Description

With no electrolyte to top-up, the 100 ULTRA reduces the maintenance requirements and costs typically associated with pure water applications. The 100 ULTRA features a high-volume internal chamber containing a super-saturated electrolyte matrix with a large porous PTFE junction that provides added measurement stability with minimal drift for long-term measurement down to 2 μS/cm.

The 100 ULTRA sensor provides:

Increased efficiency

Propriety high performance glassware formulations provide the highest level of reliability and responsiveness
Close-coupled temperature measurement ensures high accuracy even with rapid temperature changes
Maintenance-free and reliable

Saturated KCl matrix offers extended operation in high-purity applications with minimal drift
Large, porous PTFE junction reduces plugging and fouling effects while providing measurement stability
Robust PVDF ¾ inch NPT body provides superior mechanical and chemical resistance
Each electrode is manufactured to the highest quality standards and provided with a calibration certificate
