NEULOG DROP COUNTER LOGGER SENSOR GUIDE
NeuLog drop counter logger sensor
NUL-223
The NeuLog drop counter sensor can be used for any science experiment which
utilizes fluid drip rates, particularly in the fields of Chemistry and Biology.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using this guide.
The NeuLog drop counter sensor excels in the laboratory but can also be used in the
field for a number of experiments in various configurations. For example, titrations
become much more accurate as you can determine both the total number of drops
and the total volume which has passed through the drop counter sensor.
The drop counter sensor's measurement units are:
Drops: The number of times a drop of liquid passes through the drop
counter sensor.
Milliliters (mL): The SI unit of volume. The NeuLog drop counter sensor
calculates the rough volume of drops which pass through it.
Setting up the drop counter sensor:
There are a number of ways to set up the NeuLog drop counter sensor to give
accurate readings. The drop counter gate includes three threaded holes and a
threaded utility rod which can be attached to various lab equipment to offer many
different orientations.
The most important aspect while setting up the drop counter sensor is to ensure that
the drops of liquid are passing through the sensor correctly. As in the figure below,
you will want to orient the sensor so that drops pass through the infrared beam
transmitted between the ends of the drop counter sensor.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-223 Drop Counter Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your drop counter 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 drop counter 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 drop counter 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 a drop counter 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 drop counter sensor is not automatically identified then click the “Search
for sensors” icon to find the sensor.
7.
Select th
e “On-line experiment” icon; this will open a graph below.
8.
Click on the “Module setup” button located in the drop counter sensor module
box to change the sensor settings if need be.
9.
Click on the "Experiment setup" button to change the experiment settings if need
be (experiment duration for example).
10. The drop counter sensor will give a live reading in the module box to the left of
the screen while plugged in.
11.
To run an experiment and collect data click the “Run experiment” icon.
12. To end data collection early,
click the “Stop experiment” icon.
