Features:
- 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
