K25330 Copper Strip Tarnish Test Apparatus

Test Method
The Copper Strip Tarnish Test assesses the relative degree of corrosivity of petroleum products, including lubricating oils. 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 and Benefits
• Conforms to ASTM D130, D6074, D6158 and related specifications
• Accommodates 16 test tubes
• Temperature range to 190°C (374°F)
• Microprocessor temperature control with digital display and overtemperature protection.

K25330 Copper Strip Tarnish Test Apparatus
Constant temperature bath immerses 16 test tubes for copper strip tarnish tests of products not requiring a test bomb. Microprocessor temperature control 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 double-wall construction with built-in support rack. Fully insulated.
