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.
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?

Q-meter works on the principle of Series Resonance
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.
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.
basic principle of analogue clamp meter
CLAMP METER WORKS WITH THE PRINCIPLE OF HALL EFFECT..
With a TDS meter...your local pool supply store can do this for you.
TDS is an abbreviation in the transportation industry when freight charges are assessed. TDS means Transport Deductor Service. This means that the transporter of the freight is required to have certain credentials that meet the laws of both countries involved when shipment occurs overseas.
There is a basic conversion factor of 3 to 1 (# NTUs x 3 = #mg/L).
