HI 2300 performs EC, TDS (Total Dissolved Solids), percentage of NaCl and temperature measurements. The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample.
All measurements can be temperature compensated at 20 or 25°C and the compensation coefficient is selectable by the user. The automatic temperature compensation can also be disabled for measuring the actual conductivity value. The stability indicator on the LCD ensures accuracy.
Conductivity readings are performed by applying an alternate current to the 4-ring probe which creates a variable voltage directy proportional to conductivity.
The GLP feature allows users to store and recall data about system status.

A pH electrode that is properly manufactured and kept clean will retain its measuring integrity for quite a long time.
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note because, during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration.
pH meters on the market today will allow an offset of approximately ±60 mV. The deviation from 0 mV is not unusual, in fact it represents the true characteristics of the pH electrode. The deviation from 0 mV becomes a problem if it is the result of calibrating a dirty electrode.
HANNA instruments' HI 221 & HI 223 compare the characteristics of the pH electrode from one calibration to the next. In case of large variances in the electrode condition that can only be the result of a soiled sensor, these meters alert the user that the electrode needs to be properly cleaned prior to calibration and measuring.

ATI Models Q45H62 and Q45H63 are reagentless and designed for on-line monitoring and control of chlorination systems. It is available in two versions: a free chlorine monitor for drinking water and cooling water, and a combined chlorine monitor ideally suited for “chloraminated” drinking water. The combined chlorine system can also be used in wastewater effluents where sufficient ammonia is present prior to chlorination to result in a predominantly monochloramine residual. Unlike on-line colorimetric and most amperometric monitors, Q45H systems utilize a membrane-covered polarographic sensor that does not require the addition of chemical reagents. The Q45H system has no moving parts, so there are no pumps or motors that burn out or tubing breaks that create maintenance nightmares. All normal maintenance items are included with each system.

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 offers a wide variety of conductivity cells to satisfy your process needs, from sensitive ultra-pure water applications to highly conductive industrial processes. Our cells are constructed of rugged materials, guaranteeing longer cell life. Honeywell offers both contacting and toroidal cell designs allowing you to select the conductivity cell best suited for your application, providing a wide range of capabilities and ensuring accurate conductivity measurements. All conductivity cells have integral temperature compensators that are compatible with Honeywell instrumentation. An assortment of mounting options—in-line, immersion or insertion/removal—reduces your installation costs. 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

No water supply is completely pure. Every industrial, commercial, or natural source contains dissolved solids or salts. These impurities contribute to scale, corrosion, poor taste, and environmental pollution that endanger animal and plant life.
Myron L Company has two proven ways to measure such impurities. Our DS Meters™ provide fast, accurate, on-the-spot measurements of total dissolved solids (TDS) or conductivity. pDS Meters™ test conductivity or TDS, plus pH. Readings from their highly stable circuitry help assure product quality, prevent equipment damage and verify in-line instrumentation in a wide range of applications, some of which are listed above.

The CF60 conductivity sensor features a superior six-electrode, four-pole design. The patented arrangement of the four current electrodes around the two potential electrodes results in a reliable and precise measurement of a broad conductivity range from 1 µS/cm up to 850 mS/cm. This unique design also provides greatly reduced sensitivity to sensor fouling and polarization. Designed for ultra-sterility, the six electrodes are sealed in the FDA-compliant PEEK sensor tip without the use of o-rings or epoxies.
A Pt1000 platinum RTD is integrated in the tip of the CF60 sensor providing fast-response temperature compensation. The optek inline sensor body ensures smooth and unrestricted flow of all process fluids with minimized hold-up and hydrostatic shear. This unique design results in rapid sensor response, precise measurements and maximized product recovery and quality.
Manufactured using only certified and traceable materials of the highest quality, the CF60 can be provided with special wetted parts for superior resistance to the acids, bases as well as organic and inorganic solvents. The CF60 sensor is suitable for CIP/SIP applications.

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. 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. Eutech offers meters that allow the direct reading
of TDS values. These include the TDSTestr™ series, EcoScan TDS 6, CyberScan Standard Portables CON 11, CON 110 and Waterproof Portable CON 410. Bench meters for advanced level laboratory research are the CyberScan CON 510, CON 1500 and colour touchscreen research-grade CON 6000.
