OmniTrak OmniTrak Knowledge Beyond Measure. II Sensor Data Numeric - - Core Module Particules Fines + COV-PID (ppm) Efficiency Meets Intelligence. Customizable, Scalable, and Affordable Monitoring. Smart Station and two modules are shown The OmniTrak™ Solution Smart Station pairs seamlessly with any OmniTrak™ module to provide immediate, on-site visibility into indoor environmental conditions. View live measurements, generate reports, and analyze data in real time to identify issues and drive informed improvements to air quality. PM + VOC-PID (ppm) Module 7591-04 Core Module 7591-05 Features and Benefits ■ Wireless connection for up to 10 modules simultaneously ■ Large touch-screen with intuitive navigation used for recording studies, managing data, viewing historical data, real-time measurements, etc. ■ Download data directly from the device onto your PC or upload data to our TSI Link™ cloud platform for easy accessibility ■ Unique laser-based light scattering particle sensors - outputs mass concentration data (PM1, PM2.5, PM4, PM10) and particle number concentration data separated into 5 distinct bins ■ Precise 10.6 eV PID (photo ionization detector) for monitoring various VOCs (volatile organic compounds) in the PPM and PPB ranges ■ Accurate, high sensitivity VOC detection at low concentrations with the Core Module's electrochemical VOC Sensor ■ Modular design allows the flexibility and connection to future next generation modules ■ Ventilation effectiveness testing ■ IAQ studies in commercial/residential buildings, schools, hospitals, industrial manufacturing, etc. ■ Industrial/occupational hygiene surveys and indoor air quality investigations ■ Identify air quality hot-spots. Pinpoint problem areas and investigate sources of poor indoor air quality ■ Pre and post-remediation air testing. Validate the impact of air purifiers, ventilation upgrades, or renovation projects on indoor air quality ■ Compare air quality by zone. Monitor and compare IAQ data across different rooms, floors, or building zones over time ■ Support Manufacturing Quality Control. Track environmental conditions that could affect product quality in production areas ■ Engineering control evaluations
