TSI-IAQ-CALC
TSI IAQ-Calc Meters assess and track indoor air quality (IAQ). The 7515 offers an affordable solution for carbon dioxide (CO₂) monitoring. Models 7525 and 7545 measure and log multiple parameters simultaneously. The 7525 captures CO₂, temperature, and humidity while also calculating dew point, wet bulb temperature, and percentage outside air. The 7545 extends these capabilities by including carbon monoxide (CO) detection.
Key Features
- Verify building HVAC system performance
- Examine building IAQ conditions to optimize worker productivity
- Comply with regulations and guidelines
- Low-drift NDIR CO2 sensor for stable, accurate readings
- Sampling function records multiple-point measurements
- Ergonomic, over-moulded case design
- Temperature and relative humidity measurements help determine thermal comfort
- Calculates the percentage outside air from either CO2 or temperature
- Directly calculates dew point and wet bulb temperatures
- Shows up to three parameters
