Hand-held gas detector and method of gas detection |
摘要 |
A gas detector includes a predetermined amount of a sensor material having at least one optical property which changes as a result of reaction with a target gas and a photometric device operable to measure the intensity of said at least one optical property of the sensor material. The reaction is such that there is a one-to-one relationship between the magnitude of the intensity of at least one optical property and the concentration of the target gas in the gas sample whereby the concentration of the target gas in the gas sample may be determined from the measured magnitude of the intensity of said at least one optical property after the passage of the predetermined volume of gas sample over the given area of sensor material.
