Calibration Gas

Save time and money on your calibration / span gas

Research shows that for maintenance, repair and operating (MRO) a staggering 55% of spending is wasted. Surprisingly the majority of these costs are a result of unnecessary administration and operations costs, rather than product costs.

When you have too many suppliers, each with their own product lines, you spend too much time procuring and processing orders. This results in a hugely inefficient and costly buying process.

Frequently Asked Questions

Q: Are the cylinders recyclable?
A: Yes, these can be recycled as normal, alternatively, you can send empty cylinders to a scrap metal agent, they can be worth up to approximately $2 / cylinder.

Q: How can I dispose of used cylinders?
A: A hole can be drilled in the cylinder once empty; the cylinder is then just scrap metal. We can supply a recycle tool (see website) which punctures a hole in the middle. Martek supply low cost, simple recycling tools to render the cylinders ready for recycling.

Q: Can you supply 99.9999% nitrogen for the calibration of inert gas systems?
A: Yes, we can supply this gas in a 34 litre (water capacity) cylinder world-wide.

Q: What type of valve connectors do the cylinders use?

A: Martek supply two global standard regulators, these are model numbers 713 and 715.

Q: Which regulator do i need?
A: 17 litre steel & 34 litre steel cyclinders require the 713 regulator while 34 litre aluminium, 58 litre aluminium & 103 litre steel cyclinders need the 715 regulator.

Q: Where are your stocks held?

A: We have an expanding international stocking policy and currently we have stocks of gases in the following locations: UK; UAE; CHINA; SINGAPORE and the USA.

Q: How long does it take for our order to get to the ship's agent?

A: This is dependent on where your ship is in the world. If your vessel is calling at a port where stocks are held, despatch can be arranged within hours. If the gases need to be air freighted then the delivery from a stocking centre will take between 24 hours and 1 week for the most inaccessible regions. You will of course be advised of delivery times at the point of order.

Q: Why can you ship calibration gas quicker and easier than other suppliers?
A: Firstly, we have built a global supply chain management system to anticipate the demands of the dynamic maritime market and secondly we have huge experience of shipping hazardous gases worldwide so we can operate a lean process of order processing.

Q: Are your cylinders suitable for portable gas detectors?

A: Yes - Most modern portable gas detectors are designed to monitor as multiple gases and we provide a range of quad gases for the accurate calibration and testing of portable multi-gases.

Q: How do I apply the gas onto the sensor heads?

A: The manufacturer of your instrument should provide calibration instructions and an adapter to allow you to do this. With every regulator supplied with the calibration gas, we will also give you flexible tubing, this will 'push-fit' onto a range of manufacturer's adapters.

Q: How do i know your gases are the same quality as what I am currently buying?

A: We are going through ISO9001:2008 and we are now supplying some of the key OEM's in gas detection following extensive testing. We have 13 years experience and are a PRIME manufacturer of speciality gases to major oil and gas companies worldwide.

Q: What's the benefit for my company of switching our business to the fastcalgas?

A: Converting to fastcalgas will give you a reliable world-wide calibration gas service, due to strategic (and expanding) stocks around the world. The service is designed specifically for the marine industry where we endeavour to make whole process simple and pain free. You can immediately order online against a firm stock availability and competitive delivered price, and with all hazardous cargo paperwork taken care of, there is no complicated exchange of communications.

Q: How can i trust Martek will be reliable? What guarantees can you give me?
A: We simply ask you to give us a try! We are confident that our expertise in serving the marine industry and our friendly nature will see us building a long term relationship.

Q: What credit payment terms can you give me?

A: Unless an existing customer, all credit payment terms will be subject to an initial credit check, however, once we are satisfied we will offer a credit limit of £4,000 on 30 days payment terms.

Q: Can you hold stocks for our vessels calling at certain ports?

A: At the moment we are able to hold stocks in UK, USA, UAE, China and Singapore. However, we will be continuously looking at ways to expand the global service. We are willing to investigate any opportunities where we may be able to serve you further at certain ports.

Q: How many sensors can I test with each canister?

A: See the manufacturer's instructions. Fixed flow regulators are usually set at 1 LPM or 0.5 LPM, therefore the gas used depends on time x volume of gas.

Q: What is the lifespan of your gases?

A: Warranty details for each gas cylinder can be seen on the datasheets.

Q: What benefits can you offer for a fleet deal?

A: Fleet deals need to be discussed and agreed on a case by case basis, but we are willing to accommodate such circumstances.

Q: How can I sign an annual agreement with Martek to supply our calgas requirements?

A: Simply ask us, we want to make your ordering experience as simple as possible.

Q: Why have you quoted a different mixture to the one I asked for? Will it still be effective?
A: We would only ever quote a different mixture if the one you have asked for is unsafe or if we don't have the mixture in our stocking range but we have an alternative that will be equally effective at calibrating your gas detection equipment.

Q: Why do some gases take longer to despatch than others?
A: Some gases have a slightly longer production process due to the requirement to have gases stabilised over a minimum amount of time: however, our gas stocks have been determined by our customers. Where we see demand for gases that might usually take longer, we will arrange to have these stocked in our hubs.

Q: Can cylinders be refilled?
A: No, our non-refillable cylinders must NEVER be refilled.

Q: Where can you get gas to the quickest?
A: UK, USA, UAE, Shanghai and Singapore.

Q: Will you offer a discount for bulk orders, loyalty rates?
A: We value loyal customers and we are continually looking at how we can reward them. Although discounts may be applied in special circumstances and on an individual customer basis - we would like to think that our good service is enough of a reason to come back.

Q: Is it certified?
A: Yes, all gases are traceable to European (EN) and American (ISO) standards.

Q: How do I know when the cylinder is full/empty?
A: The regulator has a contents gauge that gives a clear indication of the volume of gas in the cylinder.

Q: Is there a minimum order quantity?
A: No, you can order single cylinders if you require.

Q: Can i mix types?
A: Yes

Q: What flow rates can I have?
A: We can supply a large range of flow rates but generally they are typically between 0.5 and 1.5 litres per minute (LPM).

Q: How do I store Calibration Gas?
A: Dry and at room temperature of 20 deg C is best.

Q: If you miss the vessel when ordering in good time, will you organise and pay the onward carriage costs to the next port?
A: This would be dsicussed at the time as this depends upon the circumstances.
