NAPPT-101 is an automated laboratory instrument that determines the lowest temperature at which petroleum products, oils, and lubricants remain flowable under controlled cooling conditions.
Automatic Pour Point Tester NAPPT-101 measures the lowest temperature at which fluids stop flowing by cooling the sample and detecting flow cessation using automated optical or pressure-based sensors.
Determines pour point of oils, fuels, and lubricants
Supports ASTM and ISO test methods
Automated cooling and detection system
Extended temperature range down to ~-80°C
Ensures repeatable and accurate results
Used in petroleum, chemical, and QC laboratories
The system is used to:
Measure low-temperature flow properties of petroleum products
Evaluate lubricant performance in cold environments
Ensure compliance with standardized testing methods
Support quality control and product development
Analyze fluid behavior under controlled cooling
The fluid sample is placed into the testing chamber.
The system cools the sample using a programmed temperature profile.
Sensors continuously monitor the sample for movement.
The system detects when the fluid stops flowing.
The temperature is recorded as the pour point and displayed.
Fluids become viscous or stop flowing at low temperatures.
NAPPT-101 determines the exact temperature where flow stops.
Prevents equipment failure in cold conditions
Ensures product stability
Supports compliance with ASTM/ISO standards
