WHAT YOU NEED TO KNOW ABOUT SENSOR POISONS AND INHIBITORS
WHAT YOU NEED TO KNOW ABOUT SENSOR POISONS AND INHIBITORS
Ryan Thompson | Tuesday, November 5, 2019 | Gas Detection Education, Sensor Technology

The sensors inside your personal gas detector are meant to be exposed to toxic, corrosive, and explosive gases, but that doesn’t mean they are infallible. Chemicals and vapors from everyday cleaners and lubricants and other specialized chemicals c...

Why do I See Negative Readings on my Gas Monitor?
Why do I See Negative Readings on my Gas Monitor?
Dave Wagner | Wednesday, September 18, 2019 | Sensor Technology

This is a question customers ask all the time. Why do you sometimes see negative readings on your gas monitor? All electrochemical or catalytic bead gas sensors can be prone to both positive and negative drift due to environmental factors like cha...

Understanding Cross Sensitivities Can Help to Keep Workers Safer
Understanding Cross Sensitivities Can Help to Keep Workers Safer
John Onuska | Thursday, May 24, 2018 | Sensor Technology

Cross Sensitivity in the Workplace  - Toxic, combustible, and asphyxiant gases pose some of the greatest threats to workplace safety. In some cases, you may be unsure which gases could be present in your work environment. Fortunately, many differe...

Why Consider Switching to a Long-Life Oxygen Sensor?
Why Consider Switching to a Long-Life Oxygen Sensor?
Tae-Yeon Won | Thursday, March 22, 2018 | Sensor Technology

There are many ways that sensors in a gas detector can go bad. You might drop an instrument and damage the sensor inside.  You might be in an environment where the ambient gas can poison sensors. You might be in a high humidity environment that ca...

Why are My SO2 Sensors Failing Early?
Why are My SO2 Sensors Failing Early?
Michelle Hammons | Thursday, November 30, 2017 | Gas Detection Education, Sensor Technology

“Why are my SO2 sensors failing early? Wait … now they're fine. What’s going on?” It’s a scenario we’ve heard numerous times. While sulfur dioxide (SO2) sensors are typically expected to last between two and five years, there are situations in whi...

Infrared LEL Gas Sensors – Risk or Reward?
Infrared LEL Gas Sensors – Risk or Reward?
Dave Wagner | Monday, August 7, 2017 | Gas Detection Education, Sensor Technology

What are the limitations of infrared LEL gas sensors? There has been a lot of recent discussion about the benefits of infrared LEL gas sensors for the oil and gas industry. There have even been claims that these sensors operate for years without c...

Are All Carbon Monoxide Sensors the Same?
Are All Carbon Monoxide Sensors the Same?
Gregg Bako | Monday, February 27, 2017 | Sensor Technology

The short answer is – no, all carbon monoxide (CO) sensors are not the same. CO sensors are found in gas monitors used by workers conducting their jobs in environments where toxic CO gas might be present. With CO being a result of incomplete combu...

No Calibration Required?
No Calibration Required?
Industrial Scientific | Friday, January 27, 2017 | Gas Detection Education, Sensor Technology

Gas Detectors can be difficult to maintain, especially when you need to perform frequent instrument calibration. Calibration is not a particularly challenging or time-consuming process. It only requires a few minutes and a few button presses. The ...

Why do LEL sensors drift so much?
Why do LEL sensors drift so much?
Dave Wagner | Friday, September 20, 2013 | Sensor Technology

In recent weeks, I have addressed many questions as to why catalytic bead LEL sensors seem to drift so much, particularly in the hot, humid summer weather. To understand the reason for the drift, you must understand the operating principle behind ...

Do LEL sensors have a cross interference to CO2?
Do LEL sensors have a cross interference to CO2?
Dave Wagner | Friday, September 30, 2011 | Gas Detection Education, Gas Detection Equipment, Sensor Technology

A career firefighter and great friend of Industrial Scientific shared a video clip with me this week.  Firefighters in Phoenix, AZ were called to an incident at a fast food restaurant after a worker had collapsed walking up the stairs from the bas...

What’s all this “pentane equivalent” gas stuff about anyhow?
What’s all this “pentane equivalent” gas stuff about anyhow?
Dave Wagner | Tuesday, August 16, 2011 | Gas Detection Education, Sensor Technology

Recently I have fielded more questions and had more inquiries about obtaining and using “pentane equivalent” calibration gas than ever before.  So what is all this “pentane equivalent” gas stuff about anyhow? The notion of “pentane equivalent” or ...

SO2 sensor and Acetylene
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...
