The BAC-PAK is a test kit designed to allow field testing of wet pipe sprinkler systems and/or water supplies for MIC causing bacterium. The kit allows field testing for iron related bacterium (iron-pipe oxidizing and reducing bacterium), sulfate reducing bacterium (causes pit corrosion), and acid producing bacterium (causes pit corrosion). The testing takes just a few minutes. The results will appear over a period of up to 9 days to allow for bacteria culture growth.
