Gas detection solutions for the breathing air gas sensors industry

If you use compressed breathing air it is essential to monitor for contaminants including carbon monoxide (CO), carbon dioxide (CO2) and volatile organic compounds (VOCs) as well as oil mist and water vapour. Some people spot-check their compressed air quarterly using colorimetric tubes, but it is safer to test the air continuously. If you are operating or servicing equipment containing fluorinated greenhouse gas (F gas) in refrigeration, air conditioning and fire protection systems you need to adhere to requireme...

High quality gas sensor solutions for mining industry

Fast, accurate and reliable measurement of CH4. The extraction of coal releases methane gas, which can mix with the air in a mine to form a hazard due to its flammability. Ventilation with fresh air from the surface is used to dilute the methane and reduce the risk of explosion. Monitoring of the methane content of the stale air exiting the mine allows the amount of ventilation to be controlled. Although our sensors are not ATEX approved for use in potentially explosive atmospheres they are suitable for monitoring...

High quality gas sensor solutions for landfill

State-of-the-art systems enabling easy monitoring of CO2 and CH4 gases. Capped Landfill Sites produce a range of gases, mostly methane and carbon dioxide. Legislation requires that these gases are safely removed from beneath the cap to avoid a physical explosion due to the build-up of pressure beneath the cap. Safe disposal usually entails burning such as flare stacks, internal combustion engines or by processing to produce Methane gas fuel. For large sites with access to power distribution infrastructure...

High quality gas sensor solutions for modified atmosphere packaging

Extending the shelf-life of perishable foods. Changing the atmosphere inside the packaging the shelf life of many fresh products can be extended. For example, by decreasing the amount of oxygen and increasing the carbon dioxide the shelf life of many fruits may be significantly improved. Using various gas combinations it is also possible to slow down the growth of bacteria and extend the shelf-life of other perishable foods like meat, fish and vegetables.

Gas Detection Solutions for Sour Gas

The sour (H2S) content of hydrocarbon fields worldwide is increasing, and many natural gas fields have very high H2S – sometimes in excess of 50%. H2S is extremely dangerous because, although people can smell it at low levels (about 5 ppb) it does not smell much worse at the exposure limit value of 10 ppm or at potentially fatal levels in excess of 100 ppm. Therefore smell is an unreliable means of determining dangerous levels. Existing H2S point sensors are maintenance intensive, slow to respond and...

High quality gas sensor solutions for Controlled Atmosphere (CA) storage

Precise regulation of O2, CO2 and N2 concentrations. A controlled atmosphere is an agricultural storage method in which the oxygen, carbon dioxide and nitrogen concentrations are regulated. The humidity and temperature are also controlled, resulting in a slow loss of quality during prolonged bulk storage of products such as apples, pears, grains, legumes, etc.

High quality gas sensor solutions for building and IAQ

Precise measurement of air quality. The carbon dioxide content of room air gives a measure of the air quality, especially as it relates to the health and comfort of the people occupying the building. Air quality can be adversely affected by increased levels of carbon dioxide, carbon monoxide, volatile organic compounds (VOCs), particulates, or bacteria. Increased ventilation reduces the level of all of these unwanted contaminants. Measuring the CO2 concentration provides an economical way of ensuring that there...

High quality gas sensor solutions for total organic carbon (TOC)

Minimising costs through measurement of CO2 concentration. Both water suppliers and water users need to know the quality of the water they are supplying, using and disposing of so as to minimise their costs. One measure of water quality is the organic carbon content (TOC). TOC is measured by oxidising the organic carbon to produce CO2 which is then measured and the value converted into a TOC measurement. Edinburgh Sensors supply sensors to measure the CO2 concentration produced by oxidising the organic carbon in...

Wet gas monitoring for refineries

Thermal mass flow meters provide excellent measurement capabilities in dry gas flows. They have proven durability, accuracy, and repeatability. However, thermal flow meters are sensitive to liquid droplets in a wet gas stream. For a thermal flow meter to work accurately in a condensing gas environment, the probe must be placed far enough downstream so that the entrained water has condensed onto the pipe wall. In a very wet environment, any condensing liquid (commonly referred to as mist or fog) contacting the...
