Gas detection in the oil & gas industry
There are multiple hazards when processing oil and gas, from combustibility to harmful and deadly gases. Gas detection is critical to protecting people and property from these hazards.
We offer the most comprehensive line of field-proven gas detection products for the oil and gas industry. Our gas detection systems are designed to withstand the harshest environments while performing reliably and with a lower lifetime cost.
Gas detection in offshore exploration and production
Offshore exploration and production is often undertaken in extreme environments. Climatic conditions team up with combustible and toxic gases to create working conditions that can go from safe to dangerous in the blink of an eye.
Our gas detection products for offshore exploration and production are as tough as the people they’re designed to protect. We are the leading supplier to the Taranaki oil & gas industry and have a 30-year history of providing reliable equipment that stands up to the corrosion, extreme weather and other conditions found on offshore rigs.

Gas detection in the liquid natural gas (LNG) industry
The risk of gas leaks and subsequent explosion is present in every operational step of LNG production, from compression and odourisation to storage and distribution. The high flammability of the LNG makes reliable gas detection a critical priority.
Our gas detection systems are ideally suited to LNG facilities. Our range of products with over 20 years’ experience in LNG facilities helps ensure there are no interruptions to production and that people and property remain protected.

Gas detection in the liquified petroleum gas (LPG) industry
Highly flammable, LPG requires stringent monitoring during every step of its production, storage and transportation. There is no margin for error and the risk of harm to people and property cannot be underestimated.
Our gas detection systems have the required functionality and reliability to keep LPG facilities and workers safe. We also bring experience – our gas detection systems have equipped more than 100 LPG facilities around the world.

Gas detection in the petrochemical industry
Derived from either petroleum or natural gas – both highly combustible – petrochemicals involve significant manufacturing risks. Determining the right gas detection system is dependent upon on the process and the product being manufactured.
Our gas detection systems and our depth and breadth of experience are the best in the industry. Our proven sensor technology allows us to provide a solution for the most demanding petrochemical applications.

You can trust our expertise and rely on our service
We know your No. 1 priority is to protect your people and your plant. What you don’t want is to fail legal or OSH requirements, have a staff member harmed or be prosecuted for an accident. With an increasing focus on health and safety in the workplace, it’s more important than ever.
We understand the unique requirements of Central and Local Government. You don’t need the hassle and risk of gas detectors that are expensive, problematic, unreliable, prone to sensor failures, require too much servicing, or have recurring problems. We’ll provide you with gas detectors that are…
FAQs
Frequently Asked Questions
Depending on how they’re used there’s no reason a high-end instrument shouldn’t last 6 years. With low-cost instruments ($1,000) you will reach a stage where the gas detector is still fine but the cost of keeping it in the field is greater than buying a new one. For example, replacing two sensors and calibrating the unit could cost $1,100 but a new instrument is around $1,000.
All our instruments are IP rated (ingress protection rated). Typically IP67, which is very high. Gas detectors rated to IP67 must be dust tight and withstand immersion in water up to 1 metre deep for 30 minutes.
Solid particle protection level 6: No ingress of dust; complete protection against contact.
Liquid ingress protection level 7: No ingress of water in harmful quantity when the unit is immersed in 1 metre of water for 30 minutes.
See https://en.wikipedia.org/wiki/IP_Code for more info.
We can provide you with options from the top end to the basic. With our iNet InSite programme you get all the bells and whistles, all the basics like data-logging, bump testing and calibration; plus you get reports on instrument usage such as…
- Instrument in alarm condition and alarm ignored.
- Instrument turned off whist in alarm condition.
- iNet Control.
iNet Control is a web-based application accessible from any PC web browser that allows you to configure and manage your gas detector fleet. It gives you practical insights into your gas detection program using trends, performance metrics and custom reports.
Yes. Calibrations done by us at our premises cost $140 per instrument.
Yes. All our instruments are independently tested by authorities such as ATEX, IECEx, ANZEx, UL, CSA and many more, usually country dependant.
New Zealand recognises the first 3. The gas detector has a sticker attached to it referring to the certification authority and its rating. Many have more than one authority rating, often 3.
Depending on sensor configuration and the number of gas detectors being purchased, the price varies from $950 to $4,500. The MX4, our most popular instrument, sells for $950 to $1,150 depending on configuration.
We process 95% of instruments the day they arrive. It does depend a little on the volume of work but we strive for same day turnaround whenever possible.
You would typically be looking at our MX4, MX6 and single gas models depending on the application, etc.
Yes. You would typically be looking at our MX4 model.
Yes. You would typically be looking at our MX4 model.
Yes, most definitely. On delivery we like to spend time with the users taking them through the basic use of the gas detector. We also like to spend time with the users of the docking stations teaching them how to use them. Industrial Scientific also has very good online training modules.
Case study: 36% cost saving
After concerns at the cost of keeping their instruments in the field, a new client asked Entec to present a 3-year full-service lease. The cost of the lease was $14,000 p.a. and they were currently spending $22,000. Hence they signed up for a 3-year lease. They were referred to Entec by two sites near them that are using our equipment and are very happy with the product and service.
Case study: Over the ditch and far away
A company involved in checking for methyl bromide on export logs approached us for quotes. They were using an opposition product that was proving unreliable and difficult to get serviced in a reasonable timeframe because they had to go to Australia for service. Our gas detection instruments had a higher initial purchase price, but with a quicker and less expensive New Zealand service option the lifetime cost equation stacked up and they changed over to us.
Case study: Sensor issues
A company with a lot of hydrogen on their site was having difficulty with their carbon monoxide (CO) sensors because of the cross-sensitivity between the hydrogen (H2) and the carbon monoxide (CO) sensors. We demonstrated to them our CO sensor with H2 null feature. This completely solved the issue and they now buy their gas detection instruments from us.
Case study: Expensive repairs & poor service
A larger oil company was sick of expensive repairs and poor service, purchased a number of instruments from us. We monitored the cost of repairs for these instruments and based on the information we collected we offered them a lease that covered both repairs and calibrations. This customer now has a large fleet of instruments and bump test stations.
