A pump used to move and meter slurries, solutions, or food products that must be processed according to certain cleanliness standards required either by law or a company`s own regulations. They are designed to meet regulatory requirements usually have to undergo on-site inspections from representatives the Food and Drug Administration or the U.S. Department of Agriculture.
Sanitary pumps are available with a variety of features. Adjustable speed pumps can operate at speeds selected by an operator while continuous duty pumps maintain performance specifications at 100% duty cycle. Run dry capable pumps can operate without pumped fluid or external lubrication for an extended period of time. Some wastewater pumps include a backup battery, grinding mechanism, pressure gage, control panel, level control device, thermal overload protection, strainer, filter, or suction. Other wastewater pumps are belt-driven, close coupled, explosion-proof, frame mounted, hygienic, jacketed, sealless, self-priming, portable, or are configured to pump sticky or stringy materials. Multistage, reversible, plug-in, and washdown duty capable devices are also available. Sanitary pumps can move media either vertically or horizontally, depending on the direction of the pump stator/rotor assembly.
Sanitary pumps are used in a variety of commercial and industrial applications. Examples include agriculture and horticulture, brewery and distillery, dairy, food processing, food service, medical, municipal, OEM supply, and pharmaceutical and biotechnology applications.

Industrial in-line pH meters need to be re-adjusted after use for a period of time, depending on the solution being measured and the frequency of use. After a period of use, the electrodes of the industrial online pH meter are asymmetric and the potential will change greatly, so regular calibration is required.
The number of industrial on-line pH meter calibrations depends on the performance of the sample, the industrial on-line pH meter, and the accuracy of the measurement. High-precision measurement (≤ ± 0103 pH), should be promptly calibrated; General accuracy measurement (≤ ± 011pH), after a calibration can be used continuously for two weeks or more. As long as the measurement shows that the pH is accurate, there is no need to calibrate the ph electrode frequently.
First test the standard solution that is closer to the measured solution, and determine if recalibration is needed based on the error size. It must be recalibrated in the following cases:
1 Replace the new industrial online pH meter electrode.
2 Industrial On-line pH meter After measuring concentrated acid solution (pH<2), or after measuring concentrated alkali solution (pH>12).
3 Industrial Inline pH Meter After measuring a fluoride-containing solution or a concentrated organic solution.
4 When the temperature of the tested solution is too large compared to the standard solution temperature (or room temperature). 
Why Industrial In-Line pH Meters Are Calibrated Regularly
The accuracy and longevity of industrial on-line pH meters depends on the industrial on-line pH meter electrodes. The price difference is also very large, but many times it is used improperly, resulting in inaccurate measurements.
