Accurately Measure Flammable Gas

Today, there are a variety of sensors used to detect flammable gases. There are also many different flammable conditions, each requiring a specific type of sensor to be accurately measured. When selecting a flammable gas monitor, it is critical that you understand the differences and choose the appropriate sensor for the environment to be measured.

Backup Batteries Emitting Hydrogen

Since batteries are such an effective energy storage medium for almost any backup power system, many industries use backup battery banks for emergency power. The need for gas monitoring occurs while these backup batteries are being charged. Continue reading “Backup Batteries Emitting Hydrogen” »

VOC compounds detectable with the Eagle 2

The Eagle 2 is capable of monitoring most Volatile Organic Compounds (VOC’s). Two types of PID sensors can be used with the Eagle 2, a low range (0 – 50 ppm) sensor and a high range (0 – 2,000 ppm) sensor. With either the low or high range sensor, the Eagle 2 has a PID Relative Response feature, which enables you to change the PID sensor’s response to a different VOC gas on the go.

Difference between Catalytic & Infrared

In detecting combustible gases in oil and gas, petrochemical and other applications, choosing between the two most common gas sensing technologies used for this purpose will be critical in ensuring a safe, reliable and cost effective solution. These technologies are catalytic combustion and infrared. Both have advantages and disadvantages depending on an application s specific needs.

Do Calibration Gases Have a Shelf Life?

Calibration is a vital and necessary step to ensuring the proper performance of any gas detector. The calibration process requires use of a known concentration of test gas, also known as span gas or calibration gas. Use of incorrect or expired calibration gas can result in improper calibration. This can result in unsafe operation, as well as improper diagnosis of instrument malfunction. This article will focus on disposable (non-refillable) calibration gas cylinders for both reactive and non-reactive gases. Continue reading “Do Calibration Gases Have a Shelf Life?” »

Hydrogen Specific Solutions

Hydrogen gas is looked to as a cleaner source of energy for the future. It is also commonly used in many industrial processes. Hydrogen is one of the most explosive gases, and leaking hydrogen cannot be seen or smelled. Continue reading “Hydrogen Specific Solutions” »

Importance of a Sample Draw Pump

By definition a confined space is any space that is large enough and so configured that an employee can bodily enter and perform assigned work, has limited or restricted means for entry or exit, and is not designed for continuous employee occupancy.

Meth Labs Put Responders At Risk

Hazardous events at methamphetamine labs are on the rise, putting law enforcement and emergency response personnel at risk. Fewer than 10% of those arrested for manufacturing meth are trained chemists. Meth laboratory operators or “cooks” usually are individuals who have little or no chemical training and simply learned the formula from other meth cooks or the internet. Continue reading “Meth Labs Put Responders At Risk” »

Monitoring For Inert Spaces

An inert space is one that has been purged with engine exhaust, nitrogen, or other gas mixtures not containing oxygen. It is a common practice on board ships to purge the headspace above petroleum-based product, or in empty product storage spaces to prevent the accumulation of a flammable mixture in the space. For a flammable mixture or fire to exist there are 3 necessary components: fuel, oxygen, and heat or ignition. This is often referred to as the Fire Triangle.

Purge / Test procedure for GX-2003

When new natural gas mains are installed or existing mains removed from service, crews must purge the mains with an inert gas to eliminate the potential hazard of a combustible mixture. The most commonly used and preferred purge gas is nitrogen. After the purge is conducted an upstream valve is opened to allow natural gas to enter. A service valve on the line (usually a needle valve) with a stand pipe or diffuser attached is cracked to allow venting gas or nitrogen to escape. Continue reading “Purge / Test Procedure for GX-2003” »

Refinery Catalyst Dumping Operations

Refineries use large “cracking towers” as a part of their operations. These towers can be approximately 100 feet tall and are filled with a catalyst which assists the conversion of oil into lighter fuels. Periodically, the catalyst must be removed, the tower cleaned out, and new catalyst added. In order to remove the old catalyst, workers must enter and remain inside the tower wearing full protective gear. Continue reading “Refinery Catalyst Dumping Operations” »

Resetting the Calibration Date on the GX-2003

All portable gas monitors need to be calibrated periodically to ensure proper operation. The GX-2003 Model has a feature that allows the user to program a calibration interval that fits their needs, type of usage, and company practice.
