By using "State of the Art" manufacturing materials and techniques the Elox100 of LAR Process Analysers AG offers performance previously only available from the most expensive on-line analysers.
Using the same LAR measuring principle, the Elox100, designed and built on the worldwide success of the EloxMonitor, offers an economical alternative for on-line COD measurement.
For this, the Elox technique, a worldwide patented electrochemical method has been developed by LAR Process Analysers AG which, by the action of an electrical current on an electrode, produces OH-radicals as the oxidizing agent.
OH-Radicals have a higher oxidation potential than common oxidizing agents (ozone, hydrogen peroxide), and therefore, they will oxidize difficult substances in water rapidly!
The method requires no caustic or other endangering substances. No cleaning solutions or hazardous reagents are required to be used or disposed of. The result is the highest operational safety and outstanding, uncomplicated operation.
Every available software function is screen help supported, in addition to the operation manual which gives information in relation to routine operation and servicing. Data can easily be transferred to disk or via serial or parallel interface to a measuring station for further processing or remote control.
The Elox100 resumes normal operation after power loss and stores all previous data in memory.
The Elox100 is suitable for almost every COD measurement in sewage treatment and industrial applications.
The ranging allows the determination of COD values between 1 and 100,000 mg/l. This extremely wide measuring range fully covers the need for monitoring and process control.
Moreover, an enormous number of users from very different industries and countries have put their trust in the Elox100.
The great advantage of the system is that within 30 seconds of delivering a sample the measured COD value is available.
The sensitive and fast measurement guarantees the successful operation of the Elox100 as a useful measuring instrument in municipal and industrial process control.
The patented sample preparation system FlowSampler works filtration-free as the sample is taken in the centre of the sample stream against the direction of the main flow.
Thereby, all large particles are reliably removed. Smaller solid matter particles will however be sampled, so that a representative sample reaches the analyzer.
FlowSampler masters even the most difficult tasks, for example; sampling at sewage work influents before the coarse screen.
The crucial advantage of the Elox100 is the oxidation of all water components in short time. Different from photometric measurement systems an actual oxidation happens. A falsification of values due to coloration or turbidity (e. g. in chemical industry or paint production) cannot occur.
