Advanced Concrete Moisture Test Kit with DataGrabbers provides everything you need for fast, accurate moisture testing of concrete.

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 L6 DataGrabber automates data collection and transmits data to the free DataMaster™ L6 app without the need for the Total Reader. Snap it into the L6 Smart Sensor, then use the DataMaster L6 app to set up a schedule for data collection. Use the free DataMaster L6 app to collect data directly from all DataGrabbers within Bluetooth® range. (The DataMaster L6 app requires iOS 10.0 and Android 7.2 or later.)

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. (The Smart Logger app requires iOS 10.0 and Android 4.4 or later.)

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.

Each Rapid RH® Starter Kit is carried within a water-tight and dust-proof hard case built to military specifications. ATA 300 rated and 2.8 times stronger than the competition, the iSeries hard cases from SKB are made in the USA and built to meet or exceed MIL-STD-810G, MIL-C-41503, DEF-STAN 81-41, and IP67 standards.

DataMaster™ L6

Datamaster IconThe DataMaster™ L6 is a free multi-purpose app for data recording and reporting of Rapid RH® L6 Smart Sensor readings. In addition, when paired with the new DataGrabber®, the app allows for automatic, periodic reading collection and storage. The DataGrabber with Bluetooth® features a built-in wireless connection to the app. The smaller DataGrabber connects by using the Total Reader® as a Bluetooth conduit.

DataMaster L6 improves upon the incredible utility of the DataMaster 4.0/5.0 app by streamlining the navigation to data and reporting functions as well as adding new features to program DataGrabber automated data logging devices. For the first time ever, DataMaster L6 is the facilitator of an unbroken stream of data from sensor to final report ensuring the highest degree of data integrity. The DataMaster L6 app connects via Bluetooth to the Total Reader and DataGrabber automated data logger devices to give you these great benefits:

  • Bluetooth link to DataGrabber devices to download stored L6 Smart Sensor time-stamped data, set time intervals for automated periodic concrete RH readings, and more.
  • Download, assemble, and email all data necessary to adhere to the ASTM F2170 standard.
  • Ensure the integrity of your critical ASTM data from sensors and email “READ ONLY” reports.
  • Link all recorded data to your job site’s sensor locations with a mapping function.
  • Input job metadata such as job name, address, and hole depth.
  • Add photos, audio memos, and text notes to your job info.
  • Print reports directly from your smart device.
  • Easily upload your job data to the website.
