Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample.
Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.
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.
pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP.
Titration instruments are used to determine the concentration of dissolved substances. Titration is based on a complete chemical reaction between the specific substance, the analyte, and a reagent or titrant of known concentration that is added to the sample.
Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect the reading.
Water quality photometers and colorimeters are ion-specific, computer-interfaced probes that are designed to determine the concentration of a solution from its color intensity.
Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement.
