Labtron Dust Meter provides real-time sampling and accurate measurements for airborne dust levels. We provide devices that operates reliably in diverse settings. We offer LCD panels, data storage, alarms, and rechargeable batteries. They include microprocessors, high-quality sensors and user friendly operation. These devices measure and display dust concentrations with precision. Our Monitors portability and intuitive design make them ideal for dust concentrations across various applications.

Labtron’s Portable Dust Monitor LDMR-A11 is ideal for cleanrooms, laboratories, pharmaceutical manufacturing, semiconductor environments, and quality-controlled production lines. It is also widely used in field inspections, facility audits, HVAC testing, and environmental health studies. Its compliance with cleanroom standards, real-time monitoring capabilities, and reliable performance across temperature and humidity ranges make it a versatile solution for critical air quality monitoring.
Our Portable Dust Monitor LDMR-A11 uses advanced laser scattering technology and MEMS sensors to detect and count airborne particles with high sensitivity. It operates with a consistent sampling flow of 2.83 L/min and includes an environmental compensation algorithm that adjusts for fluctuations in temperature and humidity. This ensures measurement reliability even in dynamic conditions. Additionally, it complies with ISO 14644-1 standards, further validating its accuracy for use in sensitive environments like ISO5 to ISO9 cleanrooms.
Yes, the Portable Dust Monitor LDMR-A11 is designed with modern connectivity options including RS485 Modbus and WiFi (2.4 GHz). This allows it to be integrated into centralized environmental monitoring systems, particularly in GMP-compliant facilities. It is compatible with smart applications (like Tuya Smart), enabling remote access, data collection, and analysis across multiple devices. This makes it ideal for continuous facility-wide monitoring and compliance management.
The Portable Dust Monitor LDMR-A11 features a lightweight design (1 kg), a compact structure, and a powerful battery configuration using three detachable 18650 lithium cells (3400mAh each), allowing up to 10 hours of continuous operation. Its 4.0-inch TFT touch screen provides on-site visibility, while data can be saved locally or exported via SD card in PDF or Excel format. These features allow it to function effectively as both a mobile inspection tool and a semi-permanent monitoring station.
Our Portable Dust Monitor LDMR-A11 supports storage of up to 5000 data groups, and the data can be viewed directly on the device or transferred to a computer. It also allows exporting data via SD card in standard formats such as Excel or PDF, which makes documentation and reporting straightforward. This feature is especially valuable for audits, trend analysis, or regulatory submissions in industries like pharma and biotech.
