Monitoring and cleaning of exchange units

The exchange unit needs appropriate care.

The 806 Exchange Unit is a versatile buret unit which can be operated with various Metrohm dosing devices or titrators. The 806 Exchange Unit is suitable for simple dosings or titrations. Specifications concerning the exchange unit and the reagent can be stored in the integrated data chip. This data can be read out and updated by a suitable instrument.

Exchange units must be monitored regularly and cleaned from time to time.

Monthly inspections are called for when alkaline, corrosive or high-concentration reagents are used. If non-problematic reagents are used, then the inspection intervals can be extended to several months.
