KZ-1 online particle counter


On-line Particle Counter

In-line high precision


l The instrument is equipped with mounting holes and can be mounted on the system for real-time monitoring of oil particle contamination (cleanliness) of various hydraulic and lubricating systems.

l Adopting the principle of photoresist method (shading method), it has the advantages of fast detection speed, strong anti-interference, high precision and good repeatability.

l High precision sensors ensure high resolution and accuracy.

l Precision metering sampling system, to achieve constant sampling speed and precise control of sampling volume.

l With built-in "custom" standard, particle size can be arbitrarily set at 0.1 m interval, and 990 particle sizes can be set to facilitate particle size analysis.

l With built-in calibration function, the calibration can be carried out according to ISO4402, GB/T18854-2002 (ISO11171:1999), ROCT and other standards.

l Three calibration curves (ACFTD calibration curve, ISOMTD calibration curve and GOST calibration curve) can be stored at the same time, and can be easily switched to reduce the conversion error.

l Built-in printer, can directly print out the detection report.

l The instrument can realize continuous automatic on-line detection, can give the number and grade of particles in real time, and can set the detection interval at will.

l With flushing function, flushing volume can be set arbitrarily.

l High strength cast aluminum housing, strong anti-interference, high temperature and high pressure resistance, strong housing, can be used in harsh environment.

l Standard RS232 communication, can be optional 485 communication, and provide communication protocol, can be connected to the computer or upper computer to complete the control of the instrument and test data transmission, storage and processing.
