Improper or inappropriate use of the environment may weaken the operating performance of the instrument. For the safest and most effective use of the instrument, please read the following correct operating procedures and safety 2. Please read the manual carefully before any is performed.3. The window and filter membrane of the sensor must be kept clean. If the sensor window is blocked or filtered by the water film, it may result in a reading below the actual gas concentration4. Tho replacement of batteries, maintenance parts and other operations can only be carried out in a environment.5. In order to ensure the safety and the proper use of the instrument, the and maintenance of the instrument can only be carried out by qualified personnel.6. Every day before use please check the accuracy of the instrument in the air, ensure that the measurement error is within the allowable range. If it exceeds the allowable error range, the instrument must be calibrated.

• PROFESSIONAL TESTING - It is a kind of essential safety instrument which can continuously detect the oxygen concentration in the working environment. Professional for testing the oxygen content of the air, with 0-25% oxygen content detection scope.
• EASY - Compact portable size with ergonomic design is easy to use. Adopt menu type interface, battery power real time, making the oxygen gas detector easy to carry, easy to operate.
• ALARM FUNCTION - Our oxygen gas detector with sound, light and vibration alarm alert. Adopts with a good quality electrochemical sensor, it can accurately measure the gas concentration with easy-to-read number shown on the display.
• USAGE ENVIRONMEN - The oxygen gas meter is widely used in metallurgy,power plant, chemical, mine, tunnel, underground pipelines and other places, effective prevention of hypoxia and oxygen poisoning.
• NOTE - Keep the alarm through the mouth , no foreign objects clogging, otherwise it will to not hear the alarm or alarm information identification. Removing and replacing the battery must be performed in a known, no hazardous environment.
