Dissolved oxygen meters are analytical instruments that are used to measure the amount of oxygen dissolved in a liquid sample. Search by Specification | Learn More about Dissolved Oxygen Meters

Gas detectors and gas sensors interact with a gas to initiate the measurement of its concentration. The detector or sensor then provides output to an instrument to display the measurements. Search by Specification | Learn More about Gas Detectors and Gas Sensors

...or oxygen) and ignited. In gas-detection systems, the amount of gas present is specified in terms of % LEL: 0% LEL being a combustible gas-free atmosphere and 100% LEL being an atmosphere in which the gas is at its lower flammable limit...
