Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control. Common measurements include pH, ORP, conductivity, resistivity, percent concentration and dissolved oxygen.
Liquid analysis is essential for protecting capital assets including boilers and cooling towers, by preventing corrosion, minimizing maintenance, and maximizing uptime.
Yokogawa is a recognized world leader for reliable liquid analytical equipment, providing accurate and repeatable solutions for maintaining and controlling even the most demanding process applications with unparalleled ease of operation.
pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications.
pH electrodes and sensors are the sensing portions of a pH measurement. Various installation options including retractable, flow thru, immersion, and direct insertion. Proper pH electrode/sensor selection is critical for optimal measurement results.
Digital or SMART sensors maintain specific measurement and calibration data on an integrated chip along that is an integral part of the sensor. This data can be exchanged between the sensor and either a process transmitter or a laboratory PC using a data management software, like the SPS24.
Conductivity meters, analyzers and transmitters are used for continuous process measurement and monitoring of conductivity, resistivity, WIFI, demineralizer water, RO water, percent concentration, boiler blowdown and TDS.
Conductivity sensors and electrodes are used to measure process conductivity, resistivity, WIFI, demineralizer water, RO water, percent concentration, boiler blowdown and TDS. Various installation options including retractable, flow thru, immersion, and direct insertion. Proper electrode/sensor selection is critical for optimal measurement results.
Dissolved Oxygen (DO) meters, analyzers and transmitters are used for continuous process measurement and monitoring of milligrams per liter (mg/l),parts per million (ppm), parts per billion (ppb), or % saturation.
Dissolved Oxygen (DO) electrodes and sensors are the sensing portions of a DO measurement. There are three common technologies for dissolved oxygen measurements: polographic, galvanic and optical. Various installation options including floating ball, retractable, flow thru, immersion, and direct insertion.
The lineup of turbidity analyzers including the TB750G right angle scattered light turbidity analyzer, and the TB400G surface scattering light turbidity analyzer for the measurement of turbidity in water.
Chlorination is employed in most water treatment processes to remove metallic ions and biological contaminants, and to suppress subsequent growth of bacteria and other biota.
The RC400G / the FC400G residual and free chlorine analyzers are high performance and accuracy systems with a microprocessor incorporated and are mainly used for the measurement of residual and free chlorine in water.
The SS400 MLSS Analyzer is a measuring system best suited to continuously and consistently measure the concentration of mixed liquor suspended solids (MLSS) in an activated-sludge treatment process found in sewage or industrial wastewater treatment facilities.
The DM8 liquid density analyzer measures liquid density of general process liquids with high sensitivity and excellent stability. It has a measuring density range of 0 to 2.0 g/cm3, and unaffected by flow rate and viscosity. Besides general-purpose sensor, sanitary and explosionproof sensor are also available.
An FTNIR allows for a real-time continuous measurement of multiple component concentrations in a variety of processes.
The sensor wiring guide incorporates Yokogawa designed and supported sensors and analyzers across the entire liquid measurement product line.

To facilitate the accurate measurement of pH, and its presentation as a scale, a range of "standard liquids" or "buffer solutions" are used. These liquids, whose constituents are accurately defined, have known stable values. Although in the preceding text the relationship to hydrogen ions has been made, research has shown, that the activity of hydroxonium ions (H30+) is more relevant.
