In semiconductor manufacturing, precision electronics, biopharmaceutical production, and other controlled environments, airborne particle monitoring is essential for maintaining clean conditions and supporting process control.
The NAVPHO SND1101 0.1 μm airborne particle counter is designed for high-sensitivity particle monitoring in demanding cleanroom applications. It combines fine-particle detection, multi-channel measurement, touchscreen operation, data storage, and communication capabilities in a compact benchtop instrument.

0.1 μm Detection with 8 Particle-Size Channels
The SND1101 uses the single-particle laser light-scattering principle to measure airborne particles across eight particle-size channels:
0.1, 0.15, 0.2, 0.25, 0.3, 0.5, 1.0, and 5.0 μm.
With a standard sampling flow rate of 2.83 L/min, the instrument is designed to provide reliable particle-count data for routine cleanroom monitoring and environmental measurement.
The stated counting efficiency is 50% at 0.1 μm and 100% above 0.15 μm, according to the product specifications.
For light-scattering airborne particle counters, ISO 21501-4 defines calibration and verification methods for parameters including counting efficiency, particle-size setting error, sampling flow rate error, and other performance characteristics. Specific compliance claims should be based on the applicable instrument verification or calibration documentation.
Designed for High-Sensitivity Cleanroom Applications
With a minimum particle-size channel of 0.1 μm, the SND1101 is intended for applications where fine airborne particle monitoring is important.
It can be used in high-grade cleanroom environments, including applications associated with ISO Class 1–4 cleanrooms, depending on the requirements of the cleanroom, sampling plan, and applicable standards.
Typical applications include:
- Semiconductor manufacturing
- Precision electronics production
- Biopharmaceutical manufacturing
- New energy battery production
- Laboratories and research facilities
- Cleanroom environmental monitoring
Practical Features for Routine Operation
The SND1101 is designed not only for particle measurement, but also for efficient day-to-day operation.
8-Inch Color Touchscreen
The large touchscreen provides an intuitive interface for configuring measurements and viewing particle-count results.
Built-In Thermal Printer
Measurement results can be printed directly at the point of use, supporting routine inspection and on-site documentation.
Large Data Storage Capacity
The SND1101 supports storage of up to 5 million measurement records, allowing historical data to be retained for review and traceability.
RS485 and Ethernet Connectivity
The instrument supports RS485 and Ethernet communication for integration with connected monitoring systems.
A Practical 0.1 μm Particle Monitoring Solution
For cleanroom operators, engineers, quality-control personnel, and laboratory users, the right particle counter needs to provide both measurement capability and practical usability.
The SND1101 combines:
0.1 μm detection
8 particle-size channels
2.83 L/min sampling
Touchscreen operation
Thermal printing
5-million-record storage
RS485 and Ethernet connectivity
This combination makes the SND1101 a practical option for high-sensitivity airborne particle monitoring in controlled environments.
