What is a GMI gas detector?
Teledyne Gas Measurement Instruments Founded in 1947, Teledyne GMI is a world leader in the design and manufacture of high quality and innovative portable gas detectors, specifically designed for the oil and gas, chemical and shipping industries world-wide.
Which gas can multi gas detector GMI PS200 test?
#1 – The PS200 from GMI is a multi-gas detector, capable of detecting levels of LEL, oxygen (O2), carbon monoxide (CO) and hydrogen sulphide (H2S).
What is portable gas detector?
Unlike fixed gas detectors, which permanently monitor a designated area, portable gas detectors are mobile devices used by personnel to provide pre-entry gas level checks. Each portable device will test gas levels in an area to ensure it is safe for human entry.
What is a pumped gas detector?
GMI PS200 Pumped Gas Detector LEL,H2S,CO,O2 Detecting and displaying up to 4 gases simultaneously, PS200 is suitable for a host of applications in a variety of industries. The PS200 can be configured to detect a combination of Methane, Oxygen, Carbon Monoxide, Hydrogen Sulphide, as well as other flammable gases.
What is a 4 gas detector?
A 4-gas detector is a gas monitor that is intended to detect combustible gas. Unlike a smoke or carbon monoxide detector, this machine can identify various concentrations at the same time.
What is 100% LEL?
One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas is at its lower flammable limit. The relationship between percent LEL and percent by volume differs from gas to gas. The example below demonstrates the flammability of Methane (Natural Gas) in Air.
What is the LEL?
The Lower Explosive Limit (LEL) is the lowest concentration of a gas or vapour that will burn in air. The Lower Explosive Limit (LEL) varies from gas to gas, but for most flammable gases it is less than 5% by volume.
What is LEL & UEL?
Lower explosive limit (LEL): the lowest concentration of gas or vapour which will burn or explode if ignited. Upper explosive limit (UEL): the highest concentration of gas or vapour which will burn or explode if ignited. From the LEL to the UEL, the mixture is explosive.
What is LEL level?
The term L.E.L. stands for Lower explosive limit of a combustible gas or vapor. It’s the lowest level a gas can ignite in air in the presence of an ignition source. Conversely, U.E.L (upper explosive limit) is the maximum level in air that a gas may ignite.
Why choose Teledyne GMI?
Teledyne GMI continues to invest heavily in research and development, a high percentage of which is spent on the development of state-of-the-art instruments and new sensing technologies. Teledyne GMI is ISO 9001:2008 approved, BSI registered and a member of the council for gas detection and environmental monitoring (COGDEM).
What is the GMI leaksurveyor?
The GMI Leaksurveyor combines quality, ruggedness and advanced GMI Technology in a user friendly, portable gas detector. The internal semiconductor sensor with fast response and high sensitivity enables leakage surveys to be performed and distribution leaks to be quickly found.
What is a thermal conductivity detector?
Our TCD is equipped with user-replaceable filaments, so it can be quickly returned to service in the event of a burn-out. Because it detects all molecules, the Thermal Conductivity Detector is commonly used for fixed gas analysis (O2, N2, CO, CO2, H2S, NO, etc.) where the target analytes do not respond well on other, more sensitive detectors.
