烟尘和不透明度监测仪
Bag filter leaks and precipitator problems show up first as a dust or opacity change at the stack. Choose forward scatter for low-dust stacks, down to 0.1 mg/m³, or a transmissometer for opacity across ducts of 0.3–15 m. Response is 10 s or faster. Tell us duct size, gas temperature and expected dust level for sizing.
