Reference sensors

The pH measurement is basically the measurement of differential electricity generated between two sensors/electrodes. This electric potential, expressed in mV, occurs due to the presence of ions H+ that are "absorbed" by the glass sensor in relation to the reference system. Once the pH measurement is highly disseminated and used throughout the world and in almost all sectors and chemical segments, it was agreed to use a single pH sensor, named Combined. This piece has on its single body, sensors of measuring and reference. However, some technical and elaborate procedures require the use of a reference sensor separate from the measuring sensor. For these cases choose the model or type of application. Importantly, the sensors reference only measure pH when used in conjunction with the SM01measuring sensor.
