Wagner Floor Sentry Wood Floor Data Logger


The Floor Sentry® embedded wood floor data logger is a card-sized device featuring temperature and relative humidity (RH) sensors to monitor and record up to 16,000 internal temperature and RH readings within your wood floor as well as the temperature and RH on the surface of the concrete subfloor or underlayment. Floor Sentry connects, via Bluetooth, to the free Wagner Sentry app for instant monitoring of floor or underlayment conditions, setting alarm threshold levels, viewing graphed progress, and more. This device can protect your installation liability and your wood floor investment.
