Combined calcium-selective electrode with polymer membrane.
This ISE is suitable for:
- ion measurements of Ca2+ (5*10-7 to 1 mol/L) in aqueous solutions
- complexometric (back) titrations (e.g., determination of water hardness)
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(NH4NO3) = 1 mol/L.
