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 

NAPPT-100 Automatic Pour Point Tester 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.
