Low concentration oxygen concentration meter JKO-O2 Ver.3
Ichinen Manufacturing Co., Ltd.
About This Product
This is a low concentration oxygen meter that specializes in oxygen concentrations of 10vol% or less. This is the low concentration compatible version of the high-performance oxygen concentration meter JKO-25Ver.3 series that takes advantage of low consumption circuit design technology. By adopting a high-performance oxygen sensor for measuring low concentration oxygen, we have achieved a resolution of 0.01%. It outputs 0-25vol% of the measured concentration linearly at 4-20mA, so it can be linked with devices that manage low concentration oxygen. This product can be used for a wide range of purposes, from safety management to concentration monitoring.
■Product features
- Adopts 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.
-The resolution is 0.01%, which allows you to check values that are one digit lower than normal oxygen monitors.
・Equipped with arbitrary setting of alarm value, buzzer ON/OFF, and analog output, it can be used for various purposes.
・JKO-O2LJD3 can continuously measure the oxygen concentration in piping by attaching an in-line jig/BF-JK (optional) to the sensor tip.
