TDS METERS SUITABLE FOR APEX

[SAMS]

Has anybody managed to find an inline TDS meter that can be used with the neptune apex system?

I work for a company that distributes HM Digital & Milwaukee products in the UK, so have access to the products at decent prices.
However I am just trying to find one that can be used with the neptune apex system.

Thanks in advance for any suggestions

Would this model be suitable at all?

As it has a 4-20ma output
