The 12-Series Calcium Ion-Selective Electrode (ISE) is a premium laboratory or field electrode offering excellent performance and longevity in many water applications such as beverages, milk, aquariums, and water hardness evaluations.

Specifications:

Range: 0.02-40,100 ppm

Sample pH Range: 2-8

Slope: 26 ± 2 mV/ decade

Interferences: Pb2+, Hg2+, Si2+, Fe2+, Cu2+, Ni2+, NH3, Na+, Li+, Tris+, K+, Ba2+, Zn2+, Mg2+

Features:

Refillable reference, replaceable sensor modules and standard 12mm diameter and 120mm length

• The refillable, double-junction reference gives the electrode more longevity over sealed reference designs
• The replaceable sensor modules (PVC matrix sensor type) allow you to periodically replace the sensor, rather than the whole electrode
• Suitable for all general purpose or more advanced applications
