Fits indoor air quality surveys where you need an Extech EA80 with maintenance-free dual-wavelength NDIR CO₂ to 6,000 ppm, temperature/humidity, dew point/wet bulb, and 20,000-set logging.
Key advantages
- CO₂ — 0–6,000 ppm; 1 ppm resolution; dual-wavelength NDIR
- T / RH — −4 to 140 °F (−20 to 60 °C); 10–95% RH
- Calculated — Dew point and wet bulb
- Logging — Continuous 20,000 sets or manual 99; RS-232 PC software
- Functions — Hold, Max/Min with timestamp, alarm, fresh-air calibration
Typical applications
- IAQ walkthroughs and audits.
- CO₂ demand-control verification.
- Logged indoor environment studies.
Selection guide
- Logging mode — Continuous vs manual 99
- Calibration — Fresh-air routine
- PC interface — RS-232 software
- Alarms — CO₂ setpoints
Common mistakes
- Skipping fresh-air calibration.
- Using outside 10–95% RH band.
- Expecting outdoor weatherproofing.
