SSN-71 air pressure, humidity and temperature data logger measures and stores up to 32000 air pressure (300~1100hPa), temperature (-35 to 80℃(-31~176℉) and humidity (0 to 100%RH) readings. Logger status, alarm indication and low battery indication are via flashing red/green LED and yellow LED. The button on housing can be used to start logging, or confirm and clear LED alarm when LED alarm is hold status. Software can run under Windows XP, Vista, 7 or 8(32 bit and 64 bit Versions).
