Supplying KT-2A Particle Counter for Tianjin Logan Laboratory - Light Obstruction Particle Counter

Overview: The KT-2A desktop particle counter is developed based on the light-blocking principle, designed to detect the size and quantity of solid particles in liquids. It can be widely applied in industries such as aviation, aerospace, aero-engine, heavy machinery, power, oil, petrochemical, transportation, ports, metallurgy, machinery, and automotive manufacturing. It is used for the particle contamination testing of various oils including hydraulic oil, lubricating oil, rock oil, transformer oil (insulating oil), steam turbine oil (turbine oil), gear oil, engine oil, aviation kerosene, and water-based hydraulic oil. It also serves for sampling tests of insoluble particles from water-based samples, chemicals, organic liquids, and polymer solutions.

Performance Features:
Utilizing the principle of photoresist method (light shielding method), it boasts advantages such as fast detection speed, strong anti-interference ability, high accuracy, and good repeatability.
High-resolution sensor with precision and accuracy.
Injector-style sampling system, ensuring constant sampling speed and precise volume control.
Vacuum/pressure vessel for degassing samples and testing high viscosity samples.
5.6-inch color LCD display with touchscreen operation.

? Stores up to four calibration curves (Latex Ball Calibration Curve, ACFTD Calibration Curve, ISOMTD Calibration Curve, GOST Calibration Curve) and allows easy switching to minimize conversion errors.
Feature: Data Storage for Test Data, facilitating archiving, retrieval, and analysis of test data.
Built-in printer, capable of directly printing out test reports.
Built-in Chinese input method for Chinese labeling on inspection reports.
RS-232 interface and powerful data collection software, allowing for external computer annotation, storage, querying, and PDF report generation of test data.
?Features magnetic stirring for even particle distribution.
The pressure pump is equipped with four-stage gas filtration and a dehumidification purifier, preventing environmental air from contaminating the samples.
