The CDTX-300 two-wire transmitter is widely used for process control in industry today. This instrument is particularly useful in industrial conditions where electrical interference is an important factor. By galvanically isolating the signals, any interference created is prevented from reaching the transmitter. A loop powered isolator may be required when connecting to data acquisition equipment. The CDTX-300 uses two wires which reduces costs and eliminates the need for expensive coaxial cable. Two-wire transmitters are ideal when used in remote applications that do not have AC power available. The CDTX-300 series conductivity transmitter uses top of-the-line, 4-Ring Potentiometric probes. As opposed to the more widely used 2-Ring Amperometric method, the 4-Ring Potentiometric method provides the highest accuracy and repeatability attainable. When measuring liquids that have a high conductivity, the 2-Ring system is susceptible to polarization. 4-Ring electrodes eliminate the polarization effect by splitting the four rings into 2 current electrodes and 2 voltage electrodes. When placed in a conductive liquid, the 2 current electrodes take the alternating voltage and create a current. This alternating current produces a Buffer Field from which polarization is absent. The voltage is then measured in this field assuring no altered readings.

Provides measurement of electrical conductivity of solvents and paint formulations for electrostatic spray applications.
- Stainless steel probe
- Solvent resistant housing - a must for usage in the paint laboratory
When measuring conductivity, the liquid builds up a specific ohmic resistance to the electric current, depending on the applied voltage. The reciprocal value is the conductivity. The measured resistance depends on the geometric arrangement within the measuring cell. In order to be independent of the measuring cell, the measured resistance has to be divided by the cell constant "C" which yields the so called specific resistance. The specific resistance describes the application and performance properties of electrocoating paints.
The BYK LC 2, BYK-Gardner Conductivity Meter, was developed in cooperation with the VDA (Association of German Automotive Industry) following VDA standards.
Measurement of the resistance of liquid paints is carried out in the annular passage of the dip probe. The measuring cell consists of two separable parts. The electrodes are arranged concentrically (Cat. No. PW-1710) or parallel (Cat. No. PW-1712), thus forming an annular passage. They are insulated from each other.
The electrodes of the measuring cell are made of stainless steel, with the surface polished and therefore easy to clean. Only an absolutely clean measuring cell guarantees that the entire surface of the electrode is available for measurement. The probe is impervious and can be immersed in solvents for a short time.

Honeywell’s complete line of conductivity instrumentation—cells, analyzers/controllers and transmitters—ensures the most reliable conductivity measurements available.
The Model 5000TC inductive magnetic field cell operates on a different principle than the traditional contacting electrode cell. This type of cell is also known as an electrodeless cell or toroidal cell. The instrument sends an alternating current of known value through one of the coils, the primary coil. This current creates a magnetic field and induces a current in the process liquid. This current, in turn, induces a current in the pickup coil. The induced current in the pickup coil is directly proportional to the conductivity of the liquid. No direct contact is necessary between the coils and the solution, thus eliminating potential maintenance problems

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.

HI 8633 and HI 8733 have been designed specifically for use in areas of production and quality control. It is often necessary to test samples with different concentrations ranging from deionized water to brine.
The amperometric system would require constant recalibration and probe changes, thus making the measurement process very time consuming and unreliable. To solve this problem, HANNA instruments has developed the HI 8633, which uses a 4-ring potentiometric probe. The rugged probe is made of PVC - ideal for indoor, as well as outdoor measurements.
By using one point calibration, it is now possible to obtain accurate readings across a very wide range, from 0.1 to 199900 µS/cm.
If temperature of the solution fluctuates, HI 8733, with a built-in temperature sensor and Automatic Temperature Compensation, is the perfect instrument.
As an accessory, HI 721313 is available. The kit includes a rugged carrying case with a beaker, a calibration screwdriver and standardizing solution at 12880 µS/cm.
