HandheldConductivity Meters Product Description

Useable anywhere, the WTW Cond 3110 and Cond 3210handheld conductivity meters are robust, easy to operate and provide assuredaccurate readings.ÿ From the monitoring of on-line process systems to fieldstudies, WTW’s handheld conductivity meters will meet all your water, wastewaterand environmental measurement needs.ÿ Both handheld conductivity metersmeet IP66/67 standards ? no worrying about using it in the rain and mud, oraccidentally dropping it in the water.ÿ These handheld conductivity metershave incorporated a sealed silicone keypad which offers real button response,yet allows for easy cleaning.

Cond 3110 handheld conductivity meter
This easy to use handheld conductivity meter will meet all your day-to-daydemands.ÿ With only 6 keys, the Cond 3110 handheld conductivity meterprovides easy error-free measurement with temperature measurement, automatictemperature compensation and 4-electrode measuring technology.ÿ Typicalapplications for the Cond 3110 handheld conductivity meter include simpleconductivity measurements or use in high schools and universities.

Cond 3210 handheld conductivity meter
Loaded with additional features, the Cond 3210 handheld conductivity metersinclude parallel temperature display, integrated datalogger, good laboratorypractice (GLP) supporting functions, automatic and manual temperaturecompensation with linear temperature function and a non-linear function forultrapure water and natural waters according to EN 27 888.ÿ The handheldconductivity meter’s temperature compensation can be switched off; either 68 øFor 77 øF (20 øC or 25 øC) can be selected as the reference temperature.ÿThe Cond 3210 handheld conductivity meters have a continuous measurement control(CMC) function that alerts you when your meter is reading outside of thecalibrated range.ÿ The handheld conductivity meter’s large memory allowsyou to manually store 200 datasets.

Conductivity meter measurements
Conductivity is a parameter used to measure the ionic concentration and activityof a solution.ÿ The more salt, acid or alkali in a solution, the greaterits conductivity.ÿ The unit of conductivity is S/m, often also S/cm.ÿThe scale for aqueous solutions begins with pure water at a conductivity of 0.05uS/cm (77 øF /25øC).ÿ Naturally occurring waters such as drinking wateror surface water have a conductivity in the range 100 ? 1000 uS/cm.ÿ Atthe upper end of the chart some acids and alcalines can be found.

Conductivity meter measurements are used forapplications such as in the production of ultrapure water or determining thesalinity of sea water.

Conductivity is measured by using aconductivity meter to make a measurement of the electrical resistance.ÿ Thesimplest kind of measuring cell used consists of two similar electrodes.ÿAn alternating voltage applied to one of the electrodes causes the ions in thesolution to migrate towards the electrodes.ÿ The more ions in the solution,the greater the current which flows between the electrodes.ÿ Theconductivity meter measures the current and uses Ohm’s law to calculate firstthe conductance of the solution and then ? by taken the cell data into account? the conductivity.

Handheld conductivity meterapplications
Using the TetraCon? 325 electrode the Cond 3110 and 3210 handheld conductivitymeters will work well in ground water, surface water, laboratory, food industry(juice), swimming pools, pharmaceutics, paint/varnish (soluble), orelectorplating measurement applications.

TetraCon? 325 Conductivity Probe
The TetraCon? 4-electrode system sets a new standard for professionalconductivity measurements.ÿ In comparison with conventional measuring cellswith 2 electrodes, the TetraCon? 325 conductivity cell offers numeroustechnical advantages:

• Highly accurate and linear because of optimized cell geometry
• Extremely large measuring range with just one cell
• Long-term cell constant stability with high-quality abrasion-resistant graphite electrodes
• Built-in temperature sensor as standard
• Smallest immersion depth possible
• Automatic resistance compensation provides accurate measurements even with a dirty electrode
• Measurement not affected by cable influences, polarization effects or contact with side walls
• Robust, unbreakable epoxy body

Handheld Conductivity Meter Sets
We offer both of these great handheld conductivity meters with a conductivityprobe in two convenient kits to make your life easier.ÿ Sets include: ACond 3110 or 3210 handheld conductivity meter, TetraCon? 325-3 probe with 9.8ft cable, heavy duty fitted case, cal solution, beaker and even a handy probeholding arm.ÿ You will have everything you need for field or plantconductivity measurements in one case.
