Non-dispersive infrared (NDIR) absorption

Temperature Sensor

Range

0° to 50°C (32° to 122°F)

Accuracy

±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F)

Resolution

0.024°C at 25°C (0.04°F at 77°F)

Drift

<0.1°C (0.18°F) per year

RH Sensor

Range

1% to 90% RH (non-condensing)

Accuracy

±2% from 20% to 80% typical to a maximum of ±4.5% including hysteresis at 25°C (77°F); below 20% and above 80% ±6% typical

Resolution

0.01%

Drift

<1% per year typical

Response Time

Temperature

12minutes to 90% in airflow of 1 m/s (2.2 mph)

RH

1 minute to 90% in airflow of 1 m/s (2.2 mph)

CO2

1 minute to 90% in airflow of 1 m/s (2.2 mph)

Logger

Radio Power

1 mW (0 dBm)

Transmission Range

Approximately 30.5 m (100 ft) line-of-sight

Wireless Data Standard

Bluetooth Smart (Bluetooth Low Energy, Bluetooth 4.0)

Logger Operating Range

0° to 50°C (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 (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 HOBOconnect use, battery life can be reduced by remaining connected, excessive readouts, checking of Full Status Details, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life.

Memory

128 KB (84,650 measurements, maximum)

Download Type

USB 2.0 interface or via Bluetooth Smart

Full Memory Download Time

20 seconds via USB; approximately 60 seconds via Bluetooth Smart, may take longer the further the device is from the logger

LCD

LCD is visible from 0° to 50°C (32° to 122°F); the LCD may react slowly or go blank in temperatures outside this range
