Testo Flue Gas Analyzer.
335 Flue Gas Analyzer. NO, CO, CO2, O2, SO2 efficiency.
testo 335 flue gas analyzer, rechargeable battery and calibration protocol included,
equipped with O2
and CO sensor.
testo 335 is the new generation flue gas analyzer, 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.
