Constant temperature water bath immerses twenty-one test cylinders for vapor pressure tests on liquid products and liquefied petroleum gas (LPG). Electronic level control automatically maintains the proper immersion depth per ASTM specifications. Heating system employs a 6kW stainless steel heat exchanger with a heavy duty circulating pump to provide rapid heat-up, even heat distribution and ease of servicing. Convenient digital set point and display permits rapid selection of any bath liquid temperature within the operating range. Temperature Range: 212°F (100°C). Temperature Control Stability: ¬±0.2°F (¬±0.1°C). A built-in over-temperature limit control protects against accidental overheating. Bath interior and internal components are constructed of heavy gauge stainless steel. A hinged acrylic cover shields control panel. Includes sturdy angle-iron base with corrosion resistant polyurethane finish. Order pressure gauges and cylinders separately. See P4091 for other required accessories. Conforms to the specifications of: ASTM D323, D1267; GPA 2140; IP 69, 161; ISO 3007, 4256; DIN 51616, 51754; FTM 791-1201.
