Horiba Ionic Strength Adjustors - ISA & TISAB Item:500-CA-ISA - Calcium Ionic Strength Adjustor, 500 mL - 3200697178 PVDF cable

PVDF cable

disposable sampling points

TDS: 0 ppm to 10 ppt

Keep the filling solution level above the sample level so flow is always outward through the junction — this prevents sample being drawn into the reference chamber

and cost-effective for everyday water-quality work

Horiba Ionic Strength Adjustors - ISA & TISAB Item:500-CA-ISA - Calcium Ionic Strength Adjustor, 500 mL - 3200697178 PVDF cableIonic strength adjustors for HORIBA ion selective electrode measurements. An ISA or TISAB in the case of fluoride is added in a fixed proportion to both your standards and your samples so that every solution the electrode sees has the same background ionic strength. Why this reagent is not optional An ion selective electrode does not respond to concentration. It responds to ion activity, which is concentration multiplied by an activity coefficient
