The ability of a lubricating oil to separate from water and resist emulsification is an important performance characteristic for applications involving water contamination and turbulence. Water separability is determined by stirring equal volume of water and sample together at a controlled temperature to form an emulsion and observing the time required for separation of the emulsion to occur. This method is suitable for petroleum oils and synthetic fluids. Rectangular model having double walled construction with toughened glass observation window ( 230 W x 200H mm). Illumination from rear side. 4 place Herschel Emulsifier. Added advantage of the stirrer being easily moved to each test position instead of moving the samples. Digital temperature, speed and timer. Timer stops the stirrer after 5 minutes automatically and audible alarm.

 

Features:

• Robust construction
• Easy to install
• Low maintenance

Copper Corrosion Bath Machine as per ASTM 130, IP 154, FTM 791-5225, DIN EN ISO 2160 / IP 227. The copper strip tarnish test assesses the relative degree of corrosivity of petroleum products, including aviation fuels, automotive gasoline, natural gasoline, solvents, kerosene, diesel fuel, distillate fuel oil, lubricating oil and other products. A polished copper strip is immersed in 30ml of sample at elevated temperature. After the test period, the strip is examined for evidence of corrosion and a classification number from 1-4 is assigned based on a comparison with the ASTM copper strip corrosion standards.

 

Features:

• For aviation fuels and natural gasoline the sample tube is placed inside a stainless steel bomb during testing.

• 6 place constant temperature bath.

• Lid with hook to lay low-pressure bombs.

• Stirring device for excellent temperature uniformity.

• Digital temperature controller with PT-100 sensor.
