Pour point is an important indicator of the low-temperature fluidity of petroleum oils. It represents the lowest temperature at which an oil sample remains flowable under specified test conditions. This parameter is widely used to evaluate the suitability of transformer oils, lubricating oils, and light petroleum products operating in cold environments.

Our Automatic ASTM D97 Pour Point Analyzer adopts advanced microcontroller temperature control and cascade refrigeration technology to ensure stable and accurate low-temperature measurements. The system automatically monitors the cooling process and performs sample tilting detection to determine the pour point.

In many laboratories, pour point testing is often performed together with cloud point testing to evaluate the overall low-temperature performance of petroleum products.

The instrument is widely used in petroleum refineries, lubricant manufacturers, power utilities, testing laboratories, and research institutions.

The Automatic Pour Point Analyzer is suitable for testing low-temperature properties of:

• Transformer insulating oil
• Lubricating oils
• Light petroleum products
• Industrial oils

Typical application environments include:

• Petroleum refineries
• Lubricant manufacturing plants
• Power utilities and transformer maintenance laboratories
• Quality inspection laboratories
• Scientific research institutions

The system performs potentiometric titration using high-precision pH electrodes and advanced control algorithms to determine titration endpoints accurately in non-aqueous environments.

The graphical interface displays the testing process in real time, allowing operators to observe the working status of the instrument.

A microcontroller-based PID temperature control system ensures precise temperature regulation with an accuracy of ±0.1°C, providing stable and repeatable test conditions.

The system can heat samples up to 25°C and cool them down to –70°C, enabling testing of various light petroleum products under extreme low-temperature conditions.

During testing, the sample holder automatically tilts to 45° to determine the flow condition of the oil sample, ensuring compliance with standard pour point testing procedures. Both rapid detection mode and standard test mode are available.

The dual-stage cascade refrigeration system provides rapid cooling and stable low-temperature operation with long service life.

The instrument can store 300 test records, with optional storage expansion up to 500GB, allowing convenient data retrieval and laboratory data management.

The instrument includes a built-in diagnostic system that automatically detects operational errors and alerts the user to prevent measurement inaccuracies.
