What is a conductivity meter used for?
Conductivity meter allows us to measure the level of conductivity in solutions. Conductivity is an ability of materials (solutions, metals or gases) to pass an electric current.
Do conductivity meters need to be calibrated?
Electrical conductivity (EC) is the measure of the concentration of ions present within a sample. Conductivity is the ability of the substance to transmit an electrical current over a defined area. A conductivity meter measures the level of conductivity within an aqueous solution using either two or four probes.
How can you test the accuracy of an instrument such as a conductivity meter?
To ensure an accurate result, the instrument is usually calibrated with one of more standards prior to the measurement. To make accurate measurements, a conductivity instrument is usually calibrated using potassium chloride (KCl) solutions of known concentration.
How do you use a conductivity tester?
Test if a solution conducts electrical currents: Fill a cup with salty water or other ionic solution, and then rest the device on the rim of the cup (make sure the aluminum leads are immersed in the solution). If the light bulb glows brightly, then the solution is very conductive.
How does a conductivity tester work?
Electrical conductivity is measured by conductance between two or four electrodes using amperometric or potentiometric methods. When submerged in a sample the electrodes pass a current through the sample solution.
How much does a Hanna Meter Meter cost?
The meter was also very affordable at a price point less than $50.00. Since the introduction of the pHep, Hanna Instruments has been at the forefront of innovating tester technology.
What kind of tester does Hanna Instruments use?
Hanna Instruments offers a wide selection of pH and ORP testers. Choose from the latest pHep to the iconic Checker ® that has been used in schools all over the world. Available options include testers with replaceable electrodes, multi-level LCD, or the Piccolo ® that has an amplified probe, making it immune to electrical noise interference.
How did Hanna Instruments change the way pH is measured?
In 1986, Hanna Instruments revolutionized the way pH is measured with the introduction of the pHep ® (pH electronic paper). This tester brought electronic pH measurement out of the lab, giving the general public, farmers, students, and many other users access to a pH meter that was highly accurate and simple to use.
What can I do with a 99 series conductivity meter?
These 99 Series Conductivity/TDS Meters make precision measurements simple. An IP67 body and two-button design make these handheld meters ideal for water quality testing in the manufacturing and environmental industries.
