Built-in intelligenceDigital ISM pH and oxygen sensors feature an on-board microproces-sor. This allows a number of bene-fits that analog sensors cannot match, including predictive diag-nostics, sensor calibration in a safe environment, and a signal that is immune to interference.

Calibrate in the workshopWith ISM, buffer solutions do not have to be taken to the measure-ment point for pH sensor calibra-tion. Instead, using iSense™ soft-ware and a PC or laptop, sensors can be calibrated conveniently in a maintenance workshop then stored until they are required. When a sensor needs replaced, ISM’s Plug and Measure feature means the procedure takes only a minute.

Increase process reliability with predictive diagnosticsBeing able to predict when a pH sensor needs replaced and there-fore prevent a failing sensor from being used, would significantly im-prove process reliability. This is precisely the function of ISM’s Dy-namic Lifetime Indicator (DLI): By constantly monitoring process con-ditions and sensor “health”, the DLI provides a clear indication of a pH sensor’s remaining reliable operat-ing life.

Efficient maintenanceMeasurement point maintenance is usually based on a planned sched-ule. On the one hand this means maintenance is often conducted when there is no need for it, and on the other sometimes happens after a sensor has already failed. The in-formation from ISM’s predictive di-agnostics mean maintenance can be scheduled for when it is actually needed, saving time and costs.

Highly reliable pH measurement in reactorsIn various synthesis steps, whether organic or inorganic, pH is often a critical process parameter. METTLER TOLEDO pH electrodes are designed to provide dependable measurement performance across the widest range of process conditions. A clean sensor means good measurementDuring many processes, a drop in analytical parameter measurement accuracy is not due to a fault with the sensor; it is simply that the sen-sor is not clean. METTLER TOLEDO automated cleaning systems keep sensors in top condition, prolong sensor lifetime, and reduce operat-ing costs.

Low maintenance conductivity sensors for chemical concentra-tion controlGetting the desired concentration of acids, bases, and salt dilutions is fast and easy with conductivity measurements. Our conductivity sensors perform reliably in all these applications with little or no maintenance.

More efficient crystallization through turbidity measurementTo improve product purity and re-duce filtration and washing cycle time, crystal growth rate from start to end can be controlled efficiently with METTLER TOLEDO’s durable tur-bidity meters.

Turbidity sensors detect how much light is scattered by particles in the

process liquid.

In solid / liquid separation, deteriorating filter media or overfilled centrifuges lead to out-of-spec product. Also, in decantation processes in liquid / liquid separation, contamination or product loss easily occurs due to sluggish detec-tion of the interface layer. Turbidity and conductivity sensors can quickly detect filtration and phase separation issues, allowing rapid corrective action.

Greater efficiency in filtration processesBreakthrough of filter media can be detected at an early stage with METTLER TOLEDO in-line turbidity sensors. These enable operators to take rapid corrective action, ensur-ing that the quality of the filtrate is kept within specifications.

Higher yield in centrifuge operationsThe solid particle content in clari-fied liquids depends largely on the flow of the feedstock. Using turbid-ity values to control the flow is highly effective and greatly in-creases process yield. Our turbidity sensors have been designed to provide dependable, worry-free operation.

Storage, loading, and offloading of flammable liquids always carries the risk of fire and explosion when oxygen is present. In addition, products and chemicals can deteriorate in the presence of oxygen. Elimination of oxygen and air is therefore of great importance and needs to be care-fully monitored and controlled.

Safer vapor recovery and flare gas processesIn flares and in the recovery of va-pors of fuels and organic solvents from storage and process vessels, ingress of air is potentially very dangerous and needs to be kept below critical levels. This usually involves diluting the gas mixture with an inert gas. METTLER TOLEDO tunable diode laser oxygen sensors provide highly reliable in situ oxygen measurement that helps to ensure oxygen levels are within safe limits at all times. Cost-efficient nitrogen blanketingTo prevent flammable mixtures forming and to maintain product quality, vessel headspaces are typ-ically flooded with nitrogen. Con-trolling the nitrogen feed based on the oxygen concentration in a ves-sel not only increases safety but can also substantially reduce nitro-gen consumption. Amperometric oxygen sensors can be installed di-rectly in the vessel and are easy to maintain.

In situ sensors mean no measure-ment delayAll METTLER TOLEDO oxygen sen-sors are installed in situ and require no sample extraction or conditioning systems. This greatly improves safety as the number of components that potentially can fail are reduced to a minimum. A fur-

ther benefit is real-time analysis: Whereas conventional extractive analyzers suffer from measurement time lag, METTLER TOLEDO’s in situ technology provides accurate, real-time measurements allowing you to take action before problems develop.

Keep reverse osmosis systems at peak efficiencyRO system operations demand continuous monitoring of analytical parameters to detect and correct abnormal operating conditions and prevent damage to costly membranes.

Our instrument platforms include measurements of pH andORP. The same platforms measure conductivity and temperature for close surveillance of RO systemperformance. METTLER TOLEDO so-lutions help ensure RO systems are operating efficiently at all times.

Accurate pH measurement, even in demi waterEfficient operation and regeneration of ion exchangers also depends on continuous monitoring of key pa-rameters. Due to the lack of con-ductivity of demineralized water, measuring pH poses one of the biggest challenges to analyzer technicians. METTLER TOLEDO’s range of pHure Sensor® pH sys-tems ensures stable and accurate measurement at all times.

er Stay Ahead of Corrosion and Scaling Maintaining Heat Transfer Efficiency

Stop corrosion and deposition with pH and conductivity measurementsTo prevent corrosion and scaling in cooling water systems, pH needs to be controlled in a narrow range. In order to minimize mineral build-up, cooling water blowdown is initiated when the total dissolved solids (TDS) concentration reaches an upper level.

METTLER TOLEDO pH electrodes and conductivity instruments pro-vide dependable performance for pH and TDS measurement.

Rapid detection of heat exchanger leakage If process media leak into the cool-ing water system, ionic contamina-tion is normally detected through increased conductivity, or a change in pH or oxidation reduction poten-tial (ORP). In hydrocarbon indus-tries, when process fluids are organic and non-conducting, an excellent way of detecting hydro-carbons in cooling water is by measuring turbidity.

Easy disinfection controlBoth the temperatures and high oxygen levels in cooling water sys-tems provide excellent growth con-ditions for all kinds of biological foulants. Measuring the ORP is the most efficient way to control disin-fection with oxidants such as chlo-rine or hypochlorite.

And Lower Chemical Consumption

Reduced corrosion and scalingTo increase effectiveness, the strength of the scrubbing solution must be continuously measured and controlled. Lack of control carries risks of pollutants being released to atmosphere and corrosion of plant equipment. In addition, scaling of the scrubber vessel and plugging of pipes caused by a build-up of by-products reduces efficiency further, and inevitably leads to expensive maintenance.

Precise monitoring of scrubbing solution improves effectivenessIn batch scrubbers, the scrubbing solution depletes and will at some point lose its ability to absorb pol-lutants. A conductivity measure-ment can detect this lower limit and initiate blowdown or increase the bleeding of spent solution and ad-dition of fresh solution.

Benefits of pH / ORP control in continuous scrubberspH measurement is widely used in continuous scrubbers. With accu-rate control of the pH value, the scrubbing potency of the solution is optimized and scaling or corrosion problems can be avoided. Oxida-tion reduction potential (ORP) measurement can be used for monitoring a scrubber process when reducing or oxidizing agents are to be removed.
