A well deserved reputation for ruggedness, longevity and accuracy hallmark the TB(X)5 series pH / redox sensors. The sensors are easily applied to most industrial measurement needs. They are renowned for their ability to outperform conventional sensors in the industries' toughest process applications. Solid-state Next Step™ reference technology is the foundation for all TB(X)5 Series electrodes. The totally solid inner reference chamber is charged with potassium chloride (KCl). This non-liquid reference all but eliminates poisoning, plugging and pumping problems that plague conventional liquid, slurry and gel designs.

The AW401 design enables connection of up to 3 residual chlorine monitoring sensors to the system or enables pH, ORP and residual chlorine sensors to be combined, thus reducing the cost of each measurement considerably.

• Total and free residual chlorine measurement – add potassium iodide to reagent to convert free chlorine measurement to total chlorine
• Reagentless operation – reduced operating costs with reagentless operation at a pH of 7.5 or less
• Multiple sensor input capability – reduced installation costs for multiple point monitoring operations
• Self-cleaning sensor assembly – prolongs sensor life and maintains accuracy

Product BrochureNatural organic matter (NOM) is a complex and heterogeneous mixture of organic substances produced from vegetative decay processes that create problems for water treatment plants tasked with producing drinking water of a consistent high quality. The majority of NOM originates from the soils. These aquatic humic substances are mainly derived from decomposing plants and animals and color the water from yellow to brown. It is important to remove humic substances prior to chlorination, as any remaining NOM will react with the added chlorine to create undesirable disinfection by-products (DBPs) such as trihalomethanes (THMs).

ABB offers two analytical methods for detecting organic matter in water: AV400 Series and Aztec 600 Color Analyzer.

• Single input, cost effective, low range instrument
• Reagentless operation reduces running costs and maintenance
• Automatic cleaning with programmable frequency to suit application
• THM (trihalomethanes) precursor alert provides advanced warning of increased risk of THM development

ABB conductivity analyzers are designed to meet the most exacting requirements of our valued customers. The extensive range covers 2 and 4-wire analyzers and single or dual-input devices.

Our hazardous area certifications embrace FM, CSA and CENELEC ATEX intrinsic safety. Instruments are available with HART, Profibus PA or DP, and Foundation Fieldbus communications capabilities.

2-Electrode Contacting Cells - Range 0 to 10,000 µS/cm
High accuracy technique for trace conductivities from ultrapure water to industrial rinse waters. An alternating current is passed between two electrodes in contact with a solution. The transmitter converts the resultant potential difference into conductivity, concentration or specific resistance.

4-Electrode Contacting Cells - Range 0 to 2,000 mS/cm
Auto-compensating technology for high level conductivity and concentration measurements in high-coating processes. Provides an alarm when cleaning is required.

Electrodeless sensors - Range 0 to 2,000 mS/cm
Non-contact technique providing immunity to polarisation, oily fouling and non-conducting coatings until gross fouling occurs. Measurement of the magnitude of induced current into a closed loop of solution using two embedded toroids.

2-electrode, contacting, conductivity cells

Range 0 to 10,000 µS/cm (0 to 20,000 µS/cm using TB82TE analyzers)

High accuracy technique for trace conductivities from ultrapure water to industrial rinse waters. An alternating current is passed between two electrodes in contact with a solution. The transmitter converts the resultant potential difference into conductivity, concentration or specific resistance.
