This portable Thermo-Hygrometer displays RH / ambient temperature / dew point / wet bulb and thermocouple probe temperature on a large multi-line, backlit LCD. Fast response with high accuracy. Automatically record and store up to 32,000 data points per parameter. Wireless Bluetooth® transmission eliminates the need to remove the meter to the computer to download data. Previously recorded or real-time data can be streamed to the computer software or phone app from up to 100 feet away.

You may also manually record 100 data points directly from the keypad. User adjustable auto power off timer, audible and visible Hi/Lo alarms, min/max/avg, hold function, and fold-out easel back. Comes ready to use in a protective foam-lined case, with four AAA batteries, type K beaded wire probe, bi-directional USB computer/power cable, free downloadable computer software and free Android (version 4.4 “KitKat and above”) and iOS phone Apps. Will also communicate with your computer via the USB cable. N.I.S.T. traceable Certificate of Compliance available.
