NeuLog NUL-206 Manual

NeuLog pH logger sensor
NUL-206
The NeuLog pH sensor can be used for any science experiment where pH readings
are required. It is used in the fields of Chemistry, Pharmacology, 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.
Among hundreds of possible experiments that can be performed with the NUL-206
sensor are: monitoring of ecological systems, effect of pH on enzymes, static pH
measurements, chemical reactions with changing pH such as titrations, waste
measurements, water testing, etc.
The unit of measurement for this sensor is the pH scale.
pH: The universal measurement for pH which directly measures the concentration of
hydrogen ions using a scale of 0 to 14. Since pH is a logarithmic scale, a difference of
one pH unit is equivalent to a tenfold difference in hydrogen ion concentration.

Sensor offset:

Although the NeuLog pH sensor does not need to be calibrated prior to each use, it is
recommended to offset its probe.
Materials Needed:

pH 7 Buffer Solution (for qualitative measurements, distilled or even tap water
can be used instead)
Procedure:
1. Connect the pH sensor to a voltage source (USB-200 or BAT-200).
Remove the pH sensor probe's tip from the plastic storage solution bottle.
2.
Rinse the pH sensor's tip with distilled water.
3.
Insert the pH sensor's tip into a pH 7 buffer; if no buffer is available, you can use
4.
tap water instead (although it is not as accurate).
Press and hold the pH sensor's push button for 3 seconds.

NEULOG PH LOGGER SENSOR GUIDE
Quick start procedure:
PC or Mac Computer
Materials needed:

NUL-206 pH sensor

USB-200 USB module

USB to mini USB cable (included with the USB-200 module)
Your pH sensor needs to be connected to a USB-200 module. The USB-200 module
then connects to a computer via a USB to mini-USB cable. Please note that you
cannot plug the pH sensor directly into the computer.
The browser based application can be downloaded for free at
well as a full application user guide.
Choose "Downloads" on the main menu and then choose "Software and Application".
Procedure:
1. Install the NeuLog application.
2. Connect the USB-200 module to the PC or Mac.
3. Connect the pH sensor to the USB-200 module (they directly plug together).
Please note that no calibration is required for this sensor.
4. Open the NeuLog application by clicking on the shortcut on the screen.
5. Once the pH sensor module box appears on the left side of the screen, the
probe has been automatically identified and you can begin experimentation.
6. If the pH sensor is not automatically identified, click the "Search for sensors"
icon to find the sensor.
Click on the "On-line experiment" icon; this will open a graph below.
7.
Click on the "Module setup" button located in the pH sensor's module box to
8.
change the sensor's settings if need be.
9. Remove the pH sensor's probe from the plastic storage solution bottle.
Gently rinse the tip of the pH sensor's probe thoroughly with distilled water. Be
10.
careful not to touch the glass bulb.
11. Prior to initial use, the NeuLog pH sensor needs to be offset; please review the
"Sensor Offset" section above.
12. Click on the "Experiment setup" icon to change the experiment settings if need
be (experiment duration for example).
13. The pH sensor will give a live reading in its module box while plugged in.
To run an experiment and collect data, click the "Run experiment" icon.
14.
To end data collection early, click the "Stop experiment" icon.
