TSI Incorporated 7525

TSIs IAQ-Calc™ Indoor Air Quality Meter 7525 is an outstanding instrument for investigating and monitoring indoor air quality (IAQ). Model 7525 simultaneously measures and data logs multiple parameters such as carbon dioxcide (CO2), temperature, and humidity, and calculates dew point, wet bulb temperature, and % outside air. 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 > Each Unit Includes Instrument Hard carrying-case (4) AA alkaline batteries Operation and service manual NIST calibration certificate LogDat2™ Downloading Software with USB cable AC adaptor
