Specified resistivity – (≤10 ohms/sq) or (~7ohms/sq) or (~15 ohms/sq) Typical resistivity – (9-11 ohms/sq) or (7- 8 ohms/sq) or (12 – 15 ohms/sq) The transmittance at 550nm – ≥ 79% FTO film Thickness – (1800-2000 Å) or (1400-1500 Å)...
These work on the principle of difference in reflective indices of liquid in the tank and possible presence of gas with the liquid. The liquid will be black display while the gas or vapor will be white display....
