    Abstract

    On the high mountain the partial pressure of oxygen becomes low in porportion to the atmospheric pressure with the altitude. It is important, therefore, for the health and safety of mine workers working in the underground mine to know the accurate and correct oxygen content in the environmental atmosphere. However, the availability of portable oxygenmeter on the high mountain, hitherto, has been hardly concerned about. In this paper the indication accuracy of some galvanic cell type portable oxygenmeters under the low atmospheric pressure was studied in a low pressure testing apparatus which imitated the high altitude conditions up to 3000m. The tests in the laboratory and on the field revealed that the indication accuracy of oxygenmeters hithertofore in use were not enough for the use on high mountain, the main reason being the inadequacy of membrane characteristics of galvanic cell used in the oxygenmeter. The new oxygenmeter modified with an improved membrane works fairly good in the scope up to 5000m high and the indications coincide with the standard oxygen concentration calculated on each altitude.
