Detailed information
-
Equipped with a long-life oxygen sensor Equipped with a long-life oxygen sensor with an average lifespan of 3 years in the atmosphere. It offers excellent reliability and can be used stably for a long time. The measurement range achieves 0-100 vol% oxygen and can also detect high concentrations of oxygen. *The lifespan of the oxygen sensor may vary depending on the usage environment. This does not guarantee the sensor's lifespan.

Powerful alarm system The JKO-25Ver.3 is equipped with a two-stage alarm (AL1, AL2), alarm buzzer, high-brightness LED alarm lamp, alarm output (relay dry contact), and analog output of 0-1V, ensuring that any potential oxygen deficiency alarm reliably alerts those nearby to the danger.
Line up（9）
| Model number | overview |
|---|---|
| JKO-25S3 | Standard model with built-in sensor. Suitable for measuring oxygen concentration around the measuring instrument. It can be easily carried, making it suitable for temporary workplaces and measuring oxygen concentration in glove boxes, as well as in workplaces and tunnels where there is a risk of oxygen deficiency. It can be used in a wide range of applications, both stationary and portable. |
| JKO-25W3 | Stationary set with sensor unit, 10m sensor cable, and wall mount bracket. Its compact and lightweight design allows for installation in factories, warehouses, clean rooms, laboratories, tunnels, etc., without the need for extensive external construction, making it easy for anyone to install. |
| JKO-25LJ3 | The sensor with approximately 1.7m coiled cord has a threaded tip, allowing for the measurement of oxygen concentration in sealed environments such as glove boxes and chambers, or using separately sold inline fixtures to measure oxygen concentration in tubes and piping. |
| JKO-25L3 | The sensor unit is protected by a robust stainless steel housing with a moderate weight, allowing for stable detection even in environments where the sensor must be suspended, such as manholes, tanks, silos, wells, vertical holes, and various pits. Additionally, all models of JKO-25Ver.3 feature a disconnection display function. |
| JKO-25MT3/ML3 | It is designed with a tube fitting or elbow, or bamboo shoot type. It can be easily connected to tubes, making it suitable for maintenance of HOT (Home Oxygen Therapy) oxygen concentrators and measuring residual oxygen concentration in nitrogen generation devices. It is suitable for experiments and laboratories through tube lines. |
| JKO-25SD3 | This is the power adapter-driven type of JKO-25S3. It comes with a wall mount bracket. |
| JKO-25WD3 | This is the power adapter-driven type of JKO-25W3. |
| JKO-25LJD3 | This is the power adapter-driven type of JKO-25LJ3. It comes with a wall mount bracket. |
| JKO-25LD3 | This is the power adapter-driven type of JKO-25L3. It comes with a wall mount bracket. |
