 Introduction
 
 
● design practical, performance excellence, for laboratory and field
● measure mg / l concentration, and air saturation accuracy up to ± 0.03 mg / l or ± 0.3% air saturation
● air saturation mode allows quick and simple calibration procedure becomes, eliminating the measurement probe with the required temperature and atmospheric pressure, so that the oxygen solubility coefficient unknown liquid measurement becomes feasible
● Wide measurement range, 0-20 mg / l or 0-200% air saturation, particularly suitable for the measurement of saturated water samples
● Automatic temperature compensation, excluded due to temperature change caused by the solubility of oxygen permeation coefficient and the effect of
● dial-in salinity inputs, compensation range 0 to 40ppt, including accurate temperature compensation can be directly read dissolved oxygen concentration in the ocean or estuarine
● LCD display with background light function plus, in the dark environment still get a clear reading
● Case waterproof seal, along with record output and Power Interface blocks
● Use the battery or AC operation, battery life is 1,000 hours (carbon-zinc batteries), while the low battery indicator
● can be placed inside the fuselage additional battery packs for field use blender
● with recorder output interface for connection icon recorder or other recording equipment
