In this approach, suspended particles flow through a defined sensing zone where they interrupt a laser beam. These interruptions generate signal variations that are processed by the system to determine both particle size and particle concentration. This technique is widely applied in contamination analysis of oils and industrial fluids, as it enables direct measurement of suspended solid particles within the sample.\u003c\/p\u003e\n\u003cp\u003eThe system is designed to support both offline bottle sampling and optional online measurement configurations. For online operation, it works within a standard pressure range of 0.1 to 0.6 MPa. With optional pressure-reducing components, it can handle higher-pressure environments of up to 40 MPa. In addition, the system can be configured for higher-viscosity fluid analysis through dedicated accessories, expanding its usability across a broader range of industrial applications.\u003c\/p\u003e\n\u003ch2\u003ePortable Particle Counter - QualiOPC™ 400 Technical Specification\u003c\/h2\u003e\n\u003ctable class=\"table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eQualiOPC™ 400\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Name\u003c\/td\u003e\n\u003ctd\u003ePortable Particle Counter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eQualiOPC™ 400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Principle\u003c\/td\u003e\n\u003ctd\u003eOptical light-blocking \/ shading method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Source\u003c\/td\u003e\n\u003ctd\u003eSemiconductor laser\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperation Mode\u003c\/td\u003e\n\u003ctd\u003eOffline sampling; online sampling optional\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOnline Viscosity Range\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;100 cSt, with optional accessory for higher viscosity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOnline Pressure Range\u003c\/td\u003e\n\u003ctd\u003e0.1–0.6 MPa, optional up to 40 MPa with pressure-reducing device\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSample Temperature\u003c\/td\u003e\n\u003ctd\u003e0°C to 80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParticle Size Range\u003c\/td\u003e\n\u003ctd\u003e1–500 μm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e1 μm (ISO 4402) or 4 μm(c)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Channels\u003c\/td\u003e\n\u003ctd\u003e32 channels, 0.1 μm intervals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSampling Volume\u003c\/td\u003e\n\u003ctd\u003e10–100 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Error of Sampling\u003c\/td\u003e\n\u003ctd\u003eBetter than ±2%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSampling Speed\u003c\/td\u003e\n\u003ctd\u003e5–60 mL\/min, default 25 mL\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCleaning Speed\u003c\/td\u003e\n\u003ctd\u003e5–60 mL\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003eBetter than 10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverlap \/ Coincidence Error Limit\u003c\/td\u003e\n\u003ctd\u003e12,000–40,000 particles\/mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCounting Repeatability\u003c\/td\u003e\n\u003ctd\u003eRSD \u0026lt; 2%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCounting Accuracy\u003c\/td\u003e\n\u003ctd\u003e±10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-30°C to 80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e110–240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003eBuilt-in lithium battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptional Features\u003c\/td\u003e\n\u003ctd\u003eHigh-pressure sampling support, calibration curve packages\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":52178557436215,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/portable-particle-counter387270939.webp?v=1779380429","url":"https:\/\/qualitest.us\/products\/portable-particle-counter","provider":"Qualitest USA LC","version":"1.0","type":"link"}
