KN-4406B Portable Liquid Particle Counter

    KN-4406B Portable Liquid Particle Counter is designed based on the principle of light blockage method, which is specially used for fast detection of oil contamination level on site. It has the advantages of small volume, light weight, fast detection speed, high precision, good repeatability, and can work under extremely harsh conditions such as high temperature and high pressure. Built-in micro water sensor and temperature sensor, so it can detect water content and temperature as well as pollution degree in oil. It can be widely used in aerospace, petrochemical, transportation ports, iron and steel metallurgy, automobile manufacturing and other fields of hydraulic oil, lubricating oil, transformer oil (insulation oil), turbine oil, gear oil, engine oil and other oil detection

Features   

1.The principle of light blockage method, the use of high-precision laser sensor, small size, high precision, stable performance.

2.It is suitable for laboratory or on-site detection, and can also be used for on-line high pressure measurement with pressure-reducing device to realize real-time detection of oil particle contamination.

3.Built-in calibration function. It can be calibrated according to ISO4402 and other standards.

4.Built-in data analysis system. It can automatically determine the sample grade according to the standard, and has the function of automatic data processing and printing.

5.The alarm level can be set arbitrarily, and the alarm prompt will be given when the limit is exceeded to realize pollution or cleanliness detection.

6.The alarm level can be set arbitrarily, and the alarm prompt will be given when the limit is exceeded to realize pollution or cleanliness detection.

7.External pressure chamber can be connected to form positive pressure or negative pressure, to achieve high viscosity sample detection and sample degassing.

8.Washing mode according to volume or time, convenient for users to use and maintain.

9.English and Chinese can be switched.

10.Super large storage, optionally stored in the internal or external storage devices of the instrument.

11.Embedded design, high strength shell, easy to carry, suitable for all kinds of construction machinery.
