Home Our Equipment Water Quality Monitors Chlorine
The ORAKEL range of Residual Chlorine Analysers, Residual Chlorine Controllers and Residual Chlorine Monitors are membrane devices which are insensitive to changing pH, use no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs.
The membraned amperometric chlorine sensors are enhanced with a third, reference electrode which eliminates zero drift. Its unique design means that pH correction is not usually required at all, completely eliminating reagents.
In addition to the state of the art potentiostatic chrono-amperometric free chlorine and total chlorine sensors, the ORAKEL range of residual chlorine analysers has all the functionality that you need, and more.
Applications
The ORAKEL chlorine analyser range is particularly suited to working in sites where reliability and ease of use are most important.
Water Treatment applications:
Chlorine sensor options:
The ORAKEL Chlorine sensor can be installed in a variety of auxiliary flow cells and self-cleaning devices.
Water can have a positive or negative Oxidation Reduction Potential (ORP) and it is measured in volts. ORP is a way to measure water’s ability to accept or release electrons during a chemical reaction. Understanding the ORP value helps determine the quality of the water and thereby helps operators decide what water treatment processes may be required. The more positive the ORP value, the greater the tendency the water has to oxidise (gain electrons from) organisms or other material in the water, thereby killing or destroying them.
The ORAKEL System is ideal for all your water monitoring equipment needs, measuring both water flow and water quality at the same time. Created as a modular system, a wide range of water quality sensors can be added to measure various characteristics, such as pH, COD and suspended solids, for a truly bespoke and cost-effective solution.
The pH5 electrode has a double-junction reference to prevent contamination of the reference from sample components.
This design gives the electrode a longer life compared to ordinary electrodes (up to 3 yrs). The electrode also has a hemi-shaped glass measuring surface which is more durable than the traditional bulb-shaped glass.
Sitting at the top end of the market place, the ORAKEL pH probe has a longer life and lower maintenance requirements. Typically it only needs calibrating once every two or three months, making it a very cost effective solution.
The ORAKEL Suspended Solids senor has a large dynamic range, which eliminates the need for a “zero” and also eliminates the effect of background light.
For multiple measuring ranges, the suspended solids sensor can monitor turbidity and suspended solids from 2 NTU (1mg/l) to 8%* solids.
The ORAKEL Turbidity monitor automatically varies the light output so that the turbidity can be measured independently of background light and electronic drift. It is ISO 7027 compliant and covers a range of 0.01-1000 NTU (0.01-2000mg/l depending on the sample).
The ORAKEL System determines true turbidity and/or suspended solids in water, using a nephelometric measurement of scattered light in accordance with ISO 7027. The sensor uses lifetime-based optical technology to provide an extremely stable, accurate, low maintenance sensor with no moving parts and no consumables.
The ORAKEL range of Conductivity meters also double as a Salinity meter and a TDS meter. The range measures conductivity in water from 0 to 2,000,000 µS/cm (range selectable). You can choose between a standard graphite sensor and a more sophisticated toroidal sensor, or stainless steel ‘special’ sensors for high temperature, high pressure conductivity measurement applications.
