อุปกรณ์วัด ออกซิเจนละลาย (Benchtop Oximeter with color display)

HI 4421-02 


Benchtop Oximeter with color display

HANNA presents a new family of benchtop instruments which, thanks to its many functions and advanced features are able to meet all the needs of laboratories and research departments. Among the main features include the large color graphic display (240 x 320 pixels) with on-screen help, simultaneous graphing, language selection and configuration customization.
Oximeter HI 4421, through the development data, is able to provide measures (compensated both in temperature and in salinity) expressed in% over that of saturation in ppm and even as BOD (Biochemical Oxygen Demand), OUR (Oxygen Uptake Rate) and SOUR (Specific Oxygen Uptake Rate ). This tool includes a barometric pressure gauge and the possibility of calibration with user selectable units (mmHg, mbar).
HI 4421 is equipped with the manual or automatic recording of data (100 lots to 10,000 measurements) as well as the information regarding the BOD, OUR and SOUR. This data can then be transferred to a PC through the USB or RS232 ports and HI 92000 software (optional).
