A new generation transmitter series, PTU300, combines the ability to take barometric pressure, relative humidity, and temperature readings in one unit. It features fully digital measuring electronics for all three parameters and calculated humidity variables. For added reliability, two barometric pressure sensors are available. The new backlit display shows three-hour graphical trends and up to one year of historical data. The recorded measurement data can be viewed on the display or transferred to a PC. Seven language options are also available. The PTU has four different probe options: PTU301 for laboratories, PTU303 for outdoor use, the warmed PTU307 probe for demanding meteorology, and the PTU30T for pressure and temperature measurement only.
