Conductivity Sensor for Saltwater Pool K1.0 or K0.1 - which one is suitable?

Hello,

I would like to use the conductivity sensor from Atlas Sientific for our salt water pool. Here there are several types K1.0, K0.1, K10.
I ask myself the question, which one is suitable for a pool. Is it possible to answer this in general?
Do I take the sensor K1.0? This has a measuring range of 5-200,000 µm/cm.
Or is the K0.1 more suitable? This has a measuring range of 0.07-50.000 µS/cm.

I have found the following there:
Source with Description

Relationship between salt concentration in %, g/l (ppt) and mS/cm.
Example:
In the simplest case, the salt concentration is expressed in g/l (ppt) or in percent.
(1 % corresponds to 10 g/l). Further common is the indication in per mil (1 ‰ corresponds to 1 g/l).
0.4 % = 4 kg/m³ = 4 g/l (ppt) = approx. 8 mS/cm

→ thus the sensor K0.1 is the choice!

Please confirm. Thank you!
Kind regards

If that’s not the one, can you provide a link?

It seems suitable for salt water, though you don’t want the electronics left exposed.
