PH meter is an electronic device that accurately determines the acidity, alkalinity, or neutrality of liquids by examining and measuring the activity of hydrogen ions in solutions. This device is widely used in various industries such as food and beverage, agriculture, pharmaceuticals, oil and gas, water treatment plants, and more, making it a practical and important tool for industrial applications.
pH (potential of Hydrogen) is a scale used to determine the acidity or alkalinity of a solution. pH meters typically display the pH value between 0 and 14. The lower the pH value, the more acidic the solution, and the higher the pH value, the more alkaline it is. When evaluating a solution at room temperature (25 degrees Celsius), if the pH value is above 7, the solution is basic; if it is below 7, it is acidic, and if the device displays a pH value of 7, the solution is neutral.
The accuracy of a pH meter in measuring the pH of solutions can be crucial in many industries. Nowadays, choosing a pH meter with high accuracy and reasonable price is a concern for laboratory professionals. Kaspin Jam Azma Company, as one of the reputable importers of laboratory equipment, has imported high-quality and highly accurate pH meters from METTLER TOLEDO after examining various brands available worldwide.
This article aims to review and compare the pH meter manufactured by the reputable company METTLER, so that laboratories and professionals in this field can make better choices according to their needs
Series SEVEN COMPACT :
It can be said that this series of METTLER’s pH meters is a revolution in the pH meter manufacturing industry. Flexibility, innovative design, and ease of use have made the Seven Compact series an ideal choice in this field. While these devices encompass a wide range of measurement parameters and offer numerous options for data input and storage, their calibration and measurement are as easy as pressing a button.
This device complies with the GLP (Good Laboratory Practice) standard in the pharmaceutical industry and testing laboratories.
Design and User Interface of the Device:
Working with this device is so easy that you can start your work by simply pressing a button. The 4.3-inch colorful display has made working with this device highly enjoyable. The high image clarity with large numbers and beautiful iconography is another characteristic of this display. The color and contrast of the screen are adjustable, allowing you to make changes according to your lighting conditions.
Measurement modes and calibration are easily visible and adjustable. In the device menu, you can set an audio signal as an alert to notify you of pressures or endpoint stability. The electrode arm of this device is designed in a way that allows you to easily raise and lower it and move it in various directions with one hand, reducing the risk of spilling substances.
GLP-related security package:
The Seven Compact has stringent security functions to support your data. These functions are defined based on GLP standards and help you protect your information. Access is defined based on the user’s needs for the device in all calibration, measurement, data collection, and data archiving stages. The device’s adaptability is also reflected in its security package. The level of user access, whether it requires predefined settings or full access to all settings, can be defined on the device. In routine mode, data deletion or modification is blocked, but an authorized user can adjust all the information according to the desired settings.
