Onset’s HOBO MX1102 CO2 logger makes it more convenient than ever to measure and record CO2 in buildings and other non-condensing environments. It measures CO2 from 0 – 5,000 parts per million (ppm) – and our free HOBOmobile app* allows you to access data right from your mobile phone or tablet within a 100-foot range.

The MX1102 also features a USB port so it can be used with a computer running HOBOware graphing and analysis software. 

 

Features :

  • Wireless communication via Bluetooth Smart
  • Six month battery life at 5-minute CO2 logging rate
  • Easy to deploy and offload using free HOBOmobile App
  • Visual and audible high & low alarm thresholds
  • Self-calibrating CO2 sensor technology ensures optimal accuracy at lower maintenance costs

CO2 Sensor

Range

0 to 5,000 ppm

Accuracy

±50 ppm ±5% of reading at 25°C (77°F) 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

 

Response Time

Temperature

12 minutes 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 HOBOmobile 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.
