HOBO MX1102 Logger

Bluetooth Smart-enabled CO2, temperature and relative humidity data logger

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 Pro graphing and
analysis software.
