  1. Fever Screening: Thermal Imaging and Non-Contact Instruments

    Fever Screening: Thermal Imaging and Non-Contact Instruments

    On the 11th March 2020, The World Health Organisation (WHO), responsible for assessing the global developments of COVID-19, characterised the outbreak as a pandemic¹. As of 31st March 2020, it is reported that the pandemic has affected more than 179 countries, with more than 823,000 cases confirmed worldwide².

    HFO-1234YF in Automotive Air Conditioning

    From 2017, a change in the law required the introduction of a new refrigerant – HFO-1234YF (also known as R-1234YF) – in air-conditioning systems of vehicles, replacing the widely used R134a. This has implications for automotive engineers and HVAC technicians, particularly when it comes to using appropriate gas leak detectors.

    Smart Meters: What is the State of the UK Rollout?

    Smart Meters: UK Rollout

    Energy suppliers are obliged by Ofgem to take all reasonable steps possible to have a smart meter installed in the premises of all their domestic and small business customers by the end of 20201. The benefits of smart meters from both a consumer and environmental point of view have been loudly trumpeted in press releases and advertisements, but significant doubts remain and the 2020 deadline looks more and more optimistic when set against the facts. So where is the UK’s smart meter project?

  5. PoE: What is Power over Ethernet?

    PoE: What is Power over Ethernet?

    Power over Ethernet

    Power over Ethernet, or PoE for short, is a feature that allows electrical power to be carried by network cables over an existing data connection. This means that network cables can pass electricity through them. For this to happen, a Cat5e or Cat6 ethernet cable is needed. The job of this cable is to connect two devices together for the local network, as well as for internet network and file sharing. The company Cisco is credited with pioneering the PoE movement, when in 2000 they came up with the first ever successful system. There are many reasons for PoE’s rise to prominence, with the expansion of technology obviously a major factor.

  6. Using Thermal Imaging with the Blower Door Method for Airtightness

    Using Thermal Imaging with the Blower Door Method for Airtightness

    Thermal-Imaging-Blower-Door-header

    Assessing air permeability is the best way of checking whether a property is airtight or not, particularly around areas other than windows and door frames. Airtightness is an important factor to consider as it gives a clear indication of material, component and workmanship standards as well as having an effect on running costs. Thermal imaging provides a great way of assessing air permeability using the blower door method and is therefore ideal for spotting defects before they start to worsen or cost money.

  7. Using Thermal Imaging for Mould Detection

    Using Thermal Imaging for Mould Detection

    Thermal-Imaging-Mould-Detection-Banner

    Mould is a widespread problem affecting old and new buildings alike, particularly when new windows or doorframes are fitted retrospectively. Thermal imaging can be used in conjunction with humidity and air temperature measurement to detect mould-friendly conditions before a serious problem develops, thereby protecting the health of occupants and workers as well as lowering costs of remedial work.

    Using Thermal Imaging to Inspect Solar Panel Installations

    Solar-Panels-Thermal-Cameras-Banner

    Solar panel installations are becoming increasingly popular from both a private, commercial and governmental perspective amid a fall in installation costs and a long-term price rise in non-renewable energy sources such as coal, oil and gas. However, solar panels require regular maintenance, which is where thermal imaging can provide an efficient solution to many of the challenges posed.

    Understanding Surge Protection Devices (SPDs)

    Surge-Protection-Banner

    The introduction of the 18th Edition Wiring Regulations saw a change in the requirements surrounding overvoltage protection a.k.a. surge protection that will result in a much higher prevalence across a range of different properties. Here, we aim to have a look at the consequences of electricity surges, related regulatory requirements, the different types of surge protection device (SPD) available, and where and when to install them.

    What does the Energy-related Product Directive mean for NOx in Boilers?

    ErP-Nitrogen-Oxide-Banner

    The Energy-related Product Directive (ErP) is a wide ranging piece of EU legislation that aims to reduce emissions in Europe through improving the labelling and efficiency of a wide range of appliances from lighting to refrigerators. It has now been in force for a number of years having first been passed in 2009 but various provisions have come into force at later dates. These include Regulation 813/2013 that sets out requirements for the eco design of space heaters and combination heaters.
