Description
BAMOPHOX 319 ML-DB Bamo Resistivity Meter for process control and survey of demineralized water through two bottles of resins. Input 1: controls the first bottle, as a blind instrument (without display).
As soon as the fluid resistivity is less than the preset value relay 1 switches a signal alarm to inform the operator. Input 2: controls the second bottle with its own alarm parameters. The measurement of resistivity is permanently displayed. 3 relay outputs are to be used either for input 1 or input 2; adjustments are done by the operator. The 4-20 mA outputs allow the report of process operations, in order to have a true image of water quality.
