Sustained performance growth demonstrates the company's dual strengths in technological capabilities and market expansion.

The product line of Hebei Dengyan Technology covers a wide range of monitoring from the macroscopic environmental air quality (air micro stations) to "dust" (dust detectors), "particles" (particle counters), and "gas" (gas detectors), forming a complete air quality management product matrix. These four product series complement each other and can provide government, enterprises, and various institutions with comprehensive and customized solutions ranging from regional environmental monitoring, occupational health protection to high-end clean environment assurance, it includes:

1. Air Quality Monitoring  Station

The Air Quality Monitoring Micro Station is an integrated, miniaturized, and intelligent online environmental air quality monitoring system. It adopts a modular design and can simultaneously integrate monitoring of key air pollution parameters such as PM2.5, PM10, SO, NO, CO, and O, as well as meteorological parameters such as temperature, humidity, wind speed, and wind direction. Through wireless data transmission technologies (such as 4G/5G, LoRa), data can be uploaded in real time to the cloud monitoring platform, enabling large-scale, grid-based deployment and precise source tracing.

2. Dust  Monitor

The Dust Concentration Monitor is a device specifically designed for real-time measurement of the mass concentration of suspended particulate matter (dust) in the air. It mainly employs laser scattering method or electrostatic induction principle, featuring fast response, high accuracy, and good stability. According to monitoring requirements, it is divided into portable and online types.  

3. Particle Counter

The particle counter is a high-precision optical instrument used to measure the number of suspended particles in a unit volume of air and their size distribution (such as 0.3μm, 0.5μm, 1.0μm, 5.0μm, etc. ). It generates scattered light pulses by irradiating particles with a laser source, and counts and classifies them based on the number and size of the pulses. The product forms include handheld, portable, and online remote types.

4. Gas Detector

A gas detector is a device used to measure the concentration of specific gas components in the air. Based on the detection principle, there are mainly electrochemical type, infrared type (NDIR), catalytic combustion type, PID photoionization type, etc. The product forms are diverse, including portable (single/combined gases), fixed (online monitoring), and gas detection probes.
