YSI52 laboratory dissolved oxygen meter YSI DO

YSI52 laboratory dissolved oxygen meter? Climax dissolved oxygen meter YSI has full functionality, and to middle and low price position of universal models can be used for laboratory and field testing. ? High Accuracy: microprocessor control and accuracy on the market far more than other general models * Large LCD display: simultaneous display of air saturation, mg / l dissolved oxygen, temperature and time; parameters without transcoding?? file read, quick time · RS232 interfaces:? All instrument functions can be written by the user software to directly control Non-volatile flash memory loss:? store 70 groups of dissolved oxygen and temperature data, each reading are accompanied by Date , time and test or test number label; the stored data can be recalled on the display * uploaded to a computer or serial printer; stored data is not lost due to power Automatic stabilization enroll? Function: When the test readings reach? When stable condition set by the user, the instrument will automatically make the instructions to ensure maximum stability · readings and YSI 5905 probe, YSI 5120 BOD type analysis software is compatible with the technical parameters:????? dissolved oxygen (% air saturation °) Measurement range Resolution Accuracy 0.0 to 199.9% air saturation 0.1% ± 0.1% air saturation of air saturation +1 lsd (least significant bits) Dissolved oxygen (mg / l) Measurement Range Resolution Accuracy 0.0 to 19.99 mg / L 0.01 mg / L ± 0.03 mg / l Temperature test and measurement range Resolution Accuracy temperature of -5 to + 45 ℃ ± 0.1 ℃ ± 0.1 ℃ Accuracy Compensation Measurement range 0 to + 45 ℃ 5 to + 45 ℃: ± 0.6% mg / L reading; ± 0.3% air saturation calibration value; 0 to + 5 ℃: ± 1% mg / L reading; ± 0.5% air saturation calibration salinity compensation Measuring range Resolution Accuracy 0 40ppt0.01ppt of ± 1.0% of reading or 0.1ppt, whichever type of data storage capacity of the non-volatile memory loss 70 sets of readings (dissolved oxygen, temperature, date and time) Operating ambient temperature and humidity waterproof -5 to +45 ℃ 10 至 90% (non-coagulation) beyond the IP65 standard power 6 1 battery Typical battery life: 100 hours (alkaline batteries) Low battery indicator AC adapter (230 V AC) Dimensions 21.6 cm (length) × 28.0 厘米(width) × 9.5 cm (thickness)?
