ASTM D92 Fully Automatic Flash Point Analyzer (Open-Cup)TPO-3000A

Application Standard

This instrument is designed and manufactured in accordance with the requirements stipulated in GB/T 3536-2008 Standard of the People's Republic of China "Determination of Flash Point and Flame Point of Petroleum Products Cleveland Open Cup Method" and ASTM D92. It is suitable for the determination of Flash Point of Petroleum Products whose Flash Point of Open Cup is higher than 79°C except fuel oil by the method prescribed in this standard.

Features

1. Control mode: Microcomputer control, automatic correction of system deviation, automatic correction of atmospheric pressure, and calculation of correction value.

2. Automation: automatic lifting, automatic sweeping and automatic detection.

3. The experimental procedures: according to the standard, heating rate automatically controlled, testing accurately, accurate, adopting new heating material, safe and reliable, and long service life

4. The experimental data are saved automatically and the instrument has the function of fault self-diagnosis.

5. High-precision ionization ring detection mode, automatic stopping while over heating.

Technical Paramters

1. Temperature Measurement Range: Room Temperature to 400°C

2. Accuracy: 0.1°C

3. Resolution: 0.1°C

4. Heating rate: At the beginning of heating, the heating rate of the sample ranges from 4(°C/min)~17(°C/min) .When the sample reaches the last 23°C±5°C before the expected flash point,the heating rate ranges from 5(°C/min)~6(°C/min)。

5. Test ignition source: natural gas, liquefied petroleum gas or butane gas/electronic ignition.

6. Ignition test cycle:  23°C±5°C before reaching the expected flash point, it will sweep once when the temperature increase very 2°C.

7. Flash point value: If the difference between the observed flash point and the initial ignition temperature is less than 18°C, then the result is invalid. In this condition,new specimens should be replaced and re-determined, and the initial ignition temperature should be adjusted until the effective results are achieved. That means the flash point value should be higher than the initial ignition temperature by more than 18°C.

8. Repeatability of measurements: Repeatability ≤4°C

Operating environment: (ambient temperature) 5~50°C. (Relative humidity) less than 80% RH

9. Power supply: AC230V±10%,50±1Hz

10. Power: 500W
