Fully automatic bench top centrifuge designed expressly for petroleum testing applications. Features a 4-1/2” LCD touch screen control panel. This integrated touch screen can be used to turn the heat on and off, set the duration of the test, set the RCF/RPM values and choose the type of rotor assembly and corresponding glassware to be used during the test.

The Koehler Air Release Value Apparatus consists of a test vessel and air flow control equipment for delivering heated air at the specified flow rate to a lubricating oil sample maintained at constant temperature. 

The carbon residue test serves as an approximation of the tendency of the test material to form carbonaceous deposits. The test material is subjected to evaporation and pyrolysis under certain conditions and the residue is weighed and the mass percentage calculated.

Dropping point determinations are used for identification and quality control purposes, and can be an indication of the highest temperature of utility for some applications. The sample is heated at a prescribed rate in a precision machined cup whose sides slope toward an opening at its center. The temperature at which a liquid drop first falls from the cup is the dropping point of the sample.

Cloud point and pour point are indicators of the lowest temperature of utility for petroleum products. The sample is periodically examined while it is being cooled in the cloud and pour point apparatus.

The Air Jet Erosion Test Rig has been developed to evaluate the erosion resistance of variety of materials and conforms to the specifications of ASTM G76 standard. The principle of operation consists of subjecting the test sample to a jet of air carrying the erodent, through a tungsten carbide nozzle of a known diameter. The impingement of the erodent particles on the test sample surface causes erosion and this is quantified by weight loss method. The particle velocity is controlled by varying the flow rate of air and the erodent feed rate is varied by changing the speed of the conveyor system which delivers the erodent to the jet of air. The particle velocity is measured with a well-established Double Disc arrangement method. The test sample temperature can be varied from ambient to 4000C and test sample inclination is infinitely variable 0-900 with respect to the jet of erodent particles.

Koehler’s Four Ball Tester determines the Wear Preventative (WP) and Extreme Pressure (EP) characteristics of lubricating oils and greases in sliding steel-on-steel applications. The test consists of rotating a steel ball under load against three stationary steel balls coated with lubricant.

Data Acquisition System incorporates sensor and signals with a combination of data acquisition hardware and software to create a complete measurement system. They measure Real Time Data of physical properties of test materials.
