What instrument is used to measure TSS (Total Suspended Solids) in water?

✅Explanation:
The correct answer is Refractometer. TSS refers to the dry weight of particles suspended in a water sample that are not dissolved. A refractometer works by measuring the refractive index of the water sample. The refractive index is a property of a material that affects how light bends as it passes through. The presence of suspended solids slightly alters the refractive index of water compared to pure water. By calibrating the refractometer for a specific relationship between refractive index and TSS, it can estimate the amount of suspended solids in the water sample.

📌Other Options:
-Salometer: A salometer measures the salinity or salt concentration of a liquid, not the total suspended solids. While salinity can contribute to TSS, it's not the only factor.
-Penetrometer: This instrument measures the firmness or penetration resistance of a substance, often used in fruits or soil studies. It wouldn't be suitable for measuring TSS in water.
-Tenderometer: Similar to a penetrometer, a tenderometer measures the tenderness of a product, typically fruits or vegetables. It's not applicable to measuring TSS in water.
