The two most recognized applications of the SBT^®+2 are the SBT^® test (ASTM D5133 & D7110) and the Low-Temperature Viscosity Test (ASTM D2983). The use of the patented SimAir^® Test Cell allows the SBT^®+2 to be held at a constant temperature during the 16-hour soak period of the D2983 test. This provides greater versatility, increased sample throughput, and improved precision over air baths and programmable liquid baths.

The versatility of the SBT^®+2 bath stems from its broad cooling range, both manual and automatic temperature control, the incorporation of a viewing window, and five easily replaceable bath covers (Insert Modules). The bath now serves as a cooling source for seven different low-temperature test methods — making it a cost-effective instrument for demanding lab schedules.

• Versatile liquid bath for analyzing lubricants and fluids meeting numerous low-temperature test methods.
• Easily replaceable Insert Module for each test.
• Programmable & Manual bath temperature controls.
• Self-contained refrigeration system capable of cooling to -70°C.
• Generates the Gelation Index & Gelation Index Temperature according to ASTM D5133 and D7110 methods.
• Designed for use with patented SimAir^® Test Cells for Low-Temperature Viscosity D2983 testing.
• Ideal for low-temperature work with fresh, sooted, or highly oxidized oils, ATFs, and fuels.
