Designed for integrity testing of membrane filter systems, the Sartocheck 4 plus features an optional scanner to enable information to be read into the test unit. This permits Sartocheck 4 plus to automatically capture all important data directly coded on the respective filter cartridges as data matrix code, such as filter type, lot number, and date of expiration. Immediately after the data of a filter cartridge has been scanned in, the integrity test system automatically selects the right test program from its database. The unit also features automatic detection of errors in the test equipment set-up, such as a disconnected filter housing. Additional units connected to the Sartocheck 4 plus permit users to run independent parallel tests of up to five different filters.
