Question by Anon: How can you measure the salt content in mud?
I need to figure out a way to measure the amount of salt in mud in order to determine the conditions that mangroves grow best in. Any ideas?

Best answer:

Answer by carbonates
Measure the conductivity, or its inverse, resistivity.

“Total Dissolved Solids (T.D.S.) expressed as mg/L: Conductivity is measured in mA as the intensity of the current passing between two electrodes submerged in 2 mL of the sample and connected to a 9 V DC source. The millimeter range is kept as 20 ma Two paper clip steel wires are used as electrodes.

Calculations:
Conductivity of Baraka (reference sample containing 440 mg T.D.S./L) sample = 2.7 ma
mg T.D.S / L / ma = 440/2.7 = 163
T.D.S. of any sample in mg/L = Conductivity in ma x 163”

Here is an example from an aquarium application:

Measuring conductivity/resistivity is a common tool used in the industry to help identify the type of rock that surrounds a borehole. The measurement problem is very similar to yours, as there is drilling mud, shale, and salt water involved.

Many conductivity meters actually measure total dissolved solids, which is probably the answer you are looking for.

    Good quality, but the black doesn’t help., January 7, 2014

    I work in the bakken , a lot of our is a clear to orange “sweet crude”. This really doesn’t help, unless you’re working nights and using the black light. Worthless for salt water. Numbers are huge and easy to read, build quality is good /same as the other atlas tapes. Line wiper fits with no problems….. It does work well with dark oils but that’s less 5% of the holes I flow.
