Service & Calibration

We recommend returning your gas detection instrument annually for service and calibration. Our qualified engineers are on hand to provide you with the repair, maintenance and calibration of your instrument, with fast turnaround.

Return an instrument for Service or Calibration

Annual service and calibration of your gas detector

It is important that your gas detection instruments are re-calibrated on an annual basis to ensure they continue to provide you with accurate, reliable results and that they maintain their extended warranty. Our Engineers will examine your instrument thoroughly to ensure it is calibrated to the same standard as when it left the factory.

Fast turnaround of your gas detection instrument

Our skilled technicians are trained to the highest standards and will ensure your gas detector is back up and running to optimal working order, and returned to you as quickly as possible.

Our Engineers are qualified to provide

Factory re-calibration
Repairs (warranty and non-warranty)
Extended warranty
Full reprogramming capabilities
Stock holding of spare parts
Advanced technical knowledge

Returning a gas detection instrument to us

In addition to servicing gas detection instruments here at ION Science, we have a network of Authorised Service Centres located around the globe trained and qualified to the highest standards. We ensure all of our Service Centres maintain our original manufacturers quality when carrying out full warranty and Intrinsic Safety procedures.

For service and calibration of your gas detector, your instrument can be returned to a local ION Science Authorised Service Centre in your area. If a local Service Centre isn’t located near you, your instrument can be returned to the ION Science Head Office.

Return your instrument for Service & Calibration

Your instruments can be returned for Service and Calibration to an ION Science Authorised Service Centre, or to the UK Head Office here.

Diffusion Vs. Pumped Fixed Gas Detection

Diffusion Fixed Gas Detection Device

A diffusion gas detection device works, as the name suggests, on the diffusion principle. The sensor is exposed to the ambient air and will measure the gas by means of the diffusion principle. Diffusion means proportional spread of molecules over the available space (from high concentration to low concentration). This also means that a diffusion gas detection device is only able to measure the concentration of gases at the location where the device is located. Since there is no forced flow of the gas to be measured, this device is not suitable for taking measurements remotely, but they do accurately identify what’s present in a given location.

Pumped Fixed Gas Detection Device

Pumped instruments are equipped with a built-in sampling pump. This means that the device is constantly drawing in gases. A sampling hose may be connected to extend the reach. This means that you can take a measurement from a safe distance so you have an idea of which gases will be present in which concentration before you are exposed to this environment. This allows you to make an appropriate risk analysis and make the right strategy and PPE choices based on the measurement results. By positioning the measuring hose correctly, you can also make a correct measurement at different heights to chart all risks.
