Description
Specifications

The IAQ-Calc TM TSI instruments are truly extraordinary for the control and monitoring of indoor air quality (IAQ).

The Model 7515 is an economic instrument to measure carbon dioxide (CO 2). The Models 7525 and 7545 simultaneously measure and record several parameters. The Model 7525 measures CO2, temperature, humidity, and calculates dew point temperature, wet bulb and the% outside air. The Model 7545 also measures the carbon monoxide (CO).

Applications

Measure indoor air quality
Performance monitoring of ventilation systems and air conditioning (HVAC) systems in buildings
Analyzes the conditions of air quality in buildings to maximize employee productivity
Compliance with regulations and standards

Features and Benefits - All models

CO ₂ sensor NDIR low drift for stable and accurate measurements
The sampling function records several measuring points
Ergonomically designed carrying case and molded

7525 and 7545 models

Measuring temperature and relative humidity to determine the thermal comfort
Calculation of% outside air from the CO 2 or the temperature
Dew point and wet bulb temperatures directly calculated
