Compact Digital Gas Concentration Meter (Bromine) Model Number MC5700-200MJ
By adopting a potentiostatic electrolysis method sensor, stable measurement readings are possible.
● By measuring only one gas per unit, we have made it possible to measure low concentrations (ppb level) that were previously difficult. ● It features an integrated sample pump with a rechargeable lithium-ion battery, allowing for continuous use of up to 8 hours. ● It has an automatic data saving function and allows for downloads in CSV format.

Applications/Examples of results
■Measurement Principle This measuring device continuously collects sample gas using a built-in pump and sends it to the detector. When the sample gas, which has diffused and been absorbed into the electrolyte through a gas-permeable membrane, is oxidized by potentiostatic electrolysis, a weak electrolytic current is generated and amplified, which is then displayed as the concentration of the target gas. As shown in the figure above, it consists of a detector (electrolytic cell) equipped with a gas-permeable membrane, working electrode, and counter electrode, along with a potentiostatic power supply and amplifier.
