Home Our Equipment Water Quality Monitors ORAKEL
The ORAKEL System is a powerful, modular water quality monitoring solution designed to meet UK and international environmental standards. Equipped to measure key parameters like dissolved oxygen, temperature, pH, and turbidity, it offers real-time insights and compliance support for ecosystems and water bodies. Mains-powered with remote data communication options, the ORAKEL System is ideal for environmental monitoring in rivers, lakes, stormwater systems, and more.
The ORAKEL System is the perfect choice for comprehensive environmental water monitoring, offering accurate, simultaneous measurement of water flow and quality. Designed as a flexible, modular solution, it supports a diverse range of water quality sensors to monitor critical environmental parameters—including pH, COD, and turbidity—enabling tailored, cost-effective solutions that align with the needs of today’s regulatory landscape.
Environmental monitoring requirements have never been more stringent. ORAKEL’s robust system is designed to meet both UK and international legislative standards, including the Environment Act’s Section 82, which mandates proactive water quality monitoring and reporting. This system aligns with global standards for environmental data collection, supporting initiatives that target pollutant control, river health, and habitat protection. By seamlessly integrating flow and water quality measurement in one system, ORAKEL
The ORAKEL System is purpose-built to monitor critical water quality parameters—dissolved oxygen (DO), temperature, pH, and turbidity—ensuring comprehensive environmental monitoring and compliance with both UK and international water quality standards. Its modular, mains-powered design allows for simultaneous tracking of these key parameters, aiding in the protection of water ecosystems while fulfilling stringent global regulatory requirements.
Designed to meet both UK standards under Section 82 of the Environment Act and global requirements, the ORAKEL System is an ideal choice for organisations needing reliable, compliant water monitoring solutions. International regulations include:
The ORAKEL System includes communication options such as Profibus, Modbus TCP, and optional GSM data logging, enabling remote data access and compliance reporting. This feature provides environmental professionals with up-to-the-minute information for detailed analysis and timely response.

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 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.
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 Oxygen applications.
