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.
