Logan Kexing KB-3A Portable Oil Contamination Detector
Overview:
Offline Detection:
Direct sampling for testing from the sample bottle; use a pressure bottle sampler (with pressure device) for sampling and testing.
Online Inspection:
Can be installed on various hydraulic transmission, lubrication, oil filtering machines, cleaning units, and testing stations, enabling online detection of the oil contamination (cleanliness) level of the system.
Performance Features:
Utilizes the principle of photoresist (light blocking) method, featuring fast detection speed, strong anti-interference capability, high accuracy, and good repeatability.
High-precision sensors ensure high resolution and accuracy.
High-precision sampling system, ensuring constant sampling speed and precise volume control.
4.3-inch color LCD display with touchscreen operation.
Integrated NAS1638, ISO4406-1999, ISO4406-2017, ISO4406-1987, GB/T 14039-2002, GJB420B-2006, GJB420B-2015, GJB420A-1996, AS4059E differential, AS4059E cumulative, AS4059F differential, AS4059F cumulative, ROCT17216-1971, ROCT17216-2001, JTS-005, SAE749D-1963, and NAS1638/ISO4406 particle contamination grade standards, with the ability to incorporate additional standards as per customer requirements.
In-built "Custom" standard, allows for particle size settings at intervals of 0.1μm, with up to 990 sizes available for easy particle size analysis.
In-built calibration function, capable of calibration according to standards such as ISO4402, GB/T18854-2002 (ISO11171:1999), and ROCT.
Store up to three calibration curves (ACFTD, ISOMTD, GOST) simultaneously and easily switch between them to minimize conversion errors.
Built-in printer for direct printing of test reports.
The testing data storage function allows for data to be saved either within the instrument's internal memory or to an external USB flash drive via the instrument's USB port.
The instrument can perform continuous automatic online detection, providing real-time particle count and grade, and allows for customizable detection interval settings.
Optional water activity sensor for detecting the water activity (aw value) and oil temperature in the oil.
Features an adjustable rinse function with customizable rinse volume.
High-strength injection-molded imported shell, compact structure, lightweight, allowing the main unit and accessories to be easily carried in a backpack.
High-precision aluminum anodized panel, sleek and aesthetically pleasing, durable and long-lasting.
Standard RS232 communication is provided, along with communication protocols. It can be connected to a computer or a higher-level machine to control the instrument and transmit, store, and process detection data.
