Lawler offers a wide range of constant temperature test baths conforming to ASTM D130, D1838, D4048, D4814 Annex, IP227, and ISO 2160 copper corrosion tests for fuel and lubricants. Specify which test method(s) are desired for proper model selection. Pressure vessels are used for more volatile products like gasoline and aviation fuels versus the test tube procedure used for lubricants, diesel, and biodiesel.

Model 279-8 is a stainless steel liquid bath able to accept 8 test bombs and 8 test tubes for the D130 test method. Alternate test racks are available.

The temperature range of Model 279-8 is 40° to +115°C, optionally to 190°C, with temperature stability of ±0.2°C. Temperature is controlled with a digital display controller with 0.1°C resolution. A float switch interrupts power to the bath in the event of low bath fluid level.

The bath is mechanically agitated to insure test point to test point uniformity. A cover over the bath is provided to reduce evaporation (if water is used as a bath medium).

Model 279-12 is identical to Model 279-8 except it is larger and able to accept 12 test bombs 6 test tubes. Alternate racks are available.

Lawler copper corrosion baths are also suitable for the silver corrosion test method that is part of the ASTM D4814 gasoline specification.
