exhaust gas analyser & mot smoke meter
GEMCO supplies professional emissions testing equipment designed for DVSA-approved MOT stations, workshops and Automated Test Lane (ATL) environments. Our range includes combined exhaust gas analysers and standalone diesel smoke meters used to test petrol and diesel vehicle emissions during MOT inspections.
These systems provide accurate measurement of exhaust gases and diesel smoke opacity, helping workshops ensure vehicles meet current UK environmental regulations. Designed for reliability and ease of use in busy workshop environments, GEMCO emissions testers deliver fast, accurate results while supporting compliance with DVSA testing requirements.
All emissions testing equipment supplied by GEMCO is installed, calibrated and supported by our nationwide engineering network, ensuring dependable operation and long-term performance.
OUR RANGE OF emissions testing equipment
combined gas & smoke emission analysers
Combined exhaust gas analysers allow workshops to carry out both petrol exhaust gas testing and diesel smoke opacity testing using a single integrated system.
Systems such as the Tecalemit TGD/MDS Combined Gas and Smoke Emission Analyser and the Bradbury BRADCOMBI4 Combined Emissions Analyser provide complete MOT emissions testing capability within one platform.
Key features include:
Combined gas analysis and diesel smoke measurement
DVSA-approved emissions testing equipment
Integrated Windows-based PC control systems
Large colour displays for clear viewing of results
Low warm-up times for faster testing
Robust mobile cabinets designed for workshop environments
These systems are ideal for MOT stations and workshops requiring full emissions testing capability for both petrol and diesel vehicles.
standalone diesel smoke meters
Diesel smoke meters provide dedicated testing for diesel engine emissions during MOT inspections. These systems measure smoke opacity produced by diesel engines to confirm compliance with MOT environmental standards.
Bradbury standalone smoke meters are designed for reliability and flexibility across a wide range of vehicles including cars, vans, trucks, buses and plant machinery.
Key features include:
DVSA-approved diesel smoke testing systems
Battery RPM measurement and oil temperature probes
23″ colour monitors for clear test results
Keyboard and mouse with protective covers
Integrated A4 printers for emissions test reports
Durable mobile cabinets for workshop environments
Standalone smoke meters are available with both Bluetooth and cabled smoke head options to suit different workshop setups.
DVSA Approved emissions testing equipment
All emissions testing systems supplied by GEMCO are designed to meet DVSA requirements for MOT emissions testing.
Advanced emissions testing software supports modern vehicle standards including Euro 6 diesel engines, while optional vehicle communication interfaces can provide engine temperature and RPM information directly from EOBD-equipped vehicles.
Selecting high-quality emissions testing equipment ensures workshops maintain accurate testing standards while remaining compliant with current MOT regulations.

Frequently Asked Questions about emissions testing equipment
-
An exhaust gas analyser measures gases produced by petrol engines, including carbon monoxide, carbon dioxide and hydrocarbons, to ensure vehicles meet emissions regulations during MOT testing.
-
A diesel smoke meter measures the opacity of smoke produced by diesel engines during emissions testing to ensure vehicles meet MOT environmental standards.
-
Yes. Emissions testing equipment used for MOT inspections must be approved by the DVSA to ensure accurate and compliant emissions measurements.
-
Combined emissions analysers can test both petrol and diesel vehicles, while standalone smoke meters are used specifically for diesel emissions testing.
The Tecalemit MDS is a modular Combined Emission Tester which as standard, incorporates a blue tooth smoke head and a PC using a windows operating system, all housed in a stylish cabinet. The gasbench has no warmup time, meaning you can start work immediately. The TGD/MDS is a truly modular system and can be expanded to include vehicle diagnostic units Discope 802 and DiOBD. The smoke meter is Bluetooth Class 1 approved with a range of up to 100 metres. It is mains powered, 240v AC, with a 24v DC transformer protected to IP65. Being mains powered, the smoke meter is continuously maintained at operating temperature and does not require re-charge or replacement of expensive batteries, which over the long term can prove an expensive maintenance cost. Current UK specification requires the emission tester to have OIML Class I approval, however, the TGD/MDS Emission Tester is approved to Class 00, two classes higher than required under current DVSA legislation. With vehicle emissions reducing following the introduction of new technologies, should DVSA decide to make changes to the OIML class specification for gas analysers, the TGD/MDS is ready for them. The new design of condensate trap detects moisture using an electrical sensor; this leads to improved accuracy, a reduction in condensate problems and a reduction in pump running times.
The TGD/MDS is upgradable to measure NOx at an additional cost. The TGD/MDS is also a natural addition to the Tecalemit ATL (Automated Test Lane) as the computer can also serve the brake tester in the ATL lane. This streamlines the equipment in your workshop.
