Overview
The American Visay/YSI laboratory dissolved oxygen measuring instrument is suitable for laboratory and field use, with a wide measurement range and automatic temperature compensation. Clear display of readings. Design practical, expressive, and suitable for laboratory and field use. It can measure concentration in milligrams per liter and air saturation with an accuracy of up to 0.03 milligrams per liter or 0.3% air saturation. The air saturation mode makes the calibration process fast and simple, eliminating the need to measure probe temperature and atmospheric pressure, making it feasible to measure liquids with unknown oxygen solubility coefficients.

Main features of the product:
Design practical, expressive, suitable for laboratory and field use
Measurable milligrams/Enhance concentration and air saturation with high accuracy±0.03mg/Rising or±0.3%air saturation
The air saturation mode makes the calibration process fast and simple, eliminating the need to measure probe temperature and atmospheric pressure, making it feasible to measure liquids with unknown oxygen solubility coefficients
Wide measurement range,0to20mg/Rising or0to200%Air saturation, particularly suitable for measuring supersaturated water samples
Automatic temperature compensation eliminates the effects of membrane permeability coefficient and oxygen solubility caused by changes in water temperature
Direct dial salinity input, compensation range0to40ppt, including accurate temperature compensation, can directly read the dissolved oxygen concentration in the ocean or estuary
LCD screen with background lighting function, can still read clearly in dim environments
The body shell is sealed and waterproof, and comes with a cover for recording output and power interface
Operated using batteries or AC power, with a battery life of1,000Hour (carbon zinc battery), with low battery display
Additional battery packs can be placed inside the body for use with outdoor mixers
Equipped with a recorder output interface, used to connect icon recorders or other recording equipment
