- One button starts/stops data logging without a PC
- Plug-and-play USB 2.0 interface; no need for cables, cradles or docks
- Large storage capacity: 16,300 pairs of RH and temperature readings
- Two LEDs indicate device working status and "memory full"
- Included software is used to set: Sampling time from 10 seconds to 12 hours; Hi/Lo alarm setpoints for humidity and temperature; Temperature unit (°F or °C)
- Software also calculates and plots GPP and dew point and wet bulb temperatures and displays data logs as time based graphs synchronized to your PC’s clock
The DL-GT-HT08 is a low-cost, compact, battery-powered thermo-hygrometer capable of unattended logging (recording) of the ambient temperature and relative humidity (RH) of an environment for days, weeks or months. In addition, software included with the product can also calculate and display absolute humidity levels in units of grains per pound (GPP) or g/kg. Also called mixing ratio, GPP is a more useful moisture metric than RH to water damage remediators. Using RH alone, a remediator might unknowingly introduce moist air, with a low RH but a high GPP, during a job’s drying phase.
Data logging can be started or stopped by pushing a button on the unit, eliminating the need to bring a laptop to the job site. After a data log has been captured and stored, it can be uploaded as a .txt file to any PC running the Windows operating system after plugging the DL-GT-HT08 into one of the computer’s USB ports.
The DL-GT-HT08’s internal flash memory is large enough to store 16,300 pairs of RH and temperature readings.
Included with the product, which is slightly larger than a thumb drive, is a mini-disc with the drivers needed to interface the unit to the computer, as well as software that can display a data log file as a table or graph and/or export it to Microsoft Excel. Exporting to Excel is recommended for sophisticated trending and analysis of humidity and temperature data and easy detection of unexpected excursions.
