COND3110 HANDHELD CONDUCTIVITY METERS
Useable anywhere, the WTW Cond 3110 and Cond 3210 handheld conductivity meters are robust, easy to operate and provide assured
accurate readings. From the monitoring of on-line process systems to field studies, WTW's handheld conductivity meters will
meet all your water, wastewater and environmental measurement needs. Both handheld conductivity meters meet IP66/67 standards
– no worrying about using it in the rain and mud, or accidentally dropping it in the water. These handheld conductivity meters
have 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-day demands. With only 6 keys, the Cond 3110 handheld conductivity meter provides easy error-free measurement with temperature measurement, automatic temperature compensation and 4-electrode measuring technology. Typical applications for the Cond 3110 handheld conductivity meter include simple conductivity measurements or use in high schools and universities. Cond 3210 handheld conductivity meter Loaded with additional features, the Cond 3210 handheld conductivity meters include parallel temperature display, integrated datalogger, good laboratory practice (GLP) supporting functions, automatic and manual temperature compensation with linear temperature function and a non-linear function for ultrapure water and natural waters according to EN 27 888. The handheld conductivity meter's temperature compensation can be switched off; either 68 °F or 77 °F (20 °C or 25 °C) can be selected as the reference temperature. The Cond 3210 handheld conductivity meters have a continuous measurement control (CMC) function that alerts you when your meter is reading outside of the calibrated range. The handheld conductivity meter's large memory allows you to manually store 200 datasets. Conductivity is a parameter used to measure the ionic concentration and activity of a solution. The more salt, acid or alkali in a solution, the greater its conductivity. The unit of conductivity is S/m, often also S/cm. The scale for aqueous solutions begins with pure water at a conductivity of 0.05 uS/cm (77 °F /25°C). Naturally occurring waters such as drinking water or surface water have a conductivity in the range 100 – 1000 uS/cm. At the upper end of the chart some acids and alcalines can be found. Conductivity meter measurements are used for applications such as in the production of ultrapure water or determining the salinity of sea water. Conductivity is measured by using a conductivity meter to make a measurement of the electrical resistance. The simplest kind of measuring cell used consists of two similar electrodes. An alternating voltage applied to one of the electrodes causes the ions in the solution to migrate towards the electrodes. The more ions in the solution, the greater the current which flows between the electrodes. The conductivity meter measures the current and uses Ohm's law to calculate first the conductance of the solution and then – by taken the cell data into account – the conductivity. TetraCon® 325 Conductivity Probe The TetraCon® 4-electrode system sets a new standard for professional conductivity measurements. In comparison with conventional measuring cells with 2 electrodes, the TetraCon® 325 conductivity cell offers numerous technical advantages:
We offer both of these great handheld conductivity meters with a conductivity probe in two convenient kits to make your life easier. Sets include: A Cond 3110 or 3210 handheld conductivity meter, TetraCon® 325-3 probe with 9.8 ft cable, heavy duty fitted case, cal solution, beaker and even a handy probe holding arm. You will have everything you need for field or plant conductivity measurements in one case. |
