For long-term measurement of medical gases (oxygen) concentration, as well as for physical and chemical experiments and cultures!
The functionality of JKO-25 Ver.3 remains unchanged, and we have upgraded it to meet the requests of many users. 【Additional Features】 - Equipped with an auto-span adjustment function, eliminating the need for manual operation (optional)! - Displays maintenance schedule date (optional)! - With the complete barometric pressure correction function, it prevents false alarms caused by typhoons, etc. (the barometric pressure sensor is built into the main unit and is optional)! 【Functions carried over from JKO-25 Ver.3】 - Can be used in a full range of oxygen concentration from 0-100 vol%, allowing for high-concentration oxygen measurement. - Real-time oxygen concentration can be checked on a large LCD. - Compact and easy-to-hold shape. Soft case available as an option. - Alarm concentration settings can be configured in two stages, with options for upper and lower limits. - Easily identifiable electronic buzzer sound during alarms. - Alarm notifications with two red LEDs. - Option to hold the alarm or automatically reset. - External alarm output can control devices such as rotating lights and solenoid valves. - Analog output of 0-1V can be used to extract oxygen concentration externally. *For more details, please download the PDF or contact us.*

Line up（5）
| Model number | overview |
|---|---|
| JKO-ASD3 | This is a standard model with a built-in sensor. It is suitable for measuring the oxygen concentration around the detector. It can be used as both a stationary and portable device. |
| JKO-AWD3 | This is a stationary oxygen meter that comes with a sensor box and a 10m sensor cable. It can be installed in various locations such as factories, warehouses, clean rooms, laboratories, and tunnels. It can be easily installed by anyone using the included wall-mounted bracket. It is the ideal type for countering oxygen deficiency. |
| JKO-ALD3 | Since the sensor is protected by a robust stainless steel housing, it can be safely used in environments where the sensor part must be suspended, such as manholes, tanks, silos, wells, vertical holes, and various pits. It is the optimal type for portable oxygen meters. |
| JKO-ALJD3 | The sensor part, equipped with an approximately 1.7m coiled cord, has a threaded tip, allowing for the measurement of oxygen concentration in sealed environments by providing a threaded hole in groove boxes or chambers. Using the separately sold inline fixture BF-JK, oxygen concentration measurements can be performed in tubes or piping. |
| JKO-AML3/JKO-AMT3 | Equipped with a tube fitting, it allows for easy connection of tubes. It is the ideal type for maintenance of oxygen concentrators for home oxygen therapy (HOT) and measuring residual oxygen in nitrogen generation systems. ML3 type: elbow-type tube fitting, MT3 type: bamboo shoot-type tube fitting. *This product is not a medical device. Do not use it on the human body. |
