Data Logger Tramex DL-RHTX – FeedBack

Tramex DL-RHTX Feedback DataLogger

The Feedback DataLogger and App log up to 100,000 data point entries for relative humidity, temperature, dew point and grains per pound, transmitted wirelessly via Bluetooth BLE technology to your mobile device. Used to perfom ASTM F2170 with the Tramex Hygro-2 probe.

Performing ASTM F2170

Having found the most suitable locations to perform the test (and following all necessary safety precautions), 3 tests should be carried out for the first 1,000sqft and 1 test for every 1,000sqft after that. Holes should be drilled to 40% of the overall depth when testing concrete which is drying from one side only (i.e. ground floor) and 20% of the overall depth when testing concrete which is drying from both sides (i.e. upper floors). RH sleeves are then placed into the bottom of the cleaned holes, cap and seal them and leave for 24hrs to allow the airspace inside each sleeve to achieve equilibrium with the RH in the concrete. After equilibrium is achieved, caps should be removed from each RH sleeve and Hygro-i2® probes should be inserted into each sleeve and allowed to acclimate to the internal environment. The probe should be at the same temperature as the concrete before taking a reading. When readings do not change by more than 1% RH over 5 min. equilibrium can be assumed.

Using the FeedBack App, reporting tests could not be simpler, the FeedBack is automatically recording the ambient RH & temperature, in-situ RH & temperature as well as the location, time and date being stamped by the App in use with a cellular device in one of two ways: Option 1: Reports can be given the title of the job site or room under test and readings recorded once the DL-RHTX is connected to the Hygro-i2® probe via the DL-RHIE cable (which is supplied with the FBSK5.1 or FBZK5.1 kits). Readings are recorded and added to the report page by selecting «Store Reading».

Option 2: Using the camera function at the initial device selection stage (before connecting to the selected DL-RHTX) at the bottom of the page marked «Device Selected». Takiing a photo of the DL-RHTX and selecting «Use Photo» will record a photographic image of the device with all readings as well as location, time and date stamp in the photo. This can be stored on the device or uploaded to a report. Watch this space for more articles and videos on how to make the most out of your FeedBack DataLoggers.
