NEULOG CONDUCTIVITY FIELD SENSOR GUIDE
NeuLog conductivity sensor
NUL-215 Carolina # 369644
The NeuLog Conductivity Sensor can be used for any science experiment or activity
which utilizes liquid samples that can conduct electrical currents such as in the fields
of Chemistry, Biology, Earth Science, Environmental Science, Biochemistry, Physics,
etc.
Electrical conductivity is a material property measured by how easily it is able to
conduct electrical currents. A current is the flow of electrical charge (electrons)
through ions in a material. This sensor is designed for detecting electrical currents
specifically with liquid solutions.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using any of the following guides. There are three units in which data can be
collected: μs/cm – micro Siemens per centimeter, mg/L – milli gram per liter, and ppm
– parts per million.
Just a few of the thousands of possible experiments that can be done with the NUL215 sensors are: Monitoring of ecological systems, chemical analysis and
identification, environmental health testing, water quality testing, etc.
Probe usage and care:
The probe has two flat electrodes with known surface areas and distance between
them. A signal is supplied to the electrodes and by testing the signal behavior, the
conductivity of the solution is calculated.
General care:
Avoid touching the probes flat green surface if possible.
Never submerge the probes plastic body in any liquid.
Gently rinse the probe off with distilled water after each use and between
samples to avoid damage and contamination.
Handle and store with care to avoid damaging or chipping the probe.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-215 Conductivity Sensor
USB-200 USB Module
A USB to mini USB cable (which comes with the USB-200)
Your conductivity 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 conductivity sensor directly into the computer.
Resident PC software and browser based software can be downloaded for free at
www.NeuLog.com/dowload as well as a full software user guide. Note: Make sure not
to download and install both types of software, they will conflict on the computer.
Procedure:
1. Install the NeuLog software
2. Connect the USB-200 module to the PC or Mac
3. Connect the conductivity sensor to the USB-200 module (they directly plug
together). Please note there is no calibration required for this sensor.
4. Open the NeuLog software.
5. Once a conductivity sensor logo appears on the left side of the screen the
probe has been automatically identified and you can begin experimentation.
6. If the conductivity sensor is not automatically identified then click the
“Search for sensors” icon to find the sensor.
7. Select the “On-line experiment” button; this will open a graph below.
8. Click on the “Module setup” button located on the conductivity sensor icon in
the module window to change the sensor settings if need be.
9. Click on the experiment set up button to change the experiment settings if
need be (experiment duration for example).
10. The conductivity sensor will give a live reading in the box to the left of the
screen while plugged in.
11. To run an experiment and collect data click “Run experiment”.
12. To end data collection early, click “Stop experiment”.

Tablet, smart phone device
Materials needed:
NUL-215 Conductivity Sensor
WIFI-201 WIFI module
BAT-200 Battery
Your conductivity sensor needs to be connected to a WIFI-201 module. The WIFI-201
module will create a closed NeuLog wifi network which will stream the NeuLog data to
a device of your choosing. Once your device is wirelessly connected to the NeuLog
network you can run experiments and collect data through a browser of your choosing.
Procedure:
1. Connect the conductivity sensor directly to the left side of a WIFI-201
module (no wires required).
2. Connect a BAT-200 module to the right side of the WIFI-201 module.
3. Although not required, we recommend plugging the BAT-200 to an outlet
using a USB to micro USB charger (such as a typical cell phone charger).
The WIFI-201 module will run for 15-75 minutes (depending on the sensor)
without being plugged in.
4. For further WIFI-201 instructions or the WIFI-201 quick start guide please
visit www.NeuLog.com/download.
5. The WIFI-201 indicator lights will flash; take no action until the LED to the
far left turns blue.
6. Take your tablet or smart phone and go to the Wi-Fi settings and select the
NeuLog network which matches the WIFI module ID found on the back of
the WIFI-201 device. (NeuLogXXXX for example)
7. Give your device 1-2 minutes to connect to the WIFI-201 network.
8. Once the device is connected go to your browser and type in the website
wifi201.com into the URL bar, then wait for 30-60 seconds.
9. You will see a “Control mode” icon in the browser, click on this icon.
10. The browser will then load a new screen and begin to auto detect the
sensors, this can take a few minutes.
11. If the browser does not auto detect, select “Search for sensors”
12. Once the sensor is found you will see an icon on the left side of the screen
for the conductivity sensor. The icon will display data in real time.
13. To set the conductivity sensor’s settings click on “Module setup” button
located on the conductivity sensor icon on the left side of your screen.
14. To change the experimental settings click the “Experiment setup” button
(experiment duration for example).
15. To run an experiment and collect data click “Run experiment”.
Operation with NeuLog viewer
Materials needed:
NUL-215 Conductivity Sensor
VIEW-101 Viewing Module
BAT-200 Battery
Procedure:
1. Connect the conductivity sensor to the left side of the viewer.
2. Connect the BAT-200 module to the right side of the viewer.
3. The VIEW-101 will auto detect the sensor and you will see it appear on the
left side of the screen.
4. Once the sensor appears it will be monitoring data in real time.
5. To run an experiment and collect data click the run button (little green
person).
Off-line experiments
(Off-line experiments are for when you do not have a sensor connected directly to a
computer, tablet, smartphone, or NeuLog viewer).
Materials needed:
NUL-215 Conductivity Sensor
BAT-200 Battery
