Measurements of water quality of the various types of water, and now I will discuss water quality analysis of only one type of water, the river water quality analysis, in which many parameters that must be contained inside the known results and the data must be accurate to take water samples from river required the preparation of preparation before going broad, including measuring equipment and chemical substances such as1. pH meter to measure the acid content and water alkalis
2. Thermometer for measuring water temperature
3. Conductivity meter for measuring electric power flow
4. DO meter or dissolved Oxygen meter to measure the oxygen content in water, and also to measure the BOD or biological oxygen demand known as biological oxygen demand
5. Kits for analysis of bacteria such as faecal coli, and the total coli etc.
