1. Scientific Tools for Water Quality Testing

2. We will conduct: Nine basic tests D.O. or dissolved oxygen pH
Temperatures of water and air
Conductivity
Phosphates
Nitrates
Turbidity
Total dissolved solids, or TDS

3. There are certain tools you must become familiar with
Things such as glassware, pipettes, timers, probes, LabQuest handheld units, infrared thermometers (IRTs), test tubes, droppers, octets, and goggles, to name a few.
The following pictures will show you what these tools look like. You will have opportunity to check them out and learn how to use them properly and safely. These are NOT toys and should be handled respectfully.

4. glassware
These are examples of glassware. They each have a different name.
Erlenmeyer flask
beakers
Test tube
Volumetric flask
Graduated cylinder

5. Technology field tools
Examples are:
This is a LabQuest hand held unit
This is a probe used with the LabQuest
This one is a temperature probe.
It will read the temperature anywhere
it is placed.

6. Other field technology tools
Examples are:
This is a non contact infrared thermometer
Also called an IRT, we use it to measure
the temperatures of things we cannot
touch or get close to. It can measure
temperatures up to 45 miles away
in either F or C instantly. You must
not handle it until you actually take
the temperature because your hand can
influence the reading.

7. Here are some other tools we will use:
pipettes
Simple test kit with tablets
Safety goggles
Checking titration against the chart

8. Chemical Test kits
We will use these to test for things we cannot find out by using a probe.
