KZD-2 oil particle contamination detector

Brief introduction

The KZD-2 particle counter is a set of special equipment for evaluating the performance of the filter (filter). In many experiments, the KZD-2 particle counter can detect the concentration of pollutants in the upper and lower reaches of the filter, and then the filter efficiency and the ratio of filter (filter) are obtained, which is in accordance with the relevant requirements of the GBT/18853-2002 (ISO16889:1999) hydraulic transmission filter.

Features:

1. Using the photoresist method (shading) principle

2. The twin precision laser sensor, the realization of upstream and downstream particle counting at the same time

3. Precision sampling system, the realization of the velocity is constant, and precision measurement

4. Can be connected through the RS232 serial port and industrial control system, realize the industrial computer control of the particle counter and data processing

5. Operation is flexible, which can realize the upstream, downstream and upstream and downstream for testing at the same time

6 can be set to counter mode, realize the function of the desktop particle counter

7 built-in printer, can directly print inspection report

8 fully comply with the relevant provisions of ISO16889 (GBT/18853)
