Introducing the ONETEST-100AQ: The Instrument That Simultaneously Measures SO2, NO2, and CO with Unmatched Precision

In the rapidly evolving landscape of environmental monitoring, one question frequently arises among air quality professionals and industrial safety managers: "What instrument measures SO2 NO2 CO simultaneously?" The answer is the ONETEST-100AQ Multi-Parameter Air Quality Monitor, a state-of-the-art detection system engineered to deliver simultaneous, real-time measurements of sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO) alongside a comprehensive suite of additional parameters.

A Complete Multi-Gas Solution for Modern Air Quality Challenges

Developed to address the growing demand for integrated environmental monitoring, the ONETEST-100AQ combines high-precision electrochemical gas sensors with an advanced ARM microprocessor. This powerful combination enables simultaneous tracking of critical pollutants including SO2 (0-200ppb, ±3%), NO2 (0-2000ppb, ±3%), and CO (0-10ppm, ±3%), making it the definitive answer for professionals seeking reliable instruments for multi-gas air quality assessment.

Comprehensive Parameter Coverage

Beyond its core SO2, NO2, and CO detection capabilities, the ONETEST-100AQ monitors a full spectrum of environmental indicators:

• Particulate Matter: PM2.5 and PM10 (0-1000μg/m³, ±10%)
• Ozone (O3): 0-2000ppb with ±3% accuracy
• Temperature & Humidity: -40~80°C (Level 0.5) and 0-100%RH (±3%RH)
• Optional Add-ons: TVOC, nitric oxide (NO), wind speed, wind direction, atmospheric pressure, and ultraviolet radiation

Intelligent Design Engineered for Demanding Environments

The ONETEST-100AQ features a brilliant 7-inch color touchscreen LCD with CCFL backlight technology, delivering crystal-clear visibility of real-time data curves, alarm values, and trend analysis in any lighting condition. The built-in 30MB FLASH memory ensures zero data loss during power interruptions, providing uninterrupted data integrity for long-term monitoring projects.

Data export capabilities include both USB PC connectivity and convenient U-disk export functionality, complemented by dedicated single-computer data analysis software. For remote deployments, the optional GPRS module enables wireless cloud platform integration with real-time WEB data viewing, automated charting, data export, and intelligent early warning notifications via SMS and email.
