June 2–4, 2026 – The 24th China International Environmental Protection Exhibition & Conference (CIEPEC) was held in Beijing. Palas®, specializing in aerosol particle monitoring technology, presented a wide range of solutions from research-grade applications to outdoor online environmental monitoring. Key exhibits included the GB3095-Recognized Light Scattering Method – Fidas® 200 Smart Ambient Air Particulate Matter Continuous Automated Monitoring System, and the Cloud Droplet Analyzer (CDA) for measuring cloud aerosols. Also on display was the U-range Continuous Online Monitoring System (4nm–40µm) for ambient applications, demonstrating Palas®’ ability to support the digital-intelligent transformation of environmental monitoring with high-precision, low-power, and digital technologies in support of China’s “dual carbon” goals.
On the first day of the exhibition, Ms. Deng Jun, Product Manager for Environmental and Automotive Business at Palas®, was interviewed on video by the hbzhan media platform. Since its founding in 1983, Palas® has been dedicated to the generation, processing, measurement, and analysis of aerosol particles. During the interview, Ms. Deng highlighted how Palas® products combine high optical resolution with low power consumption (operating at a level comparable to an incandescent bulb) to meet China’s increasingly stringent PM2.5 and PM10 monitoring accuracy requirements while helping reduce carbon emissions at the monitoring source. She also explained how the instruments’ digital capabilities – such as 256 size channels for particle size distribution analysis and automated flow monitoring – reduce manual maintenance efforts and promote intelligent upgrades in environmental monitoring.

Product Highlights
GB3095 recognizes the light scattering method
Palas® Fidas® 200 Smart Ambient Air Particulate Matter Continuous Automated Monitoring System
The Fidas® 200 Smart system, which has been included in the certified list for PM2.5 and PM10 applicability testing, was a central focus. Its light scattering method has received GB3095 recognition. The system features patented technology for on-site calibration with reference materials, offers a maintenance interval of up to three months, and consumes almost no consumables. Its value lies in supporting the construction of intelligent monitoring stations, mobile monitoring, and intelligent source apportionment through real-time particle size distribution data – providing a reliable option for the digital-intelligent transformation of standard environmental monitoring stations.

Wide Particle Size Spectrum (4nm–40µm) Continuous Online Monitoring System for Outdoor Applications
To enable continuous outdoor monitoring across a wider particle size range, Palas® showcased the U-range Wide Particle Size Spectrum (4nm–40µm) Continuous Online Monitoring System for outdoor applications. This weatherproof cabinet integrates core units including the U-SMPS Universal Scanning Mobility Particle Sizer and Fidas® series spectrometers, achieving wide particle size spectrum coverage from nanoparticles to micron particles within a single protective enclosure.
High-resolution, stationary aerosol spectrometer for the measurement of cloud aerosols
Palas® Cloud Droplet Analyzer (CDA)
For cloud and fog process research, Palas® presented the Cloud Droplet Analyzer (CDA). Based on optical light scattering at single particles, this instrument is specifically designed to measure the size distribution and number concentration of cloud aerosols (such as droplets and ice crystals). It offers two measuring ranges (0.6–40µm and 0.8–100µm) and outputs parameters including particle size distribution, number concentration (PN), liquid water content, and mean volume equivalent diameter. The automatically heated weatherproof cabinet effectively prevents icing, ensuring long-term, stable continuous monitoring in extreme weather and unattended outdoor environments. The CDA has been deployed in environmental research at the Marambio Base in Antarctica for ice nucleation studies and climate model improvement.
AQ Guard Smart Grid-based Ambient Air Quality Monitoring System
Compatible with NTI’s NL1 Smart Noise Location and Monitoring System
In addition, the Palas® AQ Guard Smart System supports simultaneous measurement of multiple PM values (including PM1, PM2.5, PM10), can be calibrated on-site using standard particles, and features easy installation with near-zero consumables. Compatible with the NL1 Smart Noise Location and Monitoring System provided by NTI, this solution can capture both particulate matter concentration data and noise source location information, offering customers an integrated “air pollutant + environmental noise” monitoring option.
From the GB3095-recognized light scattering monitoring system to the wide particle size spectrum outdoor continuous monitoring solution, and then to the cloud droplet spectrometer and multi-parameter monitoring platform, Palas® demonstrated at CIEPEC its synergistic capabilities across multiple particle size ranges and application scenarios. Through continuous technological innovation and digital integration, Palas® is committed to delivering precise, efficient, and intelligent solutions for environmental monitoring.
