pH sensor calibration procedure Instrumentation Tools

pH sensor calibration procedure Instrumentation Tools: A pH meter calibration is performed by measuring a series of reference standards, so-called pH buffers that have known and accurate pH values at different temperatures. Choose the appropriate buffered standards that will bracket the expected values at the sampling locations. If the water body’s pH is unknown, then three standards are needed for the calibration: one ...
