Overview

The ECD Model CA900 Titration Analyzer provides automated online measurement of Total Alkalinity using a high-precision pH sensor to measure acid-neutralizing capacity and maintain proper pH balance. Designed for quick deployment, the factory pre-calibrated analyzer installs in under 15 minutes by simply connecting the sample, waste, and reagent lines before powering up. It is widely used across municipal drinking water, wastewater treatment, agricultural irrigation, water-based beverages, pharmaceuticals, and electronics manufacturing. The unit comes standard with wall-mounting hardware, and an optional benchtop stand with a reagent holder is also available.
