What problems should be paid attention to during the use of industrial pH meters? The following article will expand on this:
(1) When used in the container, use the submerged type. If the measured medium has adhesion or fouling characteristics, use the cleaning type. The flow-through type is used in the pipeline, and the flow rate should not be too high, so as not to wear the glass film and reduce the service life. When there is pressure in the pipe, the pressure flow type should be selected. The pressure must be within the range allowed by the instrument. For the occasions where the temperature changes greatly, a thermal resistance thermometer should be installed for temperature compensation, because the pH value at different temperatures is different from the measured value. The resulting potentials are different.
(2) There are four cleaning methods: ultrasonic cleaning, mechanical scrubbing, solution jet cleaning and air jet cleaning.
