OC-300 Portable Dust Detector: One Device, Multiple Particle Monitoring Options
When it comes to particulate monitoring, different applications require different types of data. Some projects focus on PM2.5 and PM10, while others require detailed particle-size measurements or TSP monitoring.
The Oceanus OC-300 Portable Dust Detector is designed to provide flexible and reliable particulate monitoring in a compact, portable format. Equipped with a laser sensor, it can be configured for different particle measurement requirements, making it suitable for a wide range of environmental and industrial applications.
Flexible Particle Size Measurement
One of the key advantages of the OC-300 is its flexible particle-channel configuration.
Depending on the monitoring requirements, users can choose from different measurement options:
- 4-channel configuration: 0.3μm, 2.5μm, 5.0μm and 10μm
- 6-channel configuration: 0.3μm, 0.5μm, 1.0μm, 2.5μm, 5.0μm and 10μm
- TSP monitoring
- PM2.5, PM10 and TSP measurement
This flexibility allows the OC-300 to adapt to different monitoring objectives without requiring a completely different instrument for every application.
Laser Sensor for Particle Detection
The OC-300 uses a laser-based sensing system for particulate detection. It can provide particle concentration information in both mass concentration (μg/m³) and particle count (PC/L) modes, helping users obtain more comprehensive particulate data.
With a 3.5-inch industrial-grade color display, measurement parameters can be viewed directly on the device during field inspections.
More Than a Dust Detector
The OC-300 is designed as a multifunctional portable monitoring device.
In addition to particulate measurement, it supports:
- Temperature and humidity measurement
- Data logging for historical records
- Quantity and quality measurement modes
- Optional gas detection module
- Optional micro-printer for measurement records
- RS232 and USB interfaces
The built-in data logger can store up to 100,000 groups of data, allowing users to review historical measurements without relying on a separate recording device.
Designed for Field Monitoring
Portability is important when measurements need to be taken across different locations.
The OC-300 features a rechargeable lithium battery and a compact handheld design, making it convenient for on-site inspections, environmental assessments and air quality investigations.
Its IP65 protection rating and Ex ia II CT4 explosion-proof grade further expand its suitability for demanding monitoring environments.
Applications of OC-300
The OC-300 can be used across various particulate monitoring scenarios, including:
- Environmental monitoring
- Indoor air quality assessment
- Industrial site inspections
- Public area monitoring
- Health and hygiene supervision
- Dust and particulate investigation
- Disease control and related inspection applications
Whether the objective is to measure particle concentration, analyze different particle sizes or monitor PM2.5, PM10 and TSP, the OC-300 provides a flexible portable solution.
