Technical background:
The philosophy behind NeuLog‟s plug and play technology is based on each sensor‟s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (
o
C,
o
F, Lux, %, ppm, for example).
The sensor needs to be calibrated prior to initial use, please review the “Sensor
Calibration” guide in the beginning of this document for detailed instructions.
Inside the probe a small incandescent light bulb emits infrared radiation which
interacts and is absorbed by carbon dioxide molecules. An infrared sensor detects
how much infrared radiation was not affected by carbon dioxide molecules and in turn
will heat up from the radiation it is collecting. This heat produced is inversely related
to the amount of carbon dioxide present. More carbon dioxide present will produce
less heat and vice versa. The heat acts as a resistor in the wires and based on how
much electrical resistance there is a carbon dioxide reading can be determined
through calculation.
Maintenance and storage:
Never submerge the NeuLog sensor‟s plastic body in any liquid.
Do not allow liquid into the NeuLog sensor‟s plastic body.
After using the probe wipe off all excess material, liquid or residue from the
CO
2
probe body.
Store in a box at room temperature out of direct sunlight.
Do not put the plastic case, or cord of the CO
2
probe in an acids or bases.
Warranty:
We promise to deliver our sensor free of defects in materials and workmanship for a
period of 3 years from the date of purchase. Our warranty does not cover damage of
the product caused by improper use, abuse, or incorrect storage. Sensors with a shelf
life such as ion selective proves have a warranty of 1 year. Should you need to act
upon the warranty please contact your distributor. Your sensor will be repaired or
replaced.
Thank you for using NeuLog!
Flexible, simple, fast, forward thinking.
