95-99% Calcium Hydroxide 1305-62-0 Hydrated Lime

features and advantage : The multi-channel fiber optic gas detector combines the advantages of fiber optic and TDLAS technologies, which are specifically reflected as follows: Excellent gas selectivity, the detection process is not easily interfered by other gases; All-optical detection means can be used safely in explosive environments; The optimized design of the miniaturized fiber optic gas probe has a compact structure and high coupling efficiency; it is connected to the host through an all-fiber fiber, which has excellent long-term stability; Using a near-infrared narrow-band tunable light source, one host can simultaneously detect methane gas concentrations at multiple measurement points, significantly reducing costs; Fast detection speed, high sensitivity and long service life; The optical fiber used is ordinary single-mode optical fiber, which is compatible with existing optical fiber communication networks to build detection systems. apply forSuitable for various point and quasi-distributed monitoring fields of methane gas: Natural gas pipeline network leakage monitoring Online intelligent monitoring of oil and gas pipelines Coal mine safety production Natural gas leakage detection in urban underground pipeline corridors
