Gum formed during fuel storage can deposit on induction system surfaces, intake valves, stems and guides. To test for gum content, a 50mL sample is evaporated in an aluminum block bath for a specified period under controlled conditions of temperature and flow of air (aviation and motor gasolines) or steam (aircraft turbine fuel).

Features:

• Conforming to ASTM D381 and related specifications
• Choice of three-unit and six-unit models
• Safety top assembly allows for easy positioning and connection of all conical adapters to the bath
• Digital flowmeter for accurate and precise air flow measurement
• Available with built-in steam superheater
• Microprocessor programmable high accuracy temperature control
• Built-in pressure regulators and air flowmeters
