Digital TDS Meter Model RK-98301:
The Model 98301 Digital TDS Meter is a high-accuracy, pen-style instrument engineered for reliable measurement of water quality across various applications. Renowned for its durability and fine finish, this meter provides essential insights into the concentration of Total Dissolved Solids (TDS) in water, making it a valuable tool for professionals and homeowners alike.
Advanced Water Quality Testing:
The 98301 Digital TDS Meter functions by measuring the electrical conductivity of water to determine the amount of Total Dissolved Solids (TDS) present. This concentration, expressed in parts per million (ppm), provides an estimate of the dissolved inorganic salts, minerals, and metals in the water. The device offers a high resolution of 1 ppm across its full measuring range, ensuring precise readings for monitoring water purity.
Essential for Filtration Monitoring:
This digital meter is an indispensable tool for evaluating water treatment systems, such as Reverse Osmosis (RO) or deionization (DI) units. By monitoring TDS levels, users can efficiently track the performance of filtration systems and know precisely when membranes or filters require replacement, ensuring consistent water purification.
Reliable Performance and Design:
The 98301 is manufactured in compliance with prevailing industry standards and is specifically designed for use in several commercial applications. The meter features Automatic Temperature Compensation (ATC) within a range of 0°C to 50°C, which helps ensure accurate readings despite temperature variations in the liquid being tested. Its compact dimensions and lightweight (90g) design make it exceptionally portable for convenient on-site and field testing.
Key Applications:
Due to its accuracy and portability, the 98301 is suitable for a wide array of water monitoring tasks, including:
• Drinking Water Assessment: Quickly checking tap water quality and ensuring safe consumption.
• Aquariums and Hydroponics: Maintaining stable and appropriate mineral levels for aquatic life and plant growth.
• Industrial Use: Monitoring water purity in processes like boiler feed water treatment or general industrial water quality control.
Operation and Care Notes:
To achieve optimal measure accuracy, it is important to gently stir the meter when using it and avoid re-calibrating it unnecessarily. If abnormal phenomena such as high measured deviation or a blinking value occur, the user should immerse the electrode in alcohol for cleaning.
