STUDY OF PENICILLIN CONCENTRATION MEASURING INSTRUMENT

To detect liquid concentration by a sensor is an advanced measurement method in the range of analysis and measurement. In this paper the study of penicillin concentration measuring instrument whose detector is a biosensor is presented. The principle of signal conversion of the sensor and the principle of signal measurement of the instrument are briefly described, but the emphasis will be placed on the design principle and the structure feature of the measurement unit. The performance parameters of the sensor and the instrument are introduced in detail. The measurement system can show correctly and quickly tile concentration value of penicillin and be operated conveniently too. All tests and applications verify that the results are satisfactory. The sensor measurement method has a wide applicable prospect.
