NeuLog CO logger sensor

NUL-220
The CO Sensor can be used for any science experiment or activity where CO
2
are required. Some fields of study include Chemistry, Physiology, Exercise Science,
Biochemistry, Biology, Earth Science, Environmental Science, etc.
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
Just a few of the thousands of possible experiments that can be done with the NUL-
202 sensor are: Monitoring of ecological systems, combustion reactions, CO
consumption rates, studying photosynthesis, testing chemical solutions, hydrogen
peroxide decomposition, and many more.
The NeuLog CO sensor collects data in the following units of measurement:
2

Parts per million (ppm): The total number of carbon dioxide molecules per
million molecules sampled.
Sensor calibration:
Prior to each use the CO needs to warm up for roughly half an hour. To do this, plug
2
the CO sensor into a USB module or a battery pack and allow the sensor to sit for half
2
an hour prior to collecting data for the best results.
Open air mode:
The CO sensor needs to be calibrated before use. Calibration of the probe assumes
2
a standard atmospheric CO concentration of 20.9% (assuming stable levels in the
2
Earth's atmosphere at sea level).

Procedure:
1. The CO sensor needs a power supply to properly calibrate so connect the
2
CO sensor to:

a. For On-line experiments: USB-200 USB Module.
b. For Off-line experiments: BAT-200 Battery
c. For use with the NeuLog Viewer: VIEW-101 Viewing Module
and BAT-200 Battery.
2. The sensor now needs to be calibrated:
a. Connect the CO sensor to the left side of a USB-200 Module

(which is connected to a computer via the USB to mini USB
cable).
b. Open the NeuLog software.

Quick start procedure:
PC or Mac Computer
Materials needed:

NUL-220 CO Sensor
2

USB-200 USB Module

A USB to mini USB cable (which comes with the USB-200)
Prior to initial use the NeuLog CO sensor needs to be calibrated, please review the
2
"Sensor calibration" section of this document on beginning on page 2 for detailed
instructions. Your CO sensor needs to be connected to a USB-200 module. The
2
USB-200 module then connects to a computer via a USB to mini-USB cable. Please
note that you cannot plug the CO sensor directly into the computer.
