The air temperature was monitored using three thermocouples.
Water temperature testing procedure.
A druck ptx 1230 water level sensor was used for control purposes during testing.
In the testing procedure two variables were monitored.
Two sets of tests were performed.
When a glass thermometer is used and the testing point can be reached immerse the thermometer in the water until the liquid column in the thermometer stops moving approximately 1 minute or longer if necessary.
The temperature and pressure relief valve tpr valve opens to release pressure buildup in the water heater when the temperature or the pressure get dangerously high preventing a possible explosion.
Procedure for measuring water temperature tie one end of a piece of string securely to the end of the thermometer and the other end to a rubber band.
Mechanic pressurizes the system raising the pressure in the system gradually until the designated test pressure is achieved.
For drinking water analyses performed by laboratory assistants the actual results will be visibly verified by a microbiologist.
Results are checked before reports are issued by the senior or supervising public health microbiologist.
For a pumping well immerse the thermometer in a container with water flowing through until the temperature stabilises.
If you feel heat radiate off of the water it is hot and may burn you.
If you feel no heat the water will either be room temperature or cold.
Subtract the water temperature from the peak temperature and record.

Run at least 3 tests and determine an average value.
Record the peak temperature which will occur in about 20 seconds.
Slip the rubber band around the wrist so that the thermometer is not lost if it is accidentally dropped into the water.
Maintains this test pressure for 10 minutes before inspection.
Cool to 10 c 50 f for source water and groundwater samples recommended for drinking water as well but do not allow samples to freeze holding times holding times are generally very short 8 hours for source water samples 30 hours for drinking water samples 48 hours for coliphage samples.
Deliver samples to the lab the day of.
The water level and the air temperature.
Some water heater experts recommend testing every six months.
Pour the water into the beaker and observe the increase in temperature of the mixture while stirring with the thermometer.
If you want to form a very rough idea of whether water is cold lukewarm or hot first hold your hand above the water.
Ensures that water used for the test is at not less than ambient temperature but in no case less than 70 f.
Do not stick your hand directly into water either in a kitchen or in nature without first holding step 2 dip your elbow in the water.
Step 1 hold your hand near the water.
If the water container is large enough dip one of.
