Simple, quick and portable method for accurate measurements of free and total chlorine - with USEPA approval.
Steadichlor tablets offer a simple and effective means of water chlorination without the need for complex dosing equipment. Steadichlor tablets dissolve in water to give a slow steady chlorine release. The dissolving time is approximately four hours in flowing water or 12-24 hours in static water. Steadichlor tablets are prepared from calcium hypochlorite. In use, the tablets do not contribute any substances not normally present in treated mains water.

The dosage of Steadichlor tablets should, therefore, be controlled in response to free chlorine test readings taken on the treated water. Testing should be carried out using Palintest DPD 1 tablets and a chlorine test kit. Details of the Palintest DPD test and full range of test kits available are available on this website (products menu - browse by parameter - select chlorine), and relevant products are listed below.
