This Apple software is used with the Phoenix Sensors WEPS04 Pressure and Temperature transducer. It allows users to monitor up to 4 sensors at one time, with update rates as fast as 5 milliseconds (200hz). It displays both pressure and temperature information for observation. The software also allows the user to synchronize all four sensors to within 25 milliseconds of one another. The user may also save data to the Apple device as a .CSV (comma delimited) file where one can analyze the data in an excel spreadsheet (or similar).
