Overview
ZIBO KS-1 Open Cup Flash Point Tester conforms to GB/T3536, GB/T267, ASTMD92 standards. It is suitable for measuring the flash point and burning point of petroleum products, but it is not suitable for measuring petroleum products with the opening flash point of fuel oil below 79 ° C. The instrument adopts a solid state voltage regulator and controls the heater voltage by adjusting the knob to achieve the heating speed required by the standard.
Features
1. Adopt pure copper oil cup, which is resistant to burning and corrosion.
2. Adopt solid-state voltage regulator to adjust the pressure, and the heating rate is continuously adjustable without polarity.
3. Use electric heating tube to prevent direct contact between air and furnace wire and avoid oxidation of furnace wire.
Principle
The instrument regulates the input voltage of the heater through the solid state voltage regulator, thereby controlling the heating power, so that the sample in the oil cup heats up uniformly at the rate specified by the standard. During the heating process, the flash of the sample vapor and air mixture is regularly tested by a specific ignition device to determine its flash point and ignition point.
Applications
Determination of flash point and ignition point of petroleum products
Standards
GB/T3536、GB/T267、ASTMD92
Steps
1. Prepare the sample and fill it into a pure copper oil cup.
2. Connect the power supply and turn on the instrument.
3. Set and control the heating rate by adjusting the knob.
4. According to the method specified in the standard, the ignition test is carried out regularly during the heating process.
5. Observe and record the temperature when the flash fire occurs, which is the flash point.
6. If you need to measure the burning point, continue to heat and test, and record the temperature during continuous combustion.
Notice
• This instrument is not suitable for measuring petroleum products with an open flash point of fuel oil below 79 ° C.
Before operation, ensure that the instrument is properly grounded and comply with electrical safety regulations.
• Use a pure copper oil cup to avoid using Miscellaneous materials that affect test results or damage the instrument.
• Smooth operation is required when adjusting the heating rate to ensure compliance with standard requirements.
• There is an open flame during the test, and it is necessary to operate in a well-ventilated environment without flammable and explosive materials, and take good fire prevention measures.
• The working power of the instrument is 1KW, please pay attention to the electrical load.
• Clean the oil cup and instruments in time after use to keep the equipment clean.
