Introduction: LJ150C particle counter is developed by the principle of light blocking (light-shielding) to detect the size and amount of solid particles in liquid. It can be widely used in the detection of insoluble particles in pure solution and ultrapure water, particle pollution detection of chemical reagents and cleaning agents, Precision parts cleanliness testing and low viscosity oil particle pollution testing. Features: 1. Adopting the principle of light resistance method (shading method), it has the advantages of fast detection, strong anti-interference, high precision and good repeatability. 2. High-precision sensor to ensure high-resolution force and accuracy; 3. Precision syringe sampling system to achieve constant sampling speed and accurate sampling volume control. 4. Sampling head automatic / manual lifting, adjustable position. 5. True color LCD touch screen, touch operation, simple and convenient. 6. Built-in GB / T14039, ISO4406, NAS1638, GJB420A, GJB420B particle pollution degree standards, and according to user requirements built-in required standards. 7. Up to 9900 particle size channels for granular analysis. 8. Can store three calibration curves (latex ball calibration curve, ACFTD calibration curve, ISOMTD calibration curve) at the same time, and can be easily switched to reduce the conversion error. 9. Test data storage capabilities to facilitate the detection of data archiving, retrieval and analysis. 10. Built-in printer, can print out the test report. 11. Built-in Chinese input method, test report Chinese mark. 12.RS232 interface and powerful data software, enabling external computer control of the instrument and the detection of data processing. 13. With magnetic stirring, so that the particles evenly distributed.
