 Instrument Description: 
 Generation YSI ROX optical dissolved oxygen sensor using fluorescence lifetime detection technology, for users in serious pollution and low oxygen waters of long-term monitoring of dissolved oxygen conditions provides the most powerful tool. Rugged design and wide measurement range makes random water quality testing, groundwater monitoring flow chamber measurements and the ideal choice. 

 YSI companies have found that scientists and technicians who currently work in the field in the challenge. Our technical staff regularly with our users in the wild, fighting side by side, access to a number of first-hand information. The lessons learned in practice, ROX optical dissolved oxygen sensor has been used in the design. 

 Quality control and quality assurance ROX 
 As relevant to users and improve the calibration and quality assurance / quality control data commitment, each ROX sensor package of factory calibration coefficients are preloaded to ensure the accuracy of the sensor. 


 Technical parameters: 
 Optical Dissolved Oxygen (% air saturation): measuring range 0-500%; Resolution 0.1%; 0-200% Accuracy: ± 1% of reading or 1% air saturation, whichever is greater; 200 - 500%: ± 15% of reading 

 Optical Dissolved Oxygen (mg / l): measuring range 0-50 mg / l; resolution of 0.01 mg / l; accuracy of 0-20 mg / L: ± 1% of reading or 0.1 mg / L, the greater the standards; 20-50 mg / L: ± 15% of reading 

 Methods of work 
 ROX sensor system using fluorescence lifetime techniques, this method can provide the most stable, most repeatable and most sensitive test data of dissolved oxygen, which can effectively reduce the drift of the sensor to extend the running time. 

 ROX electrochemical dissolved oxygen sensor membrane is different from traditional film, installation is simple, maintenance-free service life up to one year. In addition, the use of durable material, is almost impossible to use in the field damage. ROX sensor is not velocity dependent, can be used in low flow or no flow in the environment. 

 Dissolved oxygen sensor with fast pulse compared, ROX sensor has the following advantages: 
 * No flow dependence 
 * Maintenance-free, anti-stab film 
 ? No electrolyte 
 * Self-cleaning function, put on a longer 
 * Impact of hydrogen sulfide from 
 * Optional zero calibration 


 Main features: 
 * Oxygen detection using fluorescence lifetime, provide the most stable measurements 
 * Microprocessor control measurement system, effectively reduce the drift data to improve accuracy 
 * Easy to install, replace the membrane, the service life up to one year 
 * Optical ports with multi-parameter YSI 6 series is fully compatible monitor water quality, upgrade the software from YSI website (www.ysi.com) free download 
 * Not subject to flow restrictions, without stirring 
 * Simple point or two-point calibration 
 △-point calibration: air saturation point 
 △ two-point calibration: zero and the air saturation point 
 ? The poor working environment, self-cleaning ability to play a super clean sweep system integration, the following features: 
 △ innovative clean sweep switch controlled positioning system to ensure accurate and clean sweep of the dock location 
 △ corrosion resistance of titanium metal brush shaft at high hydrogen sulfide (H2S) to work long hours with low oxygen environment 
 * Measuring range than any other optical dissolved oxygen sensor is more broad; measurements of dissolved oxygen sensor data and rapid pulse entirely relevant
