EZ3000 Sulfide online analyzer

Measuring method:

Sequential batch direct ion-selective electrode method, compliant with standard method ASTM D4658-15

Instrument features:

• 1) The instrument adopts the sequential batch ion-selective electrode method, which enhances control of the conversion of ion activity to potential while also eliminating the risk of cross-contamination between measurement cycles and reducing overall reagent consumption.

• 2) Intelligent automatic control system

• 3) Multiple measuring ranges available to meet different application needs

• 4) Multiple analog and digital output options

• 5) Supports multi-channel analysis (up to 8 channels optional)
