A low-concentration oxygen meter that excels at measuring oxygen concentrations below 10 vol%! Suitable for scientific experiments and culture tests.
This is a low-concentration version of the high-performance oxygen concentration meter JKO-25 Ver.3 series, utilizing low-consumption circuit design technology. By adopting a high-performance oxygen sensor for low-concentration oxygen measurement, it achieves a resolution of 0.01%. It outputs a linear 4-20mA signal for measurement concentrations of 0-25 vol%, allowing integration with devices that manage low-concentration oxygen. This product can be widely used for safety management and concentration monitoring. 【Features】 - Utilizes a sensor compatible with low-concentration oxygen, achieving a resolution of 0.01% - Calibration method is one-touch automatic, and calibration gas can be set arbitrarily - Resolution is 0.01%, allowing confirmation of values one digit lower than standard oxygen monitors - Equipped with customizable alarm settings, buzzer ON/OFF, and analog output, making it suitable for various applications - The JKO-O2LJD3 can continuously measure oxygen concentration in piping by attaching an inline fixture/BF-JK (optional) to the sensor tip *For more details, please download the PDF or contact us.

| Model number | overview |
|---|---|
| JKO-O2LJD3 | The approximately 1.7m curly cord attached sensor unit has a threaded tip, allowing for the measurement of oxygen concentration in a sealed environment by providing screw holes in the groove box or chamber. Using the separately sold inline fixture BF-JK, oxygen concentration measurements can be performed in tubes or piping. |
| JKO-O2LD3 | Since the sensor is protected by a robust stainless steel housing, it can be safely used in environments where the sensor unit must be suspended. This type is optimal as a portable oxygen meter. |
