An oxygen warning device consisting basically of an oxygen galvanic cell was given practical tests to simulate its application in scuba mixed gas equipment as an indicator of low oxygen percentage. Two improved cell types were also tested. While the hardware of the original device was not considered practical for direct application in the scuba equipment, the cells were found to perform satisfactorily in terms of following the predicted output curve under most simulated conditions. Minor inadequacies which hold promise of correction were found in the cells including zero stability, time of reaction, response to gross wetting, and erratic behavior in presence of carbon dioxide.
