Product Description
The GM25-2 is an ATEX certified gas analyser, designed for a variety of applications. It is fully configurable to each client’s requirements, making it a uniquely versatile instrument.
It can be configured with infra-red channels for CH4 and CO2 analysis, with an optional LEL expansion and up to four electrochemical cells to measure any combination of O2, CO, H2S or H2. With the option of N2 balance calculation, customers can choose up to 7 gas channels.
This instrument is capable of providing three different optional pressure measurements: Atmospheric; Static (Gauge); Differential.
Optional extras to measure velocity and temperature are available.
DataField GM25 Connect
The GM25 series can be used by itself or in combination with the DataField GM25 Connect app which allows the GM25 analyser to be controlled via a mobile device or tablet. This results in faster operations whilst being able to configure how readings are taken suiting the individual users needs.

All GM25 instruments require annual service and recalibration and service.
Due to the configurable design of the GM25-2, it is suitable for almost any gas analysis application, including:
The GM25 series can be used by itself or in combination with the DataField GM25 Connect app which allows the GM25 analyser to be controlled via a mobile device or tablet.
This results in faster operations whilst being able to configure how readings are taken suiting the individual users needs. If an internet connection is present, the application can live-stream the data to the web-based portal as opposed to downloading it directly from the device after all readings have been taken, resulting in much faster access to the gas analysis data.

Product FAQs
- What is a GM25-2?
The GM25-2 is an ATEX, IECEx and UKEx rated instrument that is configurable at the point of sale. This configurability allows the GM25-2 to be used in a variety of different applications.
- How do I order my GM25-2?
Before enquiring about the GM25-2, please take a look at the instrument datasheet to view all the available expansions. The GM25-2 can include several gas and pressure measurements to suit your application. When placing your enquiry, do refer to each gas and pressure expansion required as this will factor into the final cost and lead time.
- Where can I use the GM25-2?
The GM25-2 can be configured to whichever gases you require from the list of available sensors (please refer to the datasheet for these). From there, the instrument’s ATEX rating means it can be used in Zone 1 areas. The full certification is: EEx ib IIBT1
Please review your risk assessments to ensure that the instrument has the correct certification for use in your application.
- How do I carry out monitoring with a GM25-2?
When purchased, you will receive the following with the GM25-2:
- Instrument
- Sample Pipe
- Battery Charger
- Spares Pot
- Allen Key
- USB drive with operation manual
This is referred to as the “ready-to-go site kit”. All instruments are shipped fully charged and are able to be deployed upon arrival with little to no set-up required.
The sample pipe provided is ~1m in length and includes a dust trap filter to prevent particulates from entering the sensor and causing damage. The male connector will attach to the inlet manifold of the instrument, and, on the opposite end, the silicon 1/4” tube will connect to most industry-standard sampling points. For in-depth instructions on how to operate the instrument, please view the manual file stored on the received USB drive.
- How often does my GM25-2 require servicing?
The GM25-2 requires annual service and calibration. Please contact your supplier to organise service in good time prior to the calibration date- shown on the latest calibration certificate and on the home screen of the instrument.
- How do I order spares/consumables for my GM25-2?
Identify the part you require and contact the distribution partner from whom you purchased the analyser. Alternatively, visit the Gas Data website and fill in the enquiry form associated with consumables and spares.
- How do I book a service?
It is highly recommended to book a service in advance of the instrument’s calibration date. Reach out to the distribution partner you have purchased the instrument from to receive a service slot. Servicing typically takes 10-15 working days, with collection and reshipment being included in the service cost for UK-based customers. For those sending their GM25-2 from overseas, shipping back will incur a charge.
- What is the lead time on a GM25-2?
The GM25-2 is built to order to match the gas and pressure expansion configuration determined by the customer. This, inevitably, will affect the lead time. Instrument lead times can range between 2-14 weeks – please refer to your order acknowledgement for a live lead time.
