Description
testo 335 is the new generation flue gas analyser, specially tailored to industrial applications' requirements. testo 335 can be used for all emission monitoring applications by the operators of industrial furnaces such as processing and power plants, by service technicians for burner/furnace manufacturers, for plant construction as well as for stationary motors. Even spot measurements for up to 2 hours are possible.
Feature:
- max. 3 measurement cells
- Two toxic measurement cells, freely selectable
- High-performance automatically controlled membrane pump
- Logger function
- Parallel ΔP and m/s for flue gas measurement
- 2 measurement range extensions (standard: single dilution with factor 5, option:dilution for all sensors with factor 2)
