Liquid particle counterIt is a precision analytical instrument based on the principle of light scattering, used for quantitative detection of the size, quantity, and distribution of suspended particles in liquids (such as oil, water, pharmaceuticals, and electronic chemicals). Its core function is to evaluate the cleanliness level of liquids, and it is widely used in hydraulic system oil monitoring, semiconductor ultrapure water detection, pharmaceutical injection clarity inspection, aerospace fuel filtration, and other fields. It is the core equipment for "liquid cleanliness control" in industrial production and scientific research.

　　Liquid particle counterAccording to different testing principles, flow rates, and volume forms, it can be divided into multiple types:

According to the testing principles: photoresist method, light scattering method, resistance method, filter clogging type, and image analysis type.

According to flow rate: small flow rate (2.83L/min) and large flow rate (28.3L/min).

By volume: portable, desktop, and online. Portable is suitable for on-site testing, desktop is suitable for laboratory use, and online can achieve real-time and continuous monitoring.

Liquid particle counters play an important role in multiple key industries:

Industrial manufacturing:

Oil contamination level detection: used for detecting the contamination level of transformer oil, hydraulic oil, lubricating oil and other oils, which meets relevant standards and can identify particle pollutants ranging from 0.1 μ m to 1000 μ m.

Part cleaning and anti-wear protection: Monitor particle contamination during the part cleaning process to ensure cleaning effectiveness; At the same time, by monitoring the particulate matter in the oil, evaluating the wear of the equipment, and providing anti-wear protection.

Medical testing:

Cleanliness evaluation of drugs: In the pharmaceutical industry, this equipment can be used to evaluate the cleanliness of drugs such as injection water and intravenous injections, ensuring quality and safety.

High viscosity sample testing: Measure the particle size distribution of high viscosity samples such as fat emulsions and polymer solutions to ensure drug safety.

Environmental monitoring:

Water quality monitoring: used to detect particulate matter in water, warn of the risk of "two pests" pollution, and optimize the backwash cycle of the filter.

Nanomaterial research: used for measuring the particle size distribution of nanomaterials, correcting latex standard particles, etc., regular calibration with polystyrene standard particles (PSL) is required.

Electronic industry:

Ultra pure water detection: Monitor the nanoscale particles in ultra pure water to ensure the cleanliness of the chip manufacturing process.

Photoresist detection: Analyze the particles in the photoresist to ensure accuracy and stability during the chip manufacturing process.
