DESCRIPTION

The Fluke 975 AirMeter is a comprehensive air quality measurement instrument designed for HVAC technicians and indoor air quality professionals. It simultaneously measures temperature (-20°C to 50°C with ±0.5°C to ±1.1°C accuracy), relative humidity (10% to 90% RH with ±2% accuracy), air velocity (50 to 3000 fpm with ±4% accuracy), carbon monoxide (0 to 500 ppm with ±5% or ±3 ppm accuracy), and carbon dioxide (0 to 5000 ppm with 2.75% + 75 ppm accuracy). The instrument also calculates derived parameters including dew point temperature, wet bulb temperature, volume flow rate in ducts (0 to 140,000 cfm), and percentage of outside air based on temperature or CO2 levels. With data logging capability for 25,000 continuous records, multi-language interface support, and rechargeable Li-Ion battery with AA backup, the 975 AirMeter is ideal for comprehensive HVAC diagnostics, indoor air quality assessments, and building commissioning applications.
