Essential Solutions to Keep Your Conductivity Meter Accurate and Reliable

About Conductivity

Conductivity or electrical conductivity (EC) is the measure of the concentration of ions present within a sample. Electrical Conductivity is the ability of the substance to transmit an electrical current over a defined area. The measurement unit for electrical conductivity is called Siemens(S), and scientific instruments typically display measured units as MilliSiemens per centimetre mS/cm or Micro Siemens per cm μS/cm.

Why Calibrate Conductivity

Maintaining the regular calibration of your conductivity meter will guarantee precise and dependable readings. The frequency of calibration required will depend on how often you operate your device as well as the required accuracy of the device. For example, if you use your meter every day (say, in a professional setting), you should calibrate it daily. If you only use your meter a few times a week or for spot tests around the home, weekly calibration is adequate. The calibration of most conductivity meters is straightforward and performed in a matter of minutes.

Conductivity Solutions

The best way to ensure accurate calibration of conductivity on your meter is to use a commercially produced standard solution. For conductivity, the most common conductivity calibration standard solution is 1413µS/cm. However, check your manual as some meters will only calibrate to specific points, or perhaps multiple points, especially when testing various ranges of conductivity.

All conductivity calibration standard solutions come pre-prepared and ready to be dispensed into clean containers for calibration. Instrument Choice has several solutions of varying concentrations available. The two most popular calibration solutions are;


1. Conductivity Calibration Solution (1413uS-cm) 500 mlConductivity%20Calibration%20Solution%20(1413uS-cm)%20500%20ml.jpg

Ensure Your Data Loggers Are In-Check With Our Instrument Calibration Services

Calibration is critical wherever measurements need to be relied on when you make decisions that can have significant legal, educational, financial, social or health and safety outcomes. In such situations, managers and operators need confidence in the results that they monitor, record and ultimately control.

As data loggers work in systems to record data that has been captured by sensors, the accuracy and precision of any system that uses a data logger will be affected by all devices operating in that system. 

This article outlines how Instrument Choice instrument calibration services play a major role in helping educational institutions, governments, businesses and professionals ensure the accuracy of any measuring system that uses a datalogger.
