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.
The TSI IAQ-Calc™ Indoor Air Quality Meter 7525 is a versatile instrument that is useful for a variety of indoor air quality applications. In addition to verifying HVAC system performance and optimizing worker productivity, it can also help to ensure compliance with regulations and guidelines.
The meter comes with a range of useful accessories, including a hard carrying-case, AA alkaline batteries, and an operation and service manual. It also includes a NIST calibration certificate, which is important for ensuring accurate readings.
One of the key features of the IAQ-Calc™ 7525 is its low-drift NDIR CO2 sensor, which provides stable and accurate readings over time. It also has a sampling function that allows you to record multiple point measurements.
The ergonomic, overmolded case design makes it comfortable to hold and use for extended periods of time. In addition to measuring CO2 levels, the IAQ-Calc™ 7525 also measures temperature and relative humidity, which can help to determine thermal comfort. It can also calculate percent outside air from either CO2 or temperature and directly calculate dew point and wet bulb temperatures.
The meter can display up to three parameters simultaneously, which makes it easy to monitor multiple readings at once. It also comes with LogDat2™ Downloading Software and a USB cable, as well as an AC adapter, which allows you to use it for extended periods of time without worrying about battery life.
