Home Our Equipment Water Quality Monitors pH Probe
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.
Our range of ORAKEL pH probe can measure the online pH of any aqueous solution. They are combination glass electrodes with integral reference and automatic temperature compensation which use no reagents, are extremely stable and have reduced maintenance and lower whole-life costs.

pH5 and pH6 are particularly sensitive to difficult applications such as very low ionic strength waters or high temperature applications. The pH1-3 models in the range are less expensive, and have more traditional combination electrodes.
Anywhere you have a requirement to measure pH is a suitable application for the ORAKEL pH probe. One area the sensors excel is in the measurement of pH in very low conductivity or ultra clean water. They are also particularly suited to working in sites where reliability and ease of use are most important.
Typical applications include:
The ORAKEL PH sensors can be installed in a variety of auxiliary flow cells and self-cleaning devices.
The ORAKEL can come equipped to automatically clean itself at user defined intervals with all the benefits of no operator intervention for 6 months. The Autoflush is particularly useful in food preparation, pulp and paper, and many applications where there is likely to be a build up of solids in the sample. Autoflush is available for at line, and in line versions including dip and screw in autoclean pipe version.
Key features and product specification
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 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.
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 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.
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.
