Applied Data Sciences / USB THB
Portable USB Weather Data Collection Unit

The USB THB is an industrial, high precision, remote powered, hand held, pocket size weather data collection unit. It contains a barometer, thermometer and hygrometer. The unit can send real time, polled weather sensor data to a PC laptop or desktop computer via its USB port. The USB THB is also an ultra low power device. The unit receives power via the USB cable and the laptop or desktop computer that is attached.

The USB THB is rated for the industrial temperature range -40°C to +125°C (-40°F to 257°F)

NOTE: The USB THB is not waterproof so it must be shielded from direct contact with water. The Microsoft Windows Operating System [2000/XP/XP(64)] software performs other calculations; such as air density, relative air density, density altitude, and etc.

The selling price is US $159.00 for the USB THB, 1 meter USB cable and Windows software. The shipping cost is $9.00 USPS Priority mail excluding AK & HI.

We accept PayPal.
