collo rszNew radio wave-based analysis technology, developed by the Finnish high-tech company Collo, makes it possible to continuously monitor the state liquids – thick slurries, resins, adhesives, coatings, emulsions, or other fluids – in industrial processes, Collo says.

Collo’s technology is based on an electromagnetic resonator that emits a continuous radio frequency field into the liquid. The signal reacts to interferences caused by different components, chemicals and phases in the liquid. The analyzer immediately warns if the process is disturbed in any way so that the process can be adjusted according to the online data.

“Our sensors can be placed anywhere in the process to optimize for instance the use of raw materials and chemicals in the critical process steps,” says Matti Järveläinen, CEO and founder of Collo. “Our analyzer monitors the process constantly, compared to manual samples that provide a delayed snapshot of the process status at a given time. The advantage of realtime monitoring is that it takes away the guesswork when adjusting the process, which in turn can save a lot of chemicals, materials, energy and time.”

The Collo Analyzer simultaneously measures eight proprietary parameters from a liquid, which together form the liquid’s fingerprint. If these characteristics are changed during processing, for example if unwanted solids are formed or the chemical balance is negatively impacted, the analyzer shows the changes so that corrective measures can be made immediately.

Unlike generic measurement techniques, Collo doesn’t just measure the liquids, but combines data with sophisticated analytics, providing actionable information for improved process performance. Analytics are adjusted for each liquid application for optimal results, the company says.

“The benefit of this continuous quality control is that process deviations are identified immediately when they occur and before they have caused any issues in the process or decreased its performance,” says Mikko Tielinen, Head of Sales. “If the problem is realized too late, it may escalate and become much more expensive to solve.”

Feature Video: DeVilbiss TEKNA Gun Flexes on Muscle Car Show

CFCM TeknaGun 400

Carlisle Fluid Technologies’ DeVilbiss TEKNA spray gun was recently featured on an episode of Detroit Muscle on Power Nation TV to bring a 1973 AMC Javelin back to life. Featuring a high finish quality and operator ergonomics, The TEKNA gun’s high transfer efficiency provides materials savings for solvent or waterbase paints.

The spray gun technology, which has been used in automotive refinishing processes for many years, is designed to spray all types of materials and comes with high efficiency or HVLP air caps that produce large spray patterns with even material distribution.

New Bacharach Sling Psychrometer


CFCM slingpsychrometer 400Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.

As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.

The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart. Gardco.com
