A test method developed to easily determine the acid bonding capacity. Any chlorinated solvent will become acidic under work conditions. In order to reduce the acidization, DOWPER™ MC, DOWPER™ N, NEU TRI E, MECTHENE MC solvents are equipped with neutral acid acceptor that provides additional protection. These stabilizators can be consumed during usage. Therefore solvent status shall be regularly checked. Two tests are used for DOWPER™ MC and DOWPER™ N for this purpose:

- pH Value/Alkalinity Determination
- Acid Acceptance Determination

MAXICHECK™ AA TEST KIT was developed to guarantee there is always enough acid bonding capacity.
