Our Equipment Water Quality Monitors Dissolved Oxygen
Optical luminescent devices which are extremely resistant to abrasion, extremely stable, and have greatly reduced maintenance and whole life costs.
The ORAKEL Dissolved Oxygen sensor has no chemicals or moving parts. It is stable and reliable making it excellent for process controls and is suitable for all Dissolved Ovygen applications.
The ORAKEL range of online Dissolved Oxygen (DO) meters are optical luminescent devices which are extremely resistant to abrasion, extremely stable, and have greatly reduced maintenance and whole life costs.
The sensing element (lumiphore) is activated, or excited when illuminated with a blue light. When activated, the lumiphore then emits blue light in an intensity that is inversely proportional to the amount of oxygen present in the water.
The ORAKEL System offers automatic in situ sensor verification as an option. The Control Unit is able to reduce maintenance by automatically checking it’s sensor operation at user defined time intervals. Calibration on the In Situ sensor is normally required only once per annum so with the automatic sensor verification option and the self clean option the sensor may not need to be inspected at all for years!
The ORAKEL Dissolved Oxygen sensor includes a time delay between the peak emission of blue light and peak response of fluoresced red light. The amount of delay is inversely proportional to the amount of oxygen present. This time delay can be expressed as a phase shift between the wave patterns of incident blue light and the fluoresced red light. This is in turn reported by the electronics into a ppm or mg/l reading of Dissolved Oxygen.
For aeration lane blower control and oxidation ditch dissolved oxygen control, the ORAKEL Dissolved Oxygen sensor offers unrivalled performance.
Two sensors are available:
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 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.
Particle counters are known for their ability to detect when a filter is reaching the end of its life. ORAKEL Particle Counters are sophisticated instruments suitable for municipal and industrial water treatment applications including filter performance monitoring, protecting RO membranes from colloidal fouling and corrosion product monitoring.
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 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.
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.
