Oxygen level indicator

Will this sensor only sense oxygen or it will indicate the level of oxygen too? If not do you have such instruments?

We have all kinds of instruments and sensors to detect oxygen levels. Give us a call at (386) 872-7668 and a sales engineer. They will be glad to take your requirements and make a recommendation!
