<p>Portable water test kit (1) comprising in unitary and modular form: means (5, 6) for testing a water sample to determine feacal coliform count thereof, means (10) for determining the turbidity of the said sample and means (9) capable of determining the residual chlorine level of the said sample. The novel use of unitary and modular form is vital in adapting the various tests to a single sample under an enormous variety of possible environmental conditions.</p> |
