The LaMotte 4331-H Biguanide Plus Borate WaterLink Spin Disk tests for 8 factors in 60 seconds. Each single-use disk contains dried reagents to test for pH, Alkalinity, Calcium Hardness, Copper, Iron, Borate, Biguanide and Biguanide Shock. Disks are individually foil-pouched and packed 50 per box.
Each disk includes a set of reagents for the series. Tests for all factors in the series are performed at one time. It is not possible to isolate the well for a single factor and perform a test for one test factor only.
Note: the disk must be kept flat between tests and all tests on the disk must be run on the same day once it has had water added to it.
