Instrument characteristics
TECHNICAL INDEX
Instrument features:
Dissolved oxygen units can be selected in mg/L, ppm,% saturation, with an accuracy of up to ± 0.5% of full range
100% saturation automatic calibration, can also perform 0% saturation automatic calibration simultaneously during low concentration measurement, with higher accuracy
Under different conditions, temperature, salinity, and atmospheric pressure compensation make the measurement results more accurate
• Can store 500 records with date and time, compliant with GLP standards
Bidirectional RS232 facilitates data transmission
Calibration expiration reminder function
The automatic storage function facilitates continuous measurement
• Over range alarm function can be set
Menu and calibration can be password protected
