The Testo 335 is a flue gas analyser tailored to industrial applications, from processing and power plants to burner and furnace servicing and stationary motors. It supports two freely selectable toxic sensors and measurement range extensions for high gas concentrations.
KEY BENEFITS
- Two freely selectable toxic sensors: CO, COlow, NO, NOlow, NO2, SO2
- Measurement range extensions for high CO concentrations
- Optional parallel differential pressure or flow measurement
- Powerful diaphragm pump with constant flow (-200 to +50 hPa)
- Gas sampling hose up to 7.8 m long

Industrial flue gas analysis with flexible sensor options
The Testo 335 is a flue gas analyser specially tailored to the requirements of industrial applications. It suits emission monitoring for operators of industrial furnaces such as processing and power plants, service technicians for burner and furnace manufacturers, plant construction and stationary motors, with spot measurements possible for up to two hours.
Two freely selectable toxic sensors (CO, COlow, NO, NOlow, NO2, SO2) and two measurement range extensions allow measurement to continue despite high CO concentrations, while a powerful, automatically controlled diaphragm pump maintains a constant flow across a wide pressure range.
With industrial probes rated up to 1000 C, a logger function, graphic sensor calibration data and accuracy approved to EN 50379 Part 2, the 335 is built for demanding professional use.
