Does this unit have auto temp. compensation (atc)?

Yes. This unit has Auto Temperature Compensation from 0 to 50˚C

How often should I change the probe?

If damaged or isnt calibrating correctly. Unsure on longevity.

Why does the tdc function change from ppm to ppt? and, how do you read this in ppm? what does 1.25 ppt mean in ppm?

1 ppt (parts per thousand) = 1,000 ppm (parts per million). 1.25ppt would be 1250 ppm.

for weekly use, How frequently does the probe need to be replaced?

As a rule of thumb, we recommend replacing the one after one year of regular use to ensure the best accuracy.
