TSI IAQ-Calc™ Indoor Air Quality Meter 7525 is an outstanding instrument for investigating and monitoring indoor air quality or IAQ. Handheld, easy to use allowing you to gather your data and work with ease.

The 7525 IAQ Meter measures and data logs multiple parameters such as carbon dioxide (CO2), temperature, and humidity. It calculates dew point, wet bulb temperature, and percent of outside air.

FEATURES AND CAPABILITIES

Low-drift NDIR CO2 sensor for stable, accurate readings
Sampling function records multiple point measurements
Ergonomic, overmolded case design
Temperature and relative humidity measurements help determine thermal comfort
Calculates percent outside air from either CO2 or temperature
Directly calculates dew point and wet bulb temperatures
Shows up to three parameters
