On the back of my TDS meter it says calibrate with NaCI which is salt, correct?
How would I go about calibrating it?

there are calibration solutions available. Just calibrate the meter to the strength of the solution and you should be good to go.
1382 PPM Solution
(for TDS electrodes, 220 ml), CD-870910 from Foster & Smith
Would this work with an Inline digital TDS meter?

As long as there is a way to dunk the sensor into the solution it should work.
For inline meters to be accurate the solution must be moving past the probes, just dunking them is not reliable. They are also not temperature compensated so you must match the temperature too.
