Understanding Cross Sensitivities Can Help to Keep Workers Safer

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 different options are available to detect gases in a facility. For example, you could collect a sample and have it analyzed with a mass spectrometer to get an exact reading of what is in the... Read More

Why Consider Switching to a Long-Life Oxygen Sensor?

Why Consider Switching to a Long-Life Oxygen Sensor? 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 can affect the accuracy of gas readings. All these external and environmental effects important to consider, but have you ever had to service or replace a gas detector because the... Read More

Where Do Sensor Poisons and Inhibitors Lurk?

Where are sensors poisons and inhibitors lurking? 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 specialized chemicals can all act as sensor poisons or inhibitors to different sensor types. One of the most negatively affected is the catalytic bead LEL... Read More

Why are My SO2 Sensors Failing Early?

Why are My SO2 Sensors Failing Early? “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 which they may seemingly fail early. They may then go on to recover without any user intervention. Measuring Sensor Life Before we discuss why SO2 sensors may fail early, first let’s... Read More

Infrared LEL Gas Sensors – Risk or Reward?

Infrared LEL Gas Sensors – Risk or Reward? 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 calibration while extending instrument run times from hours to months without recharging batteries. The benefits of infrared technology over the industry standard catalytic bead... Read More

The Simple Truth of Calibration Gas Shelf Life

The Simple Truth of Calibration Gas Shelf Life Calibration gas is an important component in ensuring the proper performance of your gas monitors. Regular calibrations promote the accurate measurement of gas concentration values. During calibration, a unit’s installed sensors are to be exposed to their set concentrations of calibration gases. Based on the sensors’ responses, the unit will self-adjust to compensate for declining sensor sensitivity, which naturally occurs... Read More
