Gas sensors

Innovative air quality solutions

If you're looking for gas detection sensors, our specialist range of robust, reliable gas sensors will provide you with the technology for fast, reliable and consistent detection, ideal for applications where superior performance, accuracy and stability are paramount across indoor, outdoor and harsh environments.

We partner with leading innovative manufacturers of world-class, gas sensing and air-quality monitoring solutions, principally non-dispersive infrared (NDIR) CO2 sensors, laser particle dust sensors, VOC, formaldehyde and indoor and outdoor air-quality sensor modules. This sensor range covers regulated pollutants such as nitrogen oxide/dioxide, fine particulate matter and ozone, alongside key parameters such as temperature and humidity. From state-of-the-art research, development and production facilities, they are ISO9001 and IATF16949 (automotive) accredited.

Custom solutions for new capabilities

An important addition to our sensors' capability, we offer fully customisable sensors to help solve more complex challenges. We can help you design and build a complete solution to your needs with customer-specific combinations tailored to your specific applications need.

Our in-house technical engineering experts will support you throughout your project. We have years of experience solving unique challenges, complex designs and supporting innovative solutions across many types of applications. Whether you need help with a sensor selection, custom options or advice about design, we’re well placed to support you.

    To enable fast, wireless deployment of data-critical industrial and commercial sensor solutions, that are cost-effective with the aim to drive better indoor and outdoor air -quality standards, you can create custom display housing/enclosures and develop specific combinations of:

    • Wireless connectivity – Bluetooth, Wi-Fi, LoRa and RF 
    • Sensors – CO2, VOC, RH & Temperature, Air Quality, Dust and particle 
    • Along with many display, controller, housing/ enclosure, interface or wireless connectivity options

    Our technologies

    Discover our range of technologies

    Environmental and air quality sensors

    CO2 sensors

    These CO2 modules are for both indoor and outdoor applications and ideal for measuring CO2 concentration levels up to 5000 ppm featuring:

    • Single beam Non-Dispersive Infrared (NDIR) technology
    • Small, compact and easy to install
    • High accuracy and stability
    • Long life span
    • Signal output PWM/UART/I²C
    • Auto-calibration – no need for maintenance

    Volatile organic compound (VOC) sensors


    Used to detect and monitor humidity, temperature and volatile organic compounds (VOCs) and provide the necessary data to alert connected systems to clean the air accordingly.

    Typical sensor products are required to be sensitive, robust and small in size, they can be easily installed within filtration, pollen filters and HVAC systems. These are Electrode electrochemical sensors, which use the diffusion principle to measure gas concentration in the air.

    With built-in digital temperature and humidity sensor combined with intelligent algorithms, the concentration measurement is more accurate.

    Main features:

    • Also responds to alcohol, benzene and naphthalene
    • High sensitivity, good stability
    • Low power consumption
    • Temperature compensation algorithm, good linearity
    • Fast response <5s
    • Long life span

    Perfect for applications such as air purifiers, indoor air quality monitors and HVAC/ fresh air system control.

    Oxygen sensors

    Oxygen sensors

    These are a type of ultrasonic sensor measuring accurate and stable concentration and flow of oxygen gas. These are durable options perfect for medical applications such as ventilators, respiratory devices and vaporizers giving high performance, accuracy and fast response with little to no drift and no need for routine calibration.

    • Long life span
    • Small, compact size
    • Flexible installation

    Combination sensors

    With the environmental sensor market likely to grow exponentially over the next few years, a huge opportunity to generate smarter sensor solutions across both indoor and outdoor environments is opening up, along with a shift in preference from single parameter sensors to combined ones – those measuring more than one parameter in a single device where small size and low power consumption are a key requirement.

    These fully customisable solutions allow multiple sensors to be integrated to measure several parameters at once, as well as have wireless capabilities for remote monitoring and controlling and provide an advantage when size or space is a restriction within your design.

    Our sensor experts are best placed with many years’ experience with multi-sensor modules and assisting with complete solutions including both hardware and software and complex, challenging designs.
