The following parameters were determined. <br />Accuracy- How closely test gas concentration, as measured by the detector, agrees with the <br />actual gas concentration. <br />Bias- Whether the method consistently over-estimates or under -estimates gas concentration. <br />Not applicable to qualitative detectors. <br />Detection Time- Amount of time the detector must be exposed to test gas before it responds. <br />Fall Time- Amount of time that passes before the detector returns to its baseline reading after <br />test gas is removed. <br />'Radian Corporation.
