SO2 low kit unheated

Order-Nr.  0563 1251

  • High degree of measuring accuracy

  • Quick, convenient short-term measurements

  • No electricity supply needed

  • Easy to handle at the measuring point and during transport

Use the kit with SO2 low sensor and special SO2 low gas sampling probe for measuring low SO2 values following flue gas after-treatments (e.g. scrubbers). SO2 measurement enables you to ensure the legally compliant operation of coal-fired power plants, waste incineration plants and large engines. Particularly convenient: the efficiency of the reduction of SO2 concentrations is calculated directly in the testo 350 flue gas analyzer (please order separately).
