The Pen Type conductivity meter is a specialized, portable instrument designed for assessing the electrical conductivity of aqueous solutions, spanning a wide range from 0 ?S/cm to 2000 mS/cm. Conductivity in such solutions is influenced by the presence of dissolved substances or salts. This device is equipped with an LCD screen, facilitating the monitoring of configured parameters and the display of results for unknown samples or solutions. A key feature is the auto-lock sensor, ensuring stable readings and precise outcomes. Its user-friendly design makes it suitable for use in remote locations where handling complex equipment can be challenging. Additionally, it incorporates automatic temperature compensation for swift and accurate measurements, making it versatile across various temperature environments. This portable pen-type conductivity meter is an invaluable tool for assessing solution conductance in a diverse range of settings.
