EI-DVI Digital TDS Meter Model 652 (Deluxe Series):
Product Overview:
The EI-DVI Model 652 Digital TDS Meter (Deluxe Series) is a highly accurate and reliable test instrument designed for the precise measurement of Total Dissolved Solids (TDS) in aqueous solutions. Engineered with the latest microcontroller technology, this meter offers exceptional versatility by accurately measuring both TDS concentration and temperature simultaneously.
Featuring an Auto Ranging facility and Automatic Temperature Compensation (ATC), the Model 652 simplifies complex water quality monitoring across multiple environments, ensuring measurements are consistently accurate and easy to obtain.
Key Features and Advantages:
Advanced Microcontroller Technology:
The core functionality is driven by advanced microcontroller technology, providing precise and stable readings essential for professional laboratory and industrial applications.
Dual Measurement Capability:
Unlike standard meters, the Model 652 measures both the TDS concentration (in ppm/ppt) and the temperature (°C), offering a comprehensive view of water quality.
Automatic Temperature Compensation (ATC):
The instrument features Automatic Temperature Compensation (ATC) through an included temperature probe, adjusting readings to compensate for temperature fluctuations across a wide range (0 to 50°C). This ensures highly accurate TDS results regardless of the sample temperature.
Auto Ranging for Precision:
The device automatically selects the most appropriate measurement range from five available options, ensuring optimal precision and a high resolution of 0.1 ppm in the lowest range.
Convenient Cell Constant Management:
The cell constant is adjustable and displayed digitally on the front panel. It also provides a facility for automatic measurement of the cell constant using a known standard solution.
Ideal Applications:
The Model 652 Deluxe TDS Meter is an extremely useful instrument for monitoring water purity and dissolved salts. It is ideally suited for:
• Agriculture and Soil Analysis Laboratories
• Swimming Pools and Aquariums
• Fertilizer Plants and Chemical Processing
• Mineral Water and Packaged Drinking Water Plants
• Petroleum Refineries and Textile Plants
