How can we help identify natural gas leaks when H2 is added?

TBM and THT are the most common odorants used to make odourless, natural gas smell so that people know when there is a gas leak. However, these odorants need to be monitored and controlled to maintain their effectiveness. Due to various “power to gas” initiatives, more and more H2 will be added to natural gas. For this reason, a gas measurement device with high-performance gas sensors and no H2 interference is required.  So, we are pleased to provide you with the Sensorix TBM 50 and the Sensorix THT 100 low H2, our perfect solution for the detection of mercaptans and THT in natural gas with added H2.

About the Sensorix TBM 50

The Sensorix TBM 50 detects mercaptans with zero cross sensitivity towards H2, CO, H2S, and THT and is ready for use in H2 containing natural gas (“power to gas”). Its performance is demonstrated by the following characteristics:

  • The Sensorix TBM 50 gas sensor has excellent repeatability (standard deviation of sensitivity = 0.5 % for 10 consecutive measurements at 10 mg/m³ TBM);
  • It shows excellent baseline stability from -10 to 40°C and in changing humidity (<0.1 mg/m³);
  • Last but not least, its unbiased operation will increase the battery life of your portable instrument.

You can find detailed information in the datasheet.

About the Sensorix THT 100 low H2

The Sensorix THT 100 low H2 is the perfect solution for power-to-gas applications due to its performance features:

  • It has a very low H2 interference (THT signal only 1 mg/m3 in 20% Hydrogen);
  • The sensor has no H2S cross interference;
  • It requires 300 mV bias.

You can find detailed information in the datasheet.

All sensors are available in various standard formats – 4S, 7S, Mini, Classic, and Smart, as well as in customer-specific mechanical adaptations.
