APPARATUS FOR MONITORING CORROSIVITY OF LIQUID |
摘要 |
A sensor is adapted to be mounted so that it comes in contact with coolant fluid of a vehicular cooling system. When the corrosion inhibiting characteristic of the fluid is effective to prevent corrosion a first potential range is produced whereas when the characteristic is ineffective a second range exists. The effectiveness of the inhibiting characteristic can be displayed in the form of a high impedance voltmeter mounted in the dashboard or other convenient location or indicating means such as a light can be actuated when the potential reaches a threshold level indicating that the inhibiting characteristic is not effective to prevent corrosion. The sensor comprises a reference electrode used with a single sensor electrode on one embodiment and with a pair of sensor electrodes in a second embodiment. |
