ZX-KSR Automatic Open Cup Flash Point and Fire Point Tester: Technical Overview

The ZX-KSR Automatic Open Cup Flash Point and Fire Point Test Apparatus is a precision instrument designed for the accurate and efficient determination of the flash point and fire point of petroleum products. This equipment is essential in ensuring safety and quality compliance across industries such as petroleum refining, power generation, chemical manufacturing, and inspection services. By automating the testing process, it enhances repeatability, minimizes human error, and improves laboratory productivity.

Core Functionality and Features

The apparatus performs simultaneous testing of both flash point and fire point in accordance with the ASTM D92 standard. Its open-cup design replicates real-world conditions where vapors can disperse, providing critical safety data for handling, storage, and transportation of flammable liquids.

A key feature is its advanced automation. The instrument conducts the entire test sequence autonomously—including temperature control, ignition application at precise intervals, detection of flash/fire point, and post-test forced-air cooling. This automation is managed via an intuitive color LCD interface, which also allows for real-time monitoring of the test progression and a real-time clock for data logging.

Technical Specifications and Performance

The ZX-KSR delivers high accuracy and reliability through robust technical design:

1.Measurement Range: 40°C to 450°C, covering a wide spectrum of petroleum products.

2.Temperature Control & Sensing: Utilizes a platinum resistance thermometer (PRT), ensuring high-precision temperature measurement with an accuracy of ±1°C and a resolution of 0.1°C.

3.Repeatability: Demonstrates excellent consistency, with a variation of ≤4°C for consecutive tests on the same sample.

4.Ignition and Detection: Employs reliable electric ignition. The system automatically detects the flash point (the lowest temperature at which vapors ignite) and the subsequent fire point (the temperature at which sustained combustion occurs).

5.Data Management: Capable of storing up to 500 complete test results internally. A built-in thermal printer provides immediate hardcopy reports for record-keeping.

6.Safety and Diagnostics: Incorporates a self-checking system for critical mechanical components like the lift bar and sliding bar, as well as the printer, ensuring operational integrity.

7.Cooling System: Integrated forced-air cooling rapidly reduces chamber temperature after testing, enabling faster sample turnover.

8.Power Requirements: Operates on AC 220V ±11V, 50Hz ±2.5Hz, with a power consumption of less than 600VA.

Operational Advantages for Technicians

For the technical user, the ZX-KSR offers significant operational benefits:

1.Effortless Workflow: The "auto-test, auto-cool, auto-prompt" functionality streamlines the testing process, allowing technicians to focus on other tasks.

2.Enhanced Data Integrity: Automated result capture and printing eliminate transcription errors. The substantial internal memory facilitates data traceability and analysis.

3.Reliable Compliance: Adherence to ASTM D92 ensures that results are recognized for quality control and specification purposes.

4.Robust Construction: With a net weight of 18 kg, the instrument is designed for stability and durability in a laboratory environment (operating within 10–35°C and <90% humidity).

Conclusion

The ZX-KSR Automatic Open Cup Tester represents a sophisticated integration of precise thermal control, automated ignition sequencing, and intelligent data handling. It provides technicians in petroleum, chemical, and related industries with a reliable, standards-compliant, and user-friendly solution for critical flammability safety testing. Its design emphasizes accuracy, repeatability, and operational efficiency, making it a valuable asset for any laboratory focused on material safety and specification analysis.
