NOx testing for gas turbines

Testo reckons its new 350XL is the only portable flue gas analyser with high accuracy measurement of low NOx values.

Testo reckons its 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 parts per million.

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 the world's most advanced portable analyser, enabling highly accurate measurement of nine different flue gases, plus temperature, airflow, 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 4.5kg, 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.
