Home Our Equipment Water Quality Monitors
We have an extensive range of water quality monitoring sensors and controllers to measure various water characteristics including pH, turbidity, COD and many more. You can monitor everything from wastewater treatment, to trade effluent discharge, to environmental quality monitoring.
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.
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.
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 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.
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.
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 peracetic acid sensor is a membrane device which use no reagents. It is extremely stable and has a reduced maintenance and reduced whole life costs.
With its reduced maintenance, reduced calibration and reduced spares requirements, the ORAKEL peracetic acid sensor is arguably the most cost effective peracetic acid analyser available.
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 COD/TOC Sensor uses UV254 light as a surrogate measurement for detecting organics in water.
It is designed in modular form so that it can be integrated with other sensors, such as pH, turbidity and dissolved oxygen, to provide all the tools needed for either a stand-alone UV254 analyser or as part of an effluent discharge monitoring system.
The ORAKEL COD/TOC Sensor provides online continuous organics monitoring utilising a 254nm ultraviolet light source.
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.
