| Drift | <0.1°C per year (0.18°F per year) |
| Range | 1% to 90% RH (non-condensing) |
|---|---|
| Accuracy | ±2% from 20% to 80% typical Maximum ±4.5% including hysteresis at 25°C (77°F) Below 20% and above 80% ±6% typical |
| Resolution | 0.01% RH |
| Drift | <1% per year typical |
| Range | 0 to 5,000 ppm |
|---|---|
| Accuracy | ±50 ppm ±5% of reading at 25°C (77°F), less than 90% RH (non-condensing) and 1,013 mbar |
| Warm-up Time | 15 seconds |
| Calibration | Auto or manual to 400 ppm |
| Non-linearity | <1% of FS |
| Pressure Dependence | 0.13% of reading per mm Hg (corrected via user input for elevation/altitude) |
| Operating Pressure Range | 950 to 1,050 mbar use (Altitude Compensation for outside of this range) |
| Compensated Pressure Range | -305 to 5,486 m / -1,000 to 18,000 ft |
| Sensing Method | Non-dispersive infrared (NDIR) absorption |
| Temperature | 12 minutes to 90% (airflow 1 m/s atau 2.2 mph) |
|---|---|
| RH | 1 minute to 90% (airflow 1 m/s atau 2.2 mph) |
| CO₂ | 1 minute to 90% (airflow 1 m/s atau 2.2 mph) |
| Radio Power | 1 mW (0 dBm) |
|---|---|
| Transmission Range | Approximately 30.5 m / 100 ft (line-of-sight) |
| Wireless Standard | Bluetooth Low Energy (Bluetooth Smart) |
| Operating Range | 0° to 50°C; 0 to 95% RH (non-condensing) 32° to 122°F; 0 to 95% RH (non-condensing) |
| Logging Rate | 1 second to 18 hours |
| Logging Modes | Fixed interval (normal, statistics) or burst |
| Memory Modes | Wrap when full or stop when full |
| Start Modes | Immediate, push button, date & time, or next interval |
| Stop Modes | When memory full, push button, date & time, or after set logging period |
| Time Accuracy | ±1 minute per month at 25°C (77°F) |
| Power Source | 4 AA 1.5 V batteries or USB power source (5 V DC, 2 Watts) |
| Battery Life | 6 months, typical with logging and sampling intervals of 5 minutes or slower; 6 months or less with logging and sampling intervals faster than 5 minutes while logging CO2. Entering burst logging mode will impact battery life. With app use, battery life can be reduced by remaining connected, excessive readouts, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life. |
