1)what is the relation of total dissolved solid and conductivity of water?
2)What is the difference of the conductivity of treated water and raw water?

Wattmeters are used for the measurement of dielectric power loss. It is also useful for the calibration of commercial forms of wattmeter and watt-hour meter in laboratories.

Any fluid contains some solid in it which is dissolved in the fluid. the flow of current in the fluid is due to that dissolved solids. here the relation between electrical conductivity and total dissolved solids (TDS). so Tds meter works on the principle of electrical conductivity by measuring the electrical conductivity and relating it to the dissolved solids the TDS of any fluid can be determined.

TDS meter
this is good to know that there is a way i can find somthing usuful for mi studies
You can purchase a TDS PH meter at most swimming pool supply stores as well as any store that deals with any sort of caustic chemicals that require PH balancing.
trivector meters are used to measure kVAh and also kVA of maximum demand.it has a kwh meter and reactive kvah meter in a case with special summator mounted between them.
To test a calibrate TDS meter has a few steps. First lightly tap or stir the meter that will remove any air bubbles, wait ten to twenty seconds and read the stabilize, for more accuracy readings turn the meter off the meter after each reading and shake off all the water after every use.
