Product model: FOH900
System Overview
The FOH900 Free alkali on-line analyzer for water quality is widely used to measure free alkali in industrial sewage, industrial boiler water, circulating water and drinking water. The instrument uses continuous flow analysis technology to complete the automatic sample sampling and automatic analysis, and measures the optical signal changes in the mixing process of the sample and titrant through the automatic titration technology to complete the automatic analysis of free alkali, and finally calculates the free alkali value of the actual water sample by comparing with the standard known alkalinity of the substance.
System Features
· Automatic unattended online monitoring of free alkali in water quality;
· The water sample pretreatment device adopts maintenance-free design, which can ensure that the maintenance cycle of the pretreatment device exceeds half a year;
· The measurement process and results can meet the relevant industry standards;
· Microsampling technology ensures low consumption of reagents;
· All imported devices and innovative analysis flow path design ensure measurement repeatability and accuracy;
· Automatic operation, no personnel on duty, can achieve automatic zero, automatic calibration, automatic measurement, automatic cleaning, automatic maintenance, self-protection, automatic recovery and other intelligent functions;
· Diversified online analysis methods can realize manual measurement at any time, automatic timing measurement, automatic periodic measurement and other measurement methods.
