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.

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.

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.
