Silica, Phosphate, Hydrazine, Ammonia, Copper and Ethylene Glycol Analyzers 7040 Portable Series

REVOLUTIONARY PATENTED TECHNOLOGY

Our Colorimetric Analyzers (Aqualyzer® Series 7040) are based on the new patented Loop Flow Analysis (LFA) cycle.

Common application points in a boiler system for silica measurement include: make-up water, condensate, boiler feedwater, saturated steam/main steam and cooling water. Application points for phosphate include: boiler water and cooling water.

LFA technology involves isolating,manipulating and testing a known volume of sample in a closed loop system. A powerful programmable microprocessor allows for customized program cycles,ensuring accuracy and reliability with every application.
