Combined nitrate-selective electrode with polymer membrane.
This ISE is suitable for:
- ion measurements of NO3- (7*10-6 to 1 mol/L) in aqueous solutions
- titrations in aqueous solutions
Thanks to a robust/break-proof plastic shaft made of propylene and an impact protection for the polymer membrane, this sensor is mechanically very resistant.
The reference electrolyte used is c(KCl) = 3 mol/L.
