Koehler Copper Corrosion Test Bath System

Microprocessor temperature controller for stability

Determine the corrosiveness to copper of petroleum-based fuels and biodiesel by immersing a copper strip in the test sample at an elevated temperature. Compare the tarnish color of the strip to a ASTM Copper Strip Corrosion Standard (sold separately) to assess the relative corrosiveness level.
The constant-temperature bath features a digital temperature controller and a 750-watt heater; maintains a temperature stability of ±2°F (1°C). Overtemperature control interrupts power to the heater if programmed temperature is reached. Built-in support rack holds up to 16 test tubes.
