17.5-Gallon Water Bath, Stainless Steel

The 17.5-Gallon Stainless Steel Water Bath provides circulating, digitally controlled temperature conditioning for Marshall asphalt specimens and other compatible materials-testing applications. Its stainless-steel tank, hinged cover and adjustable circulation help laboratories maintain consistent specimen temperatures before testing.

Key Features

• Used for specimen conditioning in workflows associated with AASHTO T 245, ASTM D6927, ASTM D5581 and AASHTO T 283, where applicable
• 17.5gal bath capacity
• Temperature capability up to 212°F (100°C), as listed by HMA
• Digital temperature controller with Type J thermocouple
• Temperature display selectable in °F or °C
• Variable-speed magnetic stirring for even bath temperature
• Gas-assisted hinged lid allows condensate to drain back into tank
• Perforated shelf keeps specimens 2 inches above tank bottom
• External drain valve
• Field-replaceable heating element
• Capacity listed by HMA: nine 6-inch TSR specimens or sixteen 4-inch Marshall specimens
• 115V, 12–15A electrical supply

Lab Manager's Tip

Provide a dedicated circuit suitable for the listed 12–15A load, and check water depth, circulation and temperature uniformity with a calibrated thermometer. For ASTM D6927/AASHTO T 245 Marshall work or AASHTO T 283 moisture conditioning, set the bath to the particular method's required temperature and duration—these procedures do not all use the same conditioning schedule.

Typical Applications

Marshall stability specimen conditioning, asphalt moisture-susceptibility conditioning, tensile-strength-ratio testing, asphalt mixture research and DOT asphalt QC laboratories.
