Description
The Sauermann SI-AQ TVOC monitor is a professional handheld instrument designed for comprehensive indoor air quality (IAQ) assessment. Ideal for environmental consultants, occupational hygienists, HVAC professionals, laboratories, and facility managers, it delivers fast, accurate measurement of Total Volatile Organic Compounds (TVOCs) while monitoring key environmental parameters.
Using a high-performance Photoionization Detector (PID) sensor, the Sauermann SI-AQ provides reliable TVOC measurements across a wide operating range, making it suitable for identifying indoor air quality issues, investigating odor’s, validating ventilation performance, and assessing exposure to airborne contaminants. The modular design allows users to configure the instrument with up to three additional gas sensors, creating a versatile solution for a broad range of air quality applications.
