I. Purpose and Scope of Application

HZHF-100 petroleum product ash analyzer is designed and manufactured in accordance with the requirements specified in the Chinese standard GB/T 508 "Determination of Ash Content in Petroleum Products", and is suitable for determining the ash content of petroleum products according to the method specified in GB/T508. However, this instrument is not suitable for the determination of ash content in petroleum products containing raw ash additives (including certain phosphorus containing compounds), lubricating oils containing lead, and used engine crankcase oils.

The summary of the ash content test method is to use ash free filter paper as the ignition core, ignite the sample placed in the crucible, and burn it until only ash content and residual carbon remain. The carbonaceous residue is then heated and converted into ash in a 775 ℃ high-temperature furnace, cooled, and weighed.

II. Performance Characteristics

1. The furnace adopts a ceramic fiber structure, which is light in weight, has low heat melting, and has low empty furnace losses, saving more than 70% energy.

2. The heating rate is fast. It only takes about 15-35 minutes to raise the room temperature to 1000 ℃.

3. Adopting intelligent P I. D instrument has functions such as self-tuning, temperature error correction, timing, and over temperature alarm. Easy to operate, precise, reliable, and safe temperature control.

4. Unique power-off function when opening the door. After the furnace door is opened, the equipment automatically disconnects the heating power supply to ensure the safety of the operator.

5. Double layered structure and interlayer air convection are used at the box door to ensure low temperature on the outer layer.

6. Overtemperature power-off function. Prevent excessive temperature from damaging the sample and ensuring its safety.

III. Main Technical Indicators And Parameters

1. Working power supply: AC220V ± 10%; 50Hz.

2. Ceramic fiber ash furnace: capable of reaching 1000 ℃, with experimental requirements for a temperature of 775 ± 25 ℃.

3. Electric heating plate: Heating power of 1000W.      

4. Porcelain crucible: 50ml.
