LaMotteSpinTouch Reagent Disks Cl/Br/pH 3-Way Disks, 4334-H.

This is the 4334-H disks. 50 disks that have 3 tests per disk. Negative reviews on this item so far but I received exactly what I ordered well packaged in a timely fashion. Lamotte has a chart of all the different disks, and what they will test for. Look at that and then buy the part number you desire.

False advertising in this sellers title. I needed the three test series disks for alkalinity, pH, and total/free chlorine. Instead I received disks that only test for total chlorine, free chlorine, and pH. These disks DO NOT test for alkalinity whatsoever. Not what I needed unfortunately.

Ordered 2 boxes of disks. Got 4 disks. Over 300.00.
