Koehler Copper Strip Corrosion from Lubricating Grease

** Please contact us for pricing & details. Online orders will not be accepted.

Measures the tendency of lubricating grease to corrode copper under static conditions. A polished copper strip is immersed in a sample of grease at elevated temperature for a specified period. The strip is examined for corrosion and a classification number from 1-4 is assigned based on a comparison with the ASTM Copper Strip Corrosion Standards.

Constant temperature bath immerses 16 test jars for lubricating greasesl. Microprocessor temperature controller has °C/°F switchable digital setpoint and display. Operator and equipment are protected by an overtemperature control circuit which automatically interrupts power to the unit should bath temperature exceed a programmed cut-off point. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. Welded stainless steel inner wall and powder coated steel outer wall construction with built-in support rack. Fully insulated.
