SCHOTT Instruments IoLine – pH electrodes for the most demanding measuring tasks
The new IoLine electrode family with iodine/iodide reference system from SCHOTT Instruments has been developed to meet the most demanding laboratory measurement tasks. These electrodes are 100% metal ion free and hence ideally suited for measurements that are critical towards sample contamination by such ions (e.g. silver ions) and for pH measurements in Tris buffers too.
Advantages of IoLine Electrodes over classical Ag/AgCl reference systems are notably by:
• A longer service life thanks to a patented three-chambers Iod reservoir in the reference electrode.
• Fast reaction, precise measurement and clearly improved stability of measurement values, especially with changing temperatures or at temperatures other than the calibration temperature. This is due to the lower temperature sensitivity of the iodine/iodide reference potential.
• Free choice of the bridge electrolyte, hence optimum adaptation to the sample by double electrolyte system.
The electrodes are available in different membrane glass shapes and types and with different plugs to ensure that the user gets the instrument best suited to his needs. ID versions are available for use with SCHOTT Instruments’ ProLab line of high-end laboratory meters.
IoLine electrodes are the right choice for the most critical pH measurements in research and quality control in pharmacy, biotechnology or food industry. |

This economically designed meter is ideal for use in process control monitoring or anywhere a small, accurate meter is needed. The VARIO is small, light, handy, waterproof and has a robust firmgrip rubber armoring.
Miniature precision, the VARIO Cond Sets:
• The VARIO Cond KIT with 4 electrodes conductivity cell: The globally renown measuring cell TetraCon® 325 was specially shortened and modified for the VARIO Cond. Therefore very precise measurement in the range from 10 µS to 200 mS can be done.
• The VARIO Cond KIT with ultrapure water cell and flow-through vessel: A 2 electrodes stainless steel cell for ultrapure water with plug head and flow-through vessel and a cell constant of 0.1 enables measurements down to 0.1 µS.
Increased precision through the omission of cable connectors – the VARIO Cond is suitable for all measuring tasks for drinking water, process technology, semiconductor technology or pharmaceutical industry.

electrical current. As the ranges in aqueous solutions are usually small, the basic units of measurements are milliSiemens/cm (mS/cm) and microSiemens/cm (µS/cm).
Conductivity is used widely to determine the level of impurities in water supplies for domestic consumption as well as industrial use. Industries that employ this method include the chemical, semi-conductor, power generation, hospitals, textile, iron and steel, food and beverage, mining,
electroplating, pulp and paper, petroleum and marine industries.
Specific applications include chemical streams, demineraliser output, reverse osmosis, stream boilers, condensate return, waste streams, boiler blowdown, cooling towers, desalinisation, laboratory analysis, fruit peeling and salinity level detection in oceanography.
Some applications require the measurement of Total Dissolved Solids (TDS) in mg/L, parts per million (ppm) or parts per thousand (ppt). The TDS concentration can be obtained by multiplying the conductivity value with a factor which is empirically determined. The total TDS is a mass estimate and is dependent on the mix of chemical species as well as the concentration while Conductivity is only dependent on the concentration of chemical species.
Eutech offers a wide range of conductivity meters for these various applications. |

ELECTRODE-HOLDERS
The sensors for pH, Redox and Conductivity have to be installed on the system using proper electrode holder that guarantee the correct mechanical protection and the water proof degree.
The electrodes of pH and Redox can be immersed in tanks, inserted in pipes or put in proper containers for the passage of sample liquid drawn from the system.
It is very important to lay stress on the immersion models with adjustable flange that has to be linked together with the counter flange that allows their fast extraction. The version with floating platform suits to follow the free water surface in deep tanks.
The versions for two electrodes in polypropylene allow to put in the same armature two sensors example pH and Redox).
