This is a fully Water Proof Unit
EC Meter : EC stands for Electrical Conductivity, or the ability of a solution to conduct electricity. Electricity moves efficiently through water with high levels of salt present (high EC), and less efficiently with low levels (low EC). EC indicates how much dissolved salt is in a given sample. That is why EC is also referred to as TDS (Total Dissolved Salts) or Salinity (the amount of salts in a solution). All nutrients are salts, so EC is the same as measuring total nutrients in a solution..
Accuracy: ± 2%F.S
Battery Life: Approx. 2yrs
Temperature: 0 - 80C (32-176F)
- If measurement is made in a cup. Be sure to leave a 1/4 inch or 1cm gap between the bottom
- Dip tester into sample solution up to the immersion level.shake to remove bubbles.
- Stir gently and wait until the display stabilizes. Reading are automatically compensated for temperature variations
- Press the"HOLD" key, the reading is being kept, when repeat measuring, please press the "HOLD" key again, It automatically relieves the hold condition
After use, turn the tester off by pressing the "ON/OFF" button,use the water clean the probes and replace the protective cap.
