Main features
Adopt the counting principle of photoresist (shading) method formulated by the International Hydraulic Standards Committee
High-precision laser sensor with wide test range, stable performance, low noise and high resolution
Using high-pressure syringe pump sampling method, the sampling volume can be set by yourself, the injection speed is stable, and the sampling accuracy is high
The injection system combined with positive and negative pressure can realize sample degassing and is suitable for testing samples of different viscosity
Built-in pressure sensor, which can directly set the pressure value and automatically judge the air pressure in the cabin to ensure safety
The host has a built-in air purification system to ensure that the test is free from pollution, with a high degree of integration, to avoid secondary pollution caused by the air tightness of the air pump and the test system
Built-in multiple calibration curves, compatible with all commonly used standards at home and abroad for calibration
GJB-420A,GJB-420B,NAS1638,GB/T14039,ISO4406,SAE4059cpc,SAE4059F,SAE749D,ГOCT17216,QC/T29104,JB/T9737,DT432,HH005-2018
Support custom standard testing, can name and rank custom standards
According to customer requirements, up to 64 detection channels can be set up simultaneously
Built-in data analytics system, one test can give all standard test data and pollution level
It can perform cleaning detection, preset the target cleaning requirement particle concentration, display the cleaning status in real time during the cleaning process, and automatically stop when the requirements are met
Built-in viscosity, moisture, and temperature sensor modules provide accurate measurement of particle distribution while providing viscosity, moisture saturation, and ppm values and temperature reference values (optional).
Particle size can be arbitrarily set, with a built-in particle size of nearly 10,000, which is convenient for granularity analysis
A variety of sampling containers such as standard sampling bottles or sampling cups can be used to meet the testing requirements of different industries
Full-featured 7-inch color touch screen operation, folding button design, support for Chinese and English dual interfaces, simple and convenient operation
Manual, automatic, and half-count calibration is possible
It has an RS232 interface, supports 485 communication, and can be connected to a computer or laboratory platform for data processing
It has the functions of mass data storage and printing, and supports U disk storage. The stored data of the machine can be exported to the U disk
Have more than 5 account settings, and set operator permissions separately
