Product description

Hjclean Mobile Online Particle Monitoring System is to record the presence of airborne particles in key areas of the production line. It can automatically and continuously monitor and record the particle size and quantity distribution of suspended particles in the monitored ambient air, and generate reports at the same time. When the state of dust particles in the monitoring environment exceeds the warning line and the correction line, the system can automatically activate sound and light alarms and notify relevant personnel for processing, thereby helping to ensure that the particle conditions in the monitored critical environment are in a normal state to ensure production Go smoothly.

The suspended particle online monitoring system is formulated according to the relevant GMP standards, which meets the requirements and specifications of FDA and EU GMP, and can effectively help the environment to carry out standardized operations.

Working principle

The purpose of the Mobile Online Particle Monitoring System is to record the presence of suspended particles in the air in key areas of the production line. It can automatically and continuously monitor and record the particle size and quantity distribution of suspended particles in the monitored ambient air, and generate reports at the same time. When the state of suspended particles in the monitored environment exceeds the warning limit and deviation limit, the system can automatically activate sound and light alarms and notify relevant personnel for processing, thereby helping to ensure that the particle status in the monitored critical environment is in a normal state to ensure production Go smoothly. The technical solutions provided by Hongji Company are formulated in accordance with the relevant GMP standards and comply with the requirements and specifications of FDA and EU for GMP.

Brief description of work process

The suspended particle online monitoring system can set online suspended particle monitoring points and planktonic bacteria sampling according to the user's pipeline, and conduct online continuous monitoring of key clean areas. The particle size of the monitored particles is 0.5, 5.0μm. The system is equipped with an external vacuum sampling pump, and is equipped with corresponding sampling tubes, data cables, power cables and other auxiliary materials according to the actual situation of the plant. All wires are passed through the stainless steel tube. It can be extended to realize real-time monitoring of environmental parameters in the clean room's A-level and B-level areas, including temperature and humidity, pressure difference, and wind speed, and realize functions such as display, record, storage, printing, alarm, and historical record query.

Technical characteristics

28.3 liters/min sampling volume

Really reflect the dynamic changes of the environment in real time

The system uses dual sampling pumps alternately to stabilize the vacuum in the vacuum tank at the set value and prolong the service life of the vacuum pump

Each channel in the system has a flow sensor to monitor the sampling flow, and convert the detected actual sampling flow to 1m³ data

The system uses a pneumatic box to subdivide the total vacuum pipeline into sampling tubes for each sampling point, which is convenient for debugging, overhauling and maintenance.

System expansion is very convenient. It can not only increase sampling points, but also integrate the detection of planktonic bacteria sampling, wind speed, pressure difference, temperature and humidity, etc.

The system can view the system status in real time

The software system meets the requirements of computerized verification
