PROCEDUREPH TEST1. Three (3) different sample of water was prepared which sample water 1, sample water 2 and tap water.2. The samples are filled into three (3) different beakers.3. Take one of sample and test by using pH meter.4. The pH value and temperature of sample is recorded.5. Repeat step 3 and 4 by using sample water 2 and tap water.

TURBIDITY TEST1. Same samples are used for this test.2. Take one of sample and filled into small glass tube and insert into the turbidity meter. Make sure the glass tube was clean from any finger tips.3. The turbidity value of water is recorded.4. Repeat steps 2 and 3 by replace the sample to sample water2 and tap water.

CONDUCTIVITY TEST1. By using same sample, take one sample and dip in a rod into the beaker.2. The rod is connected to the conductivity meter.3. The value and temperature of conductivity is recorded.4. Repeat steps 1-3 by using sample water 2 and tap water.1
