PROBE FOR MEASURING CONTENT OF REACTIVE GAS |
摘要 |
Plaques for rapid retrospective recognition of an overdose of noxious gases are of great importance for industrial protection in the chemical industry. These plaques carry an indicator which undergoes a color change on exposure to the gas. Visual assessment of the indicator is considerably facilitated by subdivision of the indicator surface into a plurality of measuring fields with graded sensitivity by means of different covering membranes. Rapid allocation to a given range of dose is possible by separate or combined visual observation of the individual fields of the indicator. |
