Automatic Pour Point Tester NAPPT-100 – Low-Temperature Flow Analysis Equipment

What is an Automatic Pour Point Tester NAPPT-100?

NAPPT-100 is an automated laboratory instrument that determines the lowest temperature at which petroleum products, oils, and lubricants remain flowable under controlled cooling conditions.

Quick Answer 

Automatic Pour Point Tester NAPPT-100 measures the lowest temperature at which oils, fuels, and lubricants stop flowing by cooling the sample and detecting flow cessation using automated sensors.

Key Takeaways

• Determines pour point of oils and fuels

• Supports ASTM and ISO standards

• Automated cooling and detection system

• Temperature range down to ~-70°C

• Ensures consistent and repeatable results

• Used in petroleum and QC laboratories

What Is NAPPT-100 Used For?

The system is used to:

• Measure low-temperature flow properties of petroleum products

• Evaluate lubricant performance in cold environments

• Ensure compliance with testing standards

• Support quality control and product specification

• Analyze fluid behavior under controlled cooling

How Does NAPPT-100 Work? (Step-by-Step)

Step 1: Sample Loading

The fluid sample is placed into the test chamber.

Step 2: Controlled Cooling

The instrument cools the sample using a programmed temperature profile.

Step 3: Flow Detection

Sensors monitor the sample to detect when flow stops.

Step 4: Pour Point Determination

The temperature at which flow ceases is recorded.

Step 5: Result Output

Final results are displayed and stored digitally.
