Reliable sludge blanket measurement via optical sensor The sludge level meter OPTISYS SLM 2100 features an accurate and reliable profile measurement of the sedimentation tank using an optical sensor which travels through all layers of the tank reading suspended solids concentration at the different heights. — Optical measuring system for sedimentation profile measurement — Continuous level measurement of sludge blanket (zone tracking) — Common operating and service concept with other KROHNE devices

Engine dynamometers (engine test beds) with additional equipment for the thermal balance. Volumetric turbine-flowmeter for metering the air flow uptake at combustion engines. Volumetric turbine-flowmeter with electrical output and optical display for metering the heatflow in the radiator.

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The expert model OCA 200 is the contact angle measuring instrument for microscopic and macroscopic structures. Thanks to the 10x zoom lens and the autofocus system, the OCA 200 is suitable for any sample size from the macroscopic silicon wafer to the microscopic metal struts of a coronary stent. Together with the PDDS picolitre dosing system, the OCA 200 allows the analysis of droplets with a minimum volume of up to 30 picolitres. Measurements: - static contact angle - dynamic contact angle - interfacial and surface tension - surface energy - viscoelastic modulus - work of adhesion

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The premium model OCA 50 is a fully automatic contact angle meter. It is suited perfectly to investigate the wettability of solid surfaces and determine their surface energy. Complete measurement sequences from dosing and sample positioning to parameter analysis can be programmed according to the operator’s own specifications. The measurement sequences can be played repeatedly without manual intervention and thus meet highest reliability standard for measurement results. A special variant of the device enables measurements even on large 12″ wafers. Measurements: - static contact angle - dynamic contact angle - interfacial and surface tension - surface energy - viscoelastic modulus - work of adhesion

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The special model OCA 25-PMC is based on the OCA 25 standard model. With its high-pressure measuring chamber, the special model OCA 25-PMC offers the possibility of carrying out measurements of interfacial tensions and contact angles under high-pressure of up to 750 bar and at temperatures between -30 °C and 200 °C. This makes the OCA 25-PMC the ideal solution to investigate, for example, the interfacial tension between a surfactant solution and crude oil in reservoir conditions. It is also possible to determine the contact angle, for example, between rock, oil, and surfactant solution.

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The entry-level model OCA 15EC enables basic methods of professional contact angle measurement and drop shape analysis. Thanks to the modular construction, even this entry-level model can be combined with many accessories, such as the TBU 100EC tilting unit. Possible Measurements: - static contact angle - dynamic contact angle - interfacial/surface tension - surface energy - viscoelastic modulus - work of adhesion

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The OCA 25 standard model is the all-purpose system for contact angle measurements and drop shape analysis. The high-performance camera makes it possible to measure contact angles even on adsorbent surfaces such as tissues or powders. Compared to the entry-level OCA 15, additional measurements at temperatures of up to 700 °C are possible. Further advantages are the more precise positioning of the sample table as well as the compatibility with many more dosing systems, which allow electronic dosing and droplet volumes down to a minimum of ten nanolitres.
