Water Monitoring Testing
Temperature
Temperature is very important to water quality. Temperature affects the amount of dissolved oxygen in the water, the rate of photosynthesis by aquatic plants and the sensitivity of organisms to toxic wastes, parasites and disease. Thermal pollution (e.g., the discharge of heated water from industrial operations) can cause temperature changes that threaten the balance of aquatic systems.
What You'll Need:
- Sample container with your collected water sample.
- Protective gloves.
- Thermometer from your test kit.
Use of the thermometer: The temperature is indicated by a liquid crystal number on the Low Range thermometer and a green display on the High Range thermometer, as shown in the diagram below.

Temperature Test Procedure:
- Take the adhesive back off the thermometer and stick them to something that will make them easier for you to grasp.
- Wear protective gloves. Then, place the thermometer four inches below the water surface of your sample for one minute.
- Remove the thermometer from your sample, read the temperature and record it on your field data sheet as degrees Celsius.
