Yes, you can add or remove test cartridges while other tests are running.
The Tectalert EC/TC test has a limit of detection of 1 CFU/100 mL for E. coli and 1 CFU/100 mL total coliforms in drinking water.
The Tectalert test cartridges have a shelf life of 15 months from the date of manufacture. Recommended storage conditions are 5°C–30°C and less than 60% humidity.
Periodic chamber verification is required and can easily be completed by trained personnel using the supplied validation cartridge.
