With a detection range of 0-100%, ±0.15% precision at low oxygen levels, and a rapid 10-second response time, it ensures safety and efficiency. Its compact size and 500-hour battery life make it an indispensable tool for professionals demanding reliable oxygen analysis on the go. ## Description The instrument's sensor adopts advanced oxygen electrode manufacturing process technology, which achieves long life, high stability, high precision, fast response time, and can resist the interference of various harmful gases (especially the interference of hydrogen). The oxygen electrode produced by our factory has also obtained Chinese patents. The instrument host is assembled by an imported A/D conversion circuit and digital display, which has the characteristics of easy operation and wide range of 0.00%-100%, particularly suitable for the following occasions. The sensor of the instrument is an electrochemical polarographic diaphragm oxygen electrode. It uses a platinum cathode and a silver-silver chloride anode. Potassium chloride is used as an electrolyte, and the diaphragm material is a polyperfluoroethylene propylene film selected to transmit oxygen. The electrode reaction is as follows Cathode: O ₂ + 2H ₂ O + 4e → 4OH⁻ Ag + Cl⁻ → AgCl The electrode current is proportional to the oxygen content in the gas, driven by analog conversion and decoding, and displays the percentage of oxygen through a digital screen. Technical performance 1. Range Accuracy 0-100% Minimum resolution is 1% ±3%. 0-50.0% The minimum resolution is 0.1% ±1%. 0-5.00% Minimum resolution is 0.01% ±0.5%. 2. Ambient temperature: 0-40°C, humidity <90% 3. Response time: 5 seconds to indicate 90% of the oxygen concentration (20°C) 4. Sampling method: hand pinch suction type 5. Power supply: 9V lithium battery, can work continuously for 200 hours 6. Dimensions: 125×70×25 mm 7. Weight: 200g 8. Stability: 8 hours ±1%.How to use Rotate the switch to 50 gear and stabilize for about 3 minutes (the number of just started up drops from large to small, and the descent is the balancing process of the electrode, which is a normal phenomenon). Pinch the suction balloon 2-3 times, inhale the fresh air, and adjust the 21% twist so that the LCD screen displays 21.0 After the above work is completed, the instrument can be on-site detection, the sampling device is connected to the gas outlet to be measured, the other end is connected to the suction balloon, and the suction balloon is pinched 3-4 times. The oxygen content in the measured gas can be obtained after the reading is stable. If the measured value is higher than 50%, the switch is rotated to 100%, and when it is lower than 5%, the button is turned to 5% to improve data accuracy. After the inspection is complete, rotate the switch to the OFF position. The maintenance of the instrument This instrument uses a diaphragm oxygen electrode in a clean gas and relative humidity of about 85 environments, generally can be used for two years left and right, such as electrode aging can not be used, immediately send the instrument back to the factory for repair, maintenance costs are calculated separately. During use, the instrument's sensitivity decreases significantly as the use time is extended, caused by organic matter and dust contamination in the gas to be measured. This can be solved by treating the gas cleanly during sampling, which is the key to extending the life of the electrode. Fault: ① If the instrument's response is slow during the test and there is a significant drift after calibration, the principle is that there is water vapor or water vapor on the electrode head. Dust, please gently dab the water ball and dust with cotton wool to remove. ② If the calibration cannot be performed: 1. The air permeability is decreased due to the contamination of the diaphragm. 2. There are sharp objects to scratch the diaphragm, and the electrodes are aging. ③ If the LOBAT indicator in the upper right corner is on, the battery voltage is insufficient, and the back cover should be opened to replace the new battery. Note: If the instrument is not used for a long time, please remove the battery. ## Features - 1. Determining oxygen content in the environment of industrial and mining enterprises, cabins, tunnels, variable pressure suction nitrogen machines, oxygen generators, chemical, and fertilizer industrial gases is amazingly effective in avoiding system explosions due to oxygen in the production process and preventing room interest accidents in hypoxic environments. - 2. The oxygen content in the exhaust gas of the internal combustion engine and the oxygen content in the flue gas is detected to achieve reasonable combustion control and save fuel. - 3.Oxygen content determination is carried out in the atmosphere storage of grains, fruits, vegetables, tobacco, Chinese herbal medicines, tea leaves, dried fruits, etc. - 4. Analysis of oxygen content in ventilators, anesthesia machines, hyperbaric oxygen chambers, infant incubators, and aerospace and diving operations in the medical business. - 5. It is essential experimental equipment for physical chemistry, biology, and other experiments in secondary schools, colleges and universities, and medical schools. 6. It is suitable for determining oxygen content in the meteorological department electrolysis hydrogen production, air separation oxygen production, nitrogen production, and pharmaceutical factory injection quality inspection. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01A6JYD0M | | Brand | Gerneric | | Enclosure Material | Plastic | | Item Dimensions D x W x H | 2.5D x 7W x 12.5H centimeters | | Item Weight | 0.01 Ounces | | Item weight | 0.01 Ounces | | Manufacturer | Gerneric | | Mfr Part Number | CY-12C | | Model Number | CY-12C | | Number of Items | 1 | | Operating Humidity | 90 percent | | Operating humidity | 90 percent | | Product Style | Portable | | Product dimensions | 2.5D x 7W x 12.5H centimeters | | Style | Portable | | UPC | 712994962201 732130965743 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 40 Degrees Celsius | | Upper temperature rating | 40 Degrees Celsius | ## Product Details - **Brand:** Gerneric - **Item weight:** 0.01 Ounces - **Manufacturer:** KY - **Material:** Plastic - **UPC:** 712994962201 732130965743 ## Images ![Portable Oxygen Concentration Content Tester - Image 1](https://m.media-amazon.com/images/I/61vY3HVzE+L.jpg) ## Questions & Answers **Q: buenas tardes, funciona para medir la concentradion de oxigeno en un equipo de concentracion de Oxigeno?** A: Si funciona para medir la pureza del oxígeno entregado por un concentrador de oxígeno **Q: It came with instructions in Japanese!
