Experience True Air Quality Intelligence with the ONETEST-200XP – Premium Outdoor Air Ion Detector Made in China

When it comes to assessing environmental health—whether for urban planning, ecological research, tourism development, or public wellness—accurate measurement of negative oxygen ions (often called “air vitamins”) is essential. But reliable, field-ready instruments that combine precision, durability, and smart data management are rare.

That’s why Wanyi Technology, with 15 years of expertise in indoor and outdoor air quality monitoring and instrumentation, developed the ONETEST-200XP—a high-performance outdoor air ion detector made in China engineered for professionals who demand more than just numbers.

Engineered for Accuracy, Built for the Real World

Leveraging advanced sensor technologies from both domestic and international sources, the ONETEST-200XP delivers lab-grade accuracy in rugged outdoor conditions. It simultaneously monitors five critical environmental parameters:

• Negative oxygen ions (concentration: 0–5 million ions/cm³)
• PM2.5 & PM10 (particulate matter)
• Temperature & relative humidity

This multi-parameter capability makes it the ideal tool for environmental agencies, research institutes, smart city projects, forest parks, and wellness resorts.

Smart 7-Inch Touchscreen Interface

The ONETEST-200XP features a bright, responsive 7-inch color touchscreen LCD that displays:

• Real-time numerical values
• Trend curves for all parameters
• Customizable alarm thresholds
• Data logging status

Users can easily set storage intervals (e.g., every 10 seconds, 1 minute, etc.), ensuring flexible data collection for short-term studies or long-term environmental assessments.

Powerful Data Management & Analysis

Equipped with 30MB internal memory, the device stores thousands of data points. When ready, simply plug in a USB flash drive to export records in standard formats for further analysis.

Included PC analysis software allows users to:

• Visualize historical trends
• Generate compliance or research reports
• Compare ion levels across locations or seasons

Optional 4G Cloud Connectivity – Monitor Remotely, Anytime

For continuous, remote monitoring, choose the 4G-enabled version of the ONETEST-200XP. It automatically uploads data to Wanyi Tech’s secure cloud platform, where clients receive:

• A dedicated login account
• Real-time dashboards accessible via web browser or mobile app
• Email/SMS alerts when ion levels or pollution exceed set limits

Perfect for managing multiple monitoring sites—from mountain resorts to urban green spaces—without sending personnel on-site daily.
