HTH DPD3 tablets for combined chlorine

DPD3 tablets measure the level of combined chlorine (chloramines) in your spa or pool water.

DPD3 tablets are more commonly used to measure total chlorine, i.e. all the chlorines (free and combined) in your pool, by combining them with DPD1 tablets.

These tablets are compatible with our test kits, as well as many others.
