NeuLog CO logger sensor

NUL-220
The CO Sensor can be used for any science experiment where CO
2
required. Some fields of study include Chemistry, Physiology, Exercise Science,
Biochemistry, Biology, Earth Science, Environmental Science, etc.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using this guide.
This sensor is practical for testing CO levels both in laboratories and in the field. An
2
electromechanical cell in the sensor reacts with carbon dioxide to produce a voltage
which is directly interpreted to give a CO
Among hundreds of possible experiments that can be performed with the NUL-202
sensor are: Monitoring ecological systems, combustion reactions, CO
rates, studying photosynthesis, testing chemical solutions, hydrogen peroxide
decomposition, and many more.
The NeuLog CO sensor's measurement unit is:
2
Parts per million (ppm): The total number of carbon dioxide molecules per million
molecules sampled.
Sensor offset:
Prior to each use, the CO sensor needs to warm up for roughly half an hour. For best
2
results, plug the CO sensor into a USB or battery module and allow it to sit for half an
2
hour before to collecting data.
Open air mode:
Although the NeuLog CO sensor does not need to be calibrated, it is recommended

to offset its probe.
The sensor offsets to the standard atmospheric CO
air (assuming stable levels in the Earth's atmosphere at sea level).

Materials Needed:

NUL-220 CO sensor
2

One of the following (depending on experiment type):
- USB-200 Module (For On-line experiments)
- BAT-200 Battery Module (For Off-line experiments)
- VIEW-101 Graphic Display Module and BAT-200 Battery Module (Optional,
for use with NeuLog Viewer)
Procedure:
1. It is recommended to offset the sensor outside (you can get it out through a
window if it is connected to a USB module).
2. The CO sensor needs a power supply to properly offset. Connect the CO
2
sensor to:
USB-200 module for On-line experiments
-
- BAT-200 battery module for Off-line experiments
- VIEW-101 graphic display module and BAT-200 battery module for use with
the NeuLog Viewer.
3. After the sensor has been connected to a power supply for at least 30 minutes,
check that the values are relatively stable.
4. The sensor now needs to be offset -
hold the probe vertically with the opening facing the ground.
Press and hold the blue "Start/Stop" button on the faceplate of the sensor for 3
5.
seconds.
6. The CO Sensor is now offset for use.
