Extech's SDL720 gives you everything you need to measure and log pressure levels over a period of time.
A portable, datalogging pressure meter, the Extech SDL720 stores a huge range of records on a supplied SD card, complete with date/time stamps for easy referencing. Data can be seamlessly transferred to a PC in Excel format, with no specialist extra software required.
The SDL720 is classed as the mid-range model in the SDL700 series. It has a wider measurement range than the SDL710 (up to 2000mbar or other unit equivalent) and generates consistent, accurate results at all times. You can also switch between 10 different pressure measurement units as needed.
Additional features of the Extech SDL720 manometer include a MAX/MIN mode, data hold function and a zero function for offset corrections and measurements.
