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.

SENCOM™ SMART Digital Sensors
Yokogawa’s SENCOM SMART Sensor Platform is an innovative analyzer platform that optimizes maintenance, reduces configuration time, and simplifies in-field maintenance and calibration.
pH and ORP Analyzers
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 and ORP Sensors
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.
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.

Various installation options including retractable, flow thru, immersion, and direct insertion. Proper electrode/sensor selection is critical for optimal measurement results.
Dissolved Oxygen Analyzers
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 Sensors
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.
Yokogawa's Turbidity analyzers have been providing reliable turbidity measurement in Water Treatment Plants since 1959. The TB820D and TB830D are next-generation digital Turbidity analyzers that connect to FLXA402T. These are equipped with LED and new diagnostic functions, etc. to significantly reduce maintenance time.
You can find the best solution to meet the application needs, a non-reagent type chlorine analyzer for measuring free chlorine and a reagent type chlorine analyzer for measuring free chlorine or residual chlorine (total chlorine) are available.
Liquid Density Analyzer
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.
Fourier Transform Near-Infrared Analyzer (FTNIR)
An FTNIR allows for a real-time continuous measurement of multiple component concentrations in a variety of processes.
Wet Chemistry Analyzers
Yokogawa's wet chemistry analyzers are reliable and used for water analysis of sodium, silica, hydrazine and phosphate, so operators can minimize the increased risk of corrosion and associated component failure It can be reduced and mitigated.
Water Supply Treatment
FAST/TOOLS, STARDOM, Flowmeters, Liquid Analyzers
- Bali's water treatment plant decided to employ the latest reliable control system in order to increase availability and quality of operation.
- Centralized control system using FAST/TOOLS provides the sophisticated and flexible operation.
Problems at the wet end of a paper machine can rarely be corrected down stream. That is why monitoring and controlling pH in pulp stock is critical to the paper making process. Essentially, at every stage in the manufacture of paper, correct pH values play a vital role. Variations in the pH value at the head box have a negative effect on the quality of the paper produced.
After extraction from sugar cane or sugar beets, juice must be purified to remove the many other organics and minerals that accompany it. The processing to accomplish this is heavily dependent on reliable pH measurement and control as illustrated.
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.
