It excels at measuring oxygen concentrations of 10 vol% or less.
A highly functional oxygen concentration meter that utilizes low power consumption circuit design technology.
A high-performance oxygen sensor is used to achieve a resolution of 0.01%.
There are two types of sensors to choose from.
Stainless steel case separated type sensor (approximately 3 m) is ideal for concentration measurement inside a container.
Curl cord separated type sensor (approximately 1.75 m) is suitable for oxygen measurement in containers and concentration measurement in tubes.
It outputs 0 to 25 vol% linearly at 4 to 20 mA against the measured concentration, and can be linked with a device that manages low-concentration oxygen.
