An experienced developer and manufacturer of measuring equipment, Turnkey Instruments produces a range of solutions for environmental monitoring.

Our talented product design engineers not only produce first-class devices, but deliver exceptional technical support. This way, we can help you make the most of our equipment and ensure it always delivers valid, precise results. 

Since our measuring equipment is produced in-house, we can carry out servicing, repairs and calibration. Since each piece of instrumentation was developed and manufactured by our own engineers, nobody understands them better than us!

Our equipment provides highly accurate results for gas and air monitoring, noise and vibrations, and transportation (including on-road and off-road vehicles).

Discover some of the best measuring instruments for air pollution.

Our devices are ideal for continuously monitoring the levels of various pollutants in the air, providing real-time data on air quality.


Governments often set regulatory standards for air quality to protect public health and the environment.The primary legislation governing air quality in the UK is the Environment Act 1995, which sets out the legal framework for air quality management and establishes responsibilities for central and local government.

Under the Environment Act, the UK government has established air quality standards for various pollutants, including particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), benzene, and lead. These standards are set to protect human health and the environment.

Additionally, the UK is subject to European Union air quality directives, although the extent of their influence post-Brexit may vary depending on the agreements reached between the UK and the EU.

Our measuring equipment can ensure you meet compliance with the latest standards. 

By detecting harmful pollutants such as particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3), our monitoring equipment helps to protect people’s health by providing early warnings of potential risks.

Scientists and researchers can also air pollution monitoring data to study trends, identify sources of pollution, and assess the effectiveness of pollution control measures.

Discover our specialist testing equipement for the transportation industry.

Our accurate, practical and user friendly equipment can support vehicle safety. Our vehicle testing and compliance instruments are used in locations all around the world to ensure that vehicles are operating safely and meet the criteria set out by the appropriate agency or the legal requirements of that country.

Turnkey Instruments has collaborated with the Health and Safety Executive (HSE) and police forces in the UK to develop our testing instruments. This has led to the development of accurate and user friendly equipment which can be used to ensure compliance and improve safety standards

Our solutions include:

  • testing equipment for standard road-going vehicle MOTs (or equivalent)
  • heavy vehicle brake testers for use on off-road vehicles in mining, quarrying, rail transport or other off-road environments. 

We can also supply the brake testing equipment for any situation or use in any environment. Better yet, we also supply vehicle compliance testing instruments.

Received complaints about noise pollution? Our noise and vibration measuring equipment can help.

Our devices are used by both authorities and those who have decided to monitor noise due to complaints. They can ensure that noise levels are accurately recorded and managed, so you can safeguard your employees. 

Our noise and vibration measuring devices are using in a wide range of environments, including construction sites, quarries, iIndustrial sites, such as waste sorting sites, oil and gas plants,  road and site traffic, motorsports, airports and railways, and underground trains

They’re also used for outdoor events, such as concerts, festivals and sporting events.

The many reasons to use noise and vibration equipment.

For starters, it’s useful for quality control.  In manufacturing processes, noise and vibration measurements are critical for ensuring product quality. 

During the development phase of products, especially in industries like automotive, aerospace, and consumer electronics, noise and vibration measurements help engineers understand how their designs perform in real-world conditions. This feedback loop is crucial for optimising product performance and minimising undesirable noise or vibration levels.

Noise pollution is a significant concern, particularly in cities. 

Monitoring noise levels can help identify sources of noise pollution, after which you can develop strategies to mitigate its impact on the environment and public health.

In civil engineering, noise and vibration measurements are used to monitor the health of structures such as bridges, buildings, and dams. Changes in noise and vibration patterns can indicate structural defects or deterioration, allowing for timely maintenance and repairs to prevent catastrophic failures.

Make the most of your investment with our servicing and calibrations.

Our testing devices have been carefully developed to provide accurate readings and measurements and are approved by various bodies including MCerts, the DVSA and TUV. However, regular servicing is key to ensuring they continue to meet the approved standards.
