New De-Chlorination Analyzer

DC80 De-Chlorination Analyzer from Electro-Chemical Devices (ECD), Utilizes a Zero-shift Method to Ensure Stable and Reliable Chlorine Measurement

Municipal water system and industrial process engineers in search of an analyzer that accurately measures near zero levels of chlorine will want to learn more about the plug-n-play DC80 De-Chlorination Analyzer from Electro-Chemical Devices (ECD), which utilizes a zero-shift method to ensure stable and reliable chlorine measurement.

Conventional amperometric chlorine sensors are unstable when measuring near zero amounts of chlorine, which can lead to inaccurate and inconsistent readings. The DC80 De-Chlorination Analyzer utilizes a "zero-shift" methodology to provide accurate measurement and to protect total chlorine sensors from damage, which naturally occurs when the water samples measured contains near zero or zero levels of chlorine.

For example in wastewater treatment when monitoring for chlorine just before outfall, there can be no chlorine present and yet measurement is still necessary. If there is no chlorine present then the electrode becomes unstable and finally unresponsive. Therefore the very process of measuring de-chlorination becomes problematic. If all of the chlorine is removed then the sensor will provide an inaccurate reading after a few hours and fail after a few days still reporting zero chlorine

The DC80 De-Chlorination Analyzer solves this problem: It is a total chlorine analyzer that uses the "zero shift" strategy to monitor near zero amounts of total chlorine. Chlorine is metered into the sample shifting the zero from a near zero chlorine concentration to a measurable value. The analyzer's offset feature allows the metered value to be subtracted from the measurement.

The DC-80 De-Chlorination Analyzer monitors chlorine in drinking water, wastewater, cooling water and other de-chlorination applications from 0.05 - 20 ppm. Its mounted system includes built-in flow control, which eliminates the need for complicated plug-and-play design installs quickly right out of the box. The DC80's advanced panel pressure regulators and rotometers. Built-in automatic pH compensation for samples between 4 and 12 pH also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.
