LDR-8 series dissolved oxygen meter are used to measure amount of gaseous oxygen dissolved in a liquids.
Automatic Calibration:
LDR-8 series with two points calibration function (Zero and 100%), it can recognizing calibration solution. If you use calibration solution by mistake, the meter will display ERROR.
Automatic Temperature Compensation:
Automatic temperature compensation guarantees the highest accuracy under varying temperature condition.
Salinity and Barometric Pressure Compensation:
The salt dissolved in solution will limit oxygen content. LDR-8 series can compensates salinity and barometric pressure after manual input coefficients.
Multi-Measurement Units:
LDR-8 series can set parameter units accord with your country. E.g, Dissolved oxygen units: mg/L and ppm; Barometric pressure units: kPa and mmHg; Temperature units: oC and oF.
Hold Function:
The meter with hold function, press [ MEAS/HOLD ] key, the meter momentarily freezes reading for easy viewing.
Save & Output Data:
The meter can save 48 data sets, press [ SAVE ] key, the meter will store current measured value, serial number, date, time and other information. The data can be sent to computer through USB link, you can print out test report via software.
