METHOD OF CONTROLLING THE AMOUNT OF SANITIZING AGENT IN AN AQUEOUS MEDIUM |
| 摘要 |
<p>A method where an aqueous medium is provided and its conductivity determined (38). A source of at least one conductivity increasing substance (26) is introduced controllably into the aqueous medium and a second conductivity measurement is made (42). The determined conductivities are compared and the amount of conductivity increasing substance is increased in response thereto.</p> |
