Automated online early-warning system for E. coli and coliforms: results in 6–15 hours, 21 days unattended.
Colifast ALARM draws a 100 mL sample from the supply line, mixes it with Colifast growth medium and tracks fluorescence to confirm bacterial activity. If a threshold is crossed it sends SMS alerts or triggers control-room alarms, and integrates fully with Liquid Science IoT.
