When selecting the meter, consider:<\/p>\n<ul>\n<li>Cost<\/li>\n<li>Portability<\/li>\n<li>Battery operated or electric power<\/li>\n<li>Waterproof or nonwaterproof<\/li>\n<li>Temperature displayed or need to push a button to get temperature<\/li>\n<li>Data printing capabilities<\/li>\n<\/ul>\n<p>Also, when multiple measurements are required, it may be more convenient and cost-effective to purchase a multiparameter meter that can measure any combination of pH, conductivity, dissolved oxygen, temperature, salinity, turbidity, and more.<\/p>\n<p>Cup-style meters allow analysts to pour the solution directly into the meter rather than dipping an electrode in the sample. Cup-style meters generally require less sample and their cable-free sensors offer convenience.<\/p>\n<p>For continuous measurement of conductivity in process applications, such as in a water plant, chemical processing, or plating tanks, transmitters or controller\/transmitter combinations are an effective solution. Depending on the model, the transmitter can be wired to meet specific application needs.<\/p>\n<p>For simple water testing for hydroponics, pocket testers are an economical alternative to benchtop or handheld meters.<\/p>\n<p><strong>Keeping the Meter Calibrated<\/strong><\/p>\n<p>Most conductivity instruments today are microprocessor based and don\u2019t drift. However, small physical changes to the cell can change readings over time. For best results, verify performance with certified calibration standards at regular intervals. Typically, multifunction calibrators, standards-grade reference multimeters, and precision resistors (per the manufacturer\u2019s procedures) are used to calibrate conductivity and resistivity meters by a calibration service provider.<\/p>\n<p><em>View our selection of <\/em><a href=\"https:\/\/www.coleparmer.com\/Category\/Conductivity_Resistivity_TDS_Meters_and_Testers\/555?referred_id=5618\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><em>conductivity meters, testers<\/em><\/a><em> and <\/em><a href=\"https:\/\/www.coleparmer.com\/Category\/Conductivity_Electrodes_Industrial\/56927\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><em>electrodes and sensors<\/em><\/a><em>.
