Model 1602 Microprocessor Based EC-TDS-Sal Meter – Multi-Parameter Water Quality Analysis System
The Model 1602 Microprocessor Based EC-TDS-Sal Meter is an advanced, solid-state laboratory instrument engineered for the simultaneous, high-precision measurement of Electrical Conductivity (EC), Total Dissolved Solids (TDS), Salinity, and Temperature. By incorporating state-of-the-art microprocessor architecture, this versatile analytical meter minimizes operational variance while ensuring maximum reproducibility and absolute accuracy for critical environmental, industrial, and quality control procedures.
Designed to meet the rigorous demands of modern laboratory workflows, the Model 1602 features an intuitive user interface powered by interactive system prompts. These real-time prompts seamlessly guide operators through step-by-step optimization routines and calibration curves. The instrument displays technical parameters on an integrated 128 x 64 dots Graphical LCD Display, complemented by an ergonomic 8-key soft-touch membrane keypad built for prolonged operational durability.
To eliminate manual range alignment errors, the meter implements a sophisticated Auto Ranging Facility across all chemical concentration bounds. Coupled with an advanced Automatic Temperature Compensation (ATC) system, adjustable cell constants ranging from 0.05 to 10.5, and a programmable temperature coefficient, the Model 1602 guarantees absolute mathematical correction across shifting chemical solutions.
For data management compliance, the platform provides a substantial non-volatile storage matrix capable of holding up to 1000 logged samples. These values remain securely written within internal storage arrays even during total power failures. External logging interfaces are managed via an integrated RS-232 serial printer interface, allowing seamless data transfers to thermal recording systems or standard 80-column Dot Matrix Printers.
