A wide classification of sensors that are used to analyze material samples, or their components, and record data specific to the application.
Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample.
Conductivity electrodes are devices that measure the salinity and conductivity of water samples.
Dissolved CO2 instruments are analytical devices that measure the amount of carbon dioxide (CO2) dissolved in a liquid sample such as water. They typically include a submerged probe that is covered by a thin organic membrane.
Dissolved oxygen meters are analytical instruments that are used to measure the amount of oxygen dissolved in a liquid sample.
Dissolved oxygen sensors are used to measure the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and wastewater treatment, the amount of dissolved oxygen (DO) must be kept high.
Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements.
Ion selective electrodes measure the potential of a specific ion in solution. This potential is measured against a stable reference electrode of constant potential.
Ion specific electrode meters are millivolt meters that interface with ion selective electrodes (ISEs). These meters take the potential generated by the electrode and convert it into units of concentration.
Oxygen reduction potential (ORP) electrodes are analytical sensors for measuring oxidation-reduction potential (ORP).
Oxidation reduction potential (ORP) instruments measure or monitor ORP in solution.
pH electrodes are analytical sensors for measuring potential of hydrogen (pH), the negative logarithm of the hydrogen ion activity in solution.
pH instruments are used to measure or monitor potential of hydrogen (pH) in a solution.
Smoke detectors are designed to sense the products of combustion. Common types include ionization chambers and photoelectric devices.
