The Colifast At-Line Monitor - CALM - is a fully automated stand-alone early warning at-line analyser for rapid and systematic quality monitoring of E. coli, total coliforms, thermotolerant coliforms, and P. aeruginosa in waters. The technology is timesaving, cost reducing, and environmental friendly. The applications of the CALM span from raw water, in-process water,  waste water, to environmental monitoring, and this instrument is widely used within municipal waterworks, sewage plants, and other areas.

Depending on the method chosen, CALM will present results directly in CFU/ml, Most Probable Number (MPN), and/or Presence/Absence. Tests for two different bacteria may be performed simultaneously. 

The CALM is equipped with user-friendly, advanced custom software, and with remote control/warning possibilities.

No laboratory facilities and minimal skills in microbiology are required to perform the analyses.   Pre-filled vials in disposable trays along with reagent bottles make field servicing fast and simple.  The CALM-system consists of a sampling and analysing unit, an incubator unit with a robot-arm for distribution of the samples  (up to 76 samples), and a lap-top PC with instrument software. The CALM is pre-programmed to automatically sample flowing water at any location on a schedule predetermined by the user, and subsequently automatically perform the sub-sampling required to provide the results. Analytical results are transmitted instantaneously to the operator or laboratory by analogue signalling and/or GSM data, telephone-line, or standard internet connections.
