What is the “measuring range” of my gas monitor?
What is the “measuring range” of my gas monitor?
Dave Wagner | Wednesday, October 12, 2011 | Confined Space, Gas Detection Equipment

This question can actually be interpreted in two ways and the obvious one is not usually the interpretation that the user is looking for. In most cases, 0 – 1000 PPM is not the right answer. The measuring range, or range of concentrations detected...

SO2 sensor and Acetylene
Dave Wagner | Wednesday, August 3, 2011 | Confined Space, Gas Detection Equipment, Sensor Technology

Question: Hey Dave, I just heard about a strange confined space monitoring incident where an Itx equipped with an SO2 sensor was alarming for no apparent reason. As it turns out, the sensor was actually picking up acetylene gas from a leak in a cu...

Combustible Gas Detection – Infrared or Catalytic Bead?
Combustible Gas Detection – Infrared or Catalytic Bead?
Dave Wagner | Friday, July 29, 2011 | Sensor Technology

One of the latest and fastest growing trends in gas detection today is the use of infrared sensors for detecting LEL levels of combustible gas. I was engaged in a lengthy debate with a customer this week on whether or not the infrared technology w...
