Objective : Checking EC and TDS of water samples
Requirements : EC TDS meter , Water samples
Total Dissolved Solids (TDS) and Electrical Conductivity (EC) are two separate parameters. TDS, in layman’s terms, is the combined total of solids dissolved in water. EC is the ability of something to conduct electricity (in this case, water’s ability to conduct electricity).
Preparation :
Take a EC TDS meter and put in water sample and note the Reading .
| sample | EC ( us/cm ) | TDS ( ppm ) |
| Polyhouse Water | 932 | 442 |
| Kitchen | 472 | 226 |
| Dreamhouse | 505 | 236 |
| Regular | 474 | 227 |
| Azolla bed | 706 | 350 |
| Filtered | 521 | 245 |
| Regular Water + Soil | 464 | 218 |
