Oxygen Monitor with Remote Sensor


SKU: 99028 Categories: ,


This oxygen monitor has all of the same amazing features of our standard O2 deficiency monitor with the added feature of a remote sensor. This specification allows the sensor to be up to 10ft feet from the monitor, connected by a small wire. This is perfect for use in a freezer or unmanned area, where the sensor would be placed inside the area and you would be able to read the monitor outside at a safe distance. The wire can connect the sensor to the monitor right through a wall.
