ORDERING AND UPGRADE INFORMATION 

As of Aug 1, 2020, all newly purchased quick-connect DTS-12 turbidity sensors (DTS-12) will 
ship with the V2 DTS-12 end cap and will require V2 cables.  There is no impact to previously 
purchased DTS-12 turbidity sensors (DTS-12) as these can be updated with a new endcap 
for use with the new cables. This product improvement is specific to the quick-connect 
version of the DTS-12.  A DTS-12 with a fixed cable will not be affected by this change. 

B.1

 

Upgrade Path 

Customers looking to purchase a new cable for previously purchased turbidity sensors will 
require a V2 end cap and V2 quick-connect cable. Please order a cable and end cap bundle 
from Table 1, row 3. FTS recommends returning the DTS-12 to our service department for 
end cap installation and to ensure valid warranty coverage as per FTS Service Warranty 
Terms and Conditions. If ordering a new cable length for a DTS-12 with the V2 end cap 
already installed, select a part number from Table 1, row 2 (these are cable only and do not 
include the end cap). It is not necessary to return DTS-12 turbidity sensors with a V2 end cap 
to FTS, swapping of the cable can be done on site. 

Further details can be found in Product Bulletin ISO-PR-B-08 “Re-designed DTS-12 quick-
connect cable / end cap” dated 10 April,2020. 

 

If you have questions, please contact your sales representative or the FTS Service team at
