NOx testing for gas turbines
Portable flue gas analyser breaks the thousand ppm barrier to make it useful for measuring today's lower emissions limits from gas turbines
Testo's new 350XL is the only portable flue gas analyser with high accuracy measurement of low NOx values Its unique low range sensors make the Testo 350XL ideal for gas turbine exhaust monitoring

Low NOx testing was often at the limit of sensor performance in the past, particularly when measuring below 100ppm NO with sensors that were designed for measuring thousands of ppm.
As emission limits have fallen, the need for more accurate measurements at lower concentrations has increased.
Testo has the answer with new high-accuracy sensors designed to measure in the range 0 to 300ppm with 0.1ppm resolution.
Measurement errors are significantly reduced, particularly at low NO and CO levels, which is important when operating close to consent limits.
The Testo 350 is described as the world's most advanced portable analyser, enabling highly accurate measurement of nine different flue gases, plus temperature, air flow, pressure, humidity, mA, mV, and rpm.
It features an integral sample gas preparation unit, high-performance power pack, large data memory, and weighs less than 4.5 kg - so it is ideal for monitoring in difficult locations.
It is already in use in all major power generation applications, including combined cycle gas turbines, coal and oil fired power stations, waste-to-energy, and nuclear power generation.
