New residual chlorine monitor offers
cost savings
Analytical Technology has introduced the Q45H chlorine monitoring system for the on-line monitoring and control of chlorination in water
Analytical Technology has introduced the Q45H Chlorine monitoring system for the on-line monitoring and control of chlorination in water The water industry has historically relied on open cell amperometric monitors with buffer delivery systems for examining the levels of chlorine in the disinfection process

Analytical Technology (ATi) announces the launch of its innovative new Q45H/64 Dissolved Ozone Analyser for reliable on-line monitoring and control of ozonation systems.
Monitor achieves precise free chlorine measurement
The Analytical Technology Q45H chlorine monitoring system achieves accurate and reliable free chlorine measurement even in the presence of high levels of un-dissolved iron and manganese salts
It is estimated that the cost to the UK water industry of operating an amperometric monitor with buffer could exceed GBP20 million per year.
The high costs and other factors, including environmental impact and health and safety issues, have caused the water industry to look for alternatives to liquid buffers.
Some companies have chosen to use carbon dioxide as a less expensive greener alternative to liquid buffers.

Analytical Technology has introduced the innovative ATi Q45H/65 Residual Chlorine Dioxide monitor for the on-line monitoring and control of industrial disinfection systems
Many companies are now using or looking to use totally reagent free monitors.
Most manufacturers now offer reagent free chlorine monitors.
The key advantage of the new Q45H is that it utilises an innovative enhanced pH response membrane-covered polarographic sensor that does not require the addition of chemical reagents.
The ATi sensor has a response around 10 times higher than that of conventional sensors at high pH values (pH 8.3).
This means that the monitor can be used at reagent free over all the pH values found in the UK water drinking industry.
By also eliminating the need for costly buffer reagents, the Q45H provides an extremely cost-effective and environmentally-friendly alternative to conventional chlorine monitors.
The Q45H eliminates the problems of storing, handling and disposing of chemical reagents, minimising the total running cost of the monitor.
The new Q45H is capable of measuring both chlorine and pH simultaneously with 4-20mA outputs for both parameters.
A flexible range capability allows monitors to be programmed for display ranges of 0-2, 0-20 or 0-200 PPM with analogue outputs scalable within the display range to any desired value.
For low-level applications, a display range of 0-200 PPB may also be selected.
Mike Strahand, General Manager Europe at ATi, comments: "The introduction of pH corrected membrane monitors offers the water industry a new way forward.
The Q45H means no more costly reagents to purchase, handle and store with no compromise on application ranges.
Instead all that is now needed is a constant flow of water across the face of the sensor, provided by an easy to install simple constant-head flowcell".
