Indoor Air Quality Meters

Tools for HVAC and IAQ Professionals

HVAC technicians, industrial hygienists, and facility managers rely on accurate data to diagnose building performance issues. The TSI IAQ-Calc™ series is engineered to be the go-to tool for these professionals. Lightweight and handheld, these meters are perfect for conducting building walkthroughs to verify system performance or investigate occupant complaints of "stuffy" air. By providing fast, reliable readings of CO2, temperature, and humidity, they help you determine if a space is receiving adequate ventilation per ASHRAE standards.

Data Logging and Analysis

Understanding air quality often requires looking at how conditions change over time. The IAQ-Calc™ meters feature robust data logging capabilities, allowing users to record thousands of data points for later analysis. This feature is critical for troubleshooting issues that may only occur at certain times of the day. The included LogDat2™ downloading software simplifies the process of transferring data to a computer, where you can generate charts and reports to document your findings and support your recommendations for system improvements.

Versatile Parameter Calculation

Beyond basic measurements, the IAQ-Calc™ meters offer advanced calculations that save time in the field. The ability to automatically calculate percent outside air is invaluable for verifying the makeup air ratios in ventilation systems. Similarly, wet bulb and dew point calculations assist in assessing thermal comfort and the potential for moisture issues like mold growth. By packing these capabilities into a single, durable instrument, TSI enables professionals to conduct comprehensive IAQ assessments efficiently, helping to ensure that indoor environments remain safe, comfortable, and compliant.
