Microprocessor Based Cond-TDS-Salinity-Temp. Meter Microprocessor Based Cond-TDS-Salinity-Temp. Meter is a solid-state instrument designed to provide the precise conductivity/TDS measurements. The instrument uses the latest Microprocessor technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility. The system has user friendly prompts, which guide you through out the measurement process. The system has 6 soft touch membrane type keys for ease of operation. It has the storage facility for 1000 samples, which are retained in the memory even when the system is switched OFF. Provision has also been provided for attachment of Centronics dot matrix printer so that any of the stored results can be printed. The instrument is extremely useful for agricultural and soil analysis laboratories, swimming pools, water quality control in boiler feed water, food processing, pharmaceuticals, water works department, fertilizer plants, petroleum refineries, breweries and beverages, water purification plants etc. Technical Specifications Function Cond. & Temp., TDS & Temp., SAL & Temp.
