Objective

Microprocessor Based Dissolved Oxygen Meter is a solid state instrument designed to provide the precise DO and Temperature measurements. The instruments 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 throughout measurements process.

The system has 8 soft touch membrane 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 made for attachment of dot-matrix/thermal printer with RS232 serial interface so that any of the stored results can be printed.
