ABSTRACT:
A method and apparatus for classifying fire fighting foam is disclosed. Fire fighting foam analyzer 10 uses a large capacity container 11 having a viewing window 12 disposed in a substantially vertical wall 13. The viewing window 12 has thereon a volume scale 14 containing volume graduations and a ratio scale 15. To classify a foam by a foam type, fire fighting foam analyzer 10 is filled with an initial volume of foam, the initial volume is recorded, solution is allowed to separate from the foam for a given period of time, a final solution volume is recorded, the ratio of initial foam volume to final solution volume is determined and the ratio is correlated to a particular foam type by reading the ratio scale 15.
