We here at M4 Knick love three things: being in love, having a good laugh, and analytical instrumentation of course. So, we’ve got you covered this Valentine’s Day. We created a list of 10 swoon-worthy pickup lines and memes to impress your next date— liquid analysis style.
Ok, Ok, it’s a little low-brow, but hey the analytical equipment industry is rampant with terminology just waiting to be a turned into pickup lines. Seriously, who can resist a good pH probe joke?! We sure can’t.
Sour water is a byproduct from steam stripping of crude oil in a variety of refinery distillation processes. Sour water treatment removes ammonia and hydrogen sulfide from water, both are damaging to overhead condensers and other process piping and vessels. The flash drum removes light hydrocarbons from the sour water before the water moves... Continue reading

Check out the predictions these liquid analytics professionals have provided regarding the impact digital sensing technology will have on predictive maintenance, asset management, product quality, reporting and safety in 2019.
A common question I get from customers about pH measurement is "How accurate is my sensor?". You'd think there would be a straightforward reply like 0.25% of range or 0.5 pH of the span. Unfortunately, it's difficult to provide a definitive answer to this question. As a matter of fact, it's rare to see an accuracy specification for most process pH electrodes. When you do see one, there are a number of exceptions. This is because there are many uncertainties and potential measuring errors, such as:Buffer solution degradation or contaminat...

This corrosion resistant sensor is constructed of PEEK in a smooth, easy-to-clean design and comes with an integrated 3m cable. The SE 655 is highly accurate and has a low risk of contamination because of a large sensor opening.
The robust sensor design and construction, along with t... Continue reading
The bleaching process is very challenging for pH electrodes due to plugging and chemical attack. The pulp consistency can easily reach 10% and quickly plug the junction of the many pH electrodes. The pH range of the pulp changes drastically several times during bleaching. This alternating chemical process yields extreme pH values of around 3.5 in the chlorine dioxide (ClO2) stage and a value of around 11.5 during the c... Continue reading
The SE 554 Memosens pH sensor is ideal for use in liquids with suspended solids and high ionic strength. This low-maintenance sensor is constructed using Alpha pH glass, 2 open hole junctions & a solid polymer electrolyte with high KCl concentration. These features provide stable performance and long life in the most difficult applications.
The integrated NTC 30K temperature element assures that all pH measurements are accurat... Continue reading
Liquid analytical measurements in sugar refineries are challenging due to the processes needed to convert the sugar contained within the sugar beets into a concentrated liquid called thick juice.
Critical steps in the sugar purification process are 1st and 2nd carbonation. Continuous pH monitoring is needed to ensure the efficiency of the carbonation stage. Because of the potential for excess... Continue reading
Need a reliable pH measurement in boiler or RO water? As long as the conductivity of your measured medium is above 10µS/cm there is no reason to use a liquid-filled sensor. Gel-filled sensors provide a low-cost, low-maintenance alternative without compromising performance.Continue reading

Constructed using Alpha pH glass, 3 ceramic junctions, and a KCl reservoir, the SE 558 is a great alternative to high-maintenance, liquid filled pH sensors. An integrated NTC 30K temperature element assures that all pH measurements are accurately compensated for the temperature... Continue reading
The SE 555 Memosens pH sensor is ideal for use in a wide range of applications. The sensor is designed to withstand extreme pH ranges, aggressive media, and applications requiring frequent CIP or SIP cleaning. An integrated NTC 30K temperature element assures that all pH measurements are accurately compensated for the temperature of the process media. The pressurized reference system, along with the Silamid reference electrode, help to ext... Continue reading
pH is monitored at the filler in each packaging line, right before the product is bottled or canned. Downtime is unacceptable and costly.
Being the final quality assurance measurement, high precision is required. Any drift, delayed response, or inaccuracy must be immediately addressed through calibration or sensor replacement.
Typical contributors to unreliable sensor performance are:Moisture in the sen... Continue reading
The CL-90 electro-pneumatic cleaning system is a cost-effective tool that helps address pH, ORP, and dissolved oxygen sensor performance issues in processes containing suspended solids. When paired with the Stratos Evo transmitter and Sensogate WA 131 pneumatic retractable holder, the CL-90 provides a compact engineered solution for the automat... Continue reading
The slurry of a corn mash tank contains liquids and fine solids particles. The thick slurry can quickly plug the junction/diaphragm of a pH sensor causing it to drift. This often requires frequent maintenance to clean the junction and recalibrate the sensor. In some cases the sensor is just replaced with a new one. Removing a pH sensor by hand from the process can be dangerous due to high temperatures and pressures.... Continue reading

Remember when it was the screech under the hood or the burning oil smell that told you something was wrong with your car? What did we do before our cars told us it was time for service? We didn’t just get rid of our car and buy a new one, we brought it to the mechanic for evaluation and repair.
Today, we have clear diagnostics on our car’s dashboard that pinpoint the problem and indicate when it’s time for service. The same benefit is available with Memosens smart pH sensor te... Continue reading
