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
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 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 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.
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 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 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.
