Warm-up Time:
15 seconds
Calibration:
Auto or manual to 400 ppm
<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
Response Time:
Temperature:
12 minutes to 90% in airflow of 1 m/s
12 minutes to 90% in airflow of 2.2 mph
RH:
1 minute to 90% in airflow of 1 m/s
1 minute to 90% in airflow of 2.2 mph
CO2:
1 minute to 90% in airflow of 1 m/s
1 minute to 90% in airflow of 2.2 mph
Logger:
Radio Power:
1 mW
0 dBm
Transmission Range:
Approximately 30.5 m line-of-sight
Approximately 100 ft line-of-sight
Wireless Data Standard:
Bluetooth Low Energy (Bluetooth Smart)
Logger 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 a set logging period
Time Accuracy:
±1 minute per month at 25°C
±1 minute per month at 77°F
Power Source:
4 AA 1.5 Volt batteries (user replaceable) 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.
