(2)Routine maintenance

No parts require periodic maintenance. In case sensor temperature is 800± 5° C or the SO2 concentration in sample gas is high, you should check occasionally that the outlet pipe is not clogged by the precipitation of crystal. Because the sample outlet is at a high temperature, attention should be paid not to suffer a burn.
