The oil particle sizer adopts a "photoresistive particle measurement" and can be equipped with multiple standards according to user requirements. The classic seventh generation application software platform enables convenient setting and operation of cleaning, detection, calibration, and calibration modules. It has built-in thresholds, particle size curves, and pulse resistance values, allowing for the setting of any channel particle size value. New microcomputer color screen display, built-in operating system and micro printer, can be tested and printed directly without the need for an external computer or printer. Equipped with a standard serial RS232 port, it can be connected to an external computer to store detection results, facilitating data classification and retrieval.

The oil particle size analyzer measures particle size based on the small hole resistance principle, also known as the Coulter principle. Due to its principle of measuring the size of each particle one by one and then calculating the particle size distribution, it has high resolution and can provide the number of particles. The maximum resolution (number of channels) depends on the measurement accuracy of the pulse height by the electronic system of the instrument.

The instrument is particularly suitable for measuring the following objects: 1 For powders that require high resolution or special attention to particle size distribution width, such as abrasive micro powders, copy powders, etc. 2. Rare particles in liquids.
