PH METER
MAKE DINESH SCIENTIFIC MODEL DS-PHM-202
DESCRIPTION
PH METER is a solid state instrument designed to provide the precise Ph and mV 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 8 soft touch membrane type keys for ease of operation. It has facility for doing up to 5 point calibration. It has the storage facility for 1000 samples, which are retained in the memory even when the system is switched OFF. Provision has been provided for attachment of dot matrix/thermal printer through serial Rs232 so thatany of the stored result can be printed. The instrument is extremely useful for agriculture and soil analysis laboratories, swimming pools, water quality control in boiler feed water, water works department, fertilizer plants, petroleum refineries, breweries, water purification plants etc.
