xiv UK Focus - Health & Safety FTIR Gas Analyser Reveals Toxicity of Ancient Siege Technique A revolutionary gas analyser from leading environmental instrumentation company Quantitech (UK) has played a starring role in a major History Channel series.
The Milton Keynes based company was contacted by Wild Dream Films, who were looking for instrumentation to measure toxic gases in air to feature in an episode of a series called Ancient Discoveries. Following consultation with Quantitech’s Dr Andrew Hobson, the production company used a Gasmet DX- 4030 gas analyser to measure the toxic gases emitted from smouldering materials, in an episode which recreated the Roman siege of Ambracia in 189BC.
The DX-4030 is a new analyser based on tried and tested Gasmet technology providing both field-usability and high levels of analytical performance. The DX-4030 employs FTIR (Fourier Transform InfraRed Spectroscopy) analysis producing almost instantaneous readings for multiple compounds across a wide measurement range that extends to sub-ppm levels.
According to Wild Dream Films: “In Roman times there was a siege technique called sapping, which involved excavating tunnels under fortresses and castles and then surprising the enemy. A method to prevent this was blowing toxic smoke from smouldering chicken feathers into the tunnels. The DX-4030 from Quantitech allowed us to measure the toxic gases this produced.
“By using the DX-4030 we found that the level of toxic gases was extremely high and potentially poisonous. The analyser was very easy to use and enabled us to shed new light on these siege prevention techniques.” The DX-4030 is more commonly used for the analysis of workplace and process gases in applications as diverse as contaminated land, chemical spill response and industrial hygiene.

The new EVM from Shawcity (UK) is a rugged and easy to use environmental monitor which combines several instruments in one. With the capability to simultaneously measure and datalog particulates, Volatile Organic Compounds (VOCs), toxic gas, carbon dioxide, relative humidity, temperature and air velocity the EVM-7 provides a cost effective solution and reduces the need for multiple instruments. This versatility enables it to be used in the industrial, commercial and education sectors.
A unique dial-in impactor allows easy selection of particulate settings. A built-in sampling pump assists in the collection of dust and a photometer provides real-time measurement. A standard 37 mm filter cassette offers gravimetric sampling and laboratory analysis.
Using a high-performance PhotoIonisation Detector (PID) EVM-7 measures volatile organic compounds (VOCs). Combined with the ability to also simultaneously measure carbon dioxide and another toxic gas, it helps to identify air quality issues. Additionally, EVM-7 uses smart sensor technology, which offers automatic sensor recognition at power-on, calibration levels, service dates, temperature compensation and other sensor specific data.
Sampling sessions and studies stored in the internal memory can later be downloaded into datalogging software for analysis, charting and graphing. Reader Reply Card no 261
New Versatile Noise Activated Warning Sign Launched
Cirrus Research (UK) has unveiled its new electronic noise activated warning sign – the Sound Sign.
The Sound Sign is a highly visible noise activated
warning sign that has been designed for use in environments where there is a need to warn or indicate when a designated noise level is exceeded.
Easy to install and operate, it is controlled by setting a noise trigger level, and connecting the 12v power supply to the unit. When noise reaches the set level, the Sound Sign illuminates and the warning information can be clearly seen.
Suitable for the management and control of noise levels in many different applications, Sound Sign is perfect for use in industrial workplaces.
James Tingay, Group Marketing Manager for Cirrus Research said:“In the workplace, noise surveys may have indicated that at times, recommended noise levels are exceeded, but that the wearing of constant hearing protection is not required. By using the Sound Sign, employees can be quickly and easily informed when PPE (Personal Protective Equipment) is required and when it can be removed. Sound Sign remains inactive and blank when sound levels are at an acceptable level, removing any confusion that can occur with traditional warning signs.
Apart from Health & Safety applications, the Sound Sign can also be used in offices, libraries, hospitals and schools, with custom versions available with messages designed to inform about designated quiet areas.”
If there is a need ensure that the warning can be seen over a large area, up to three Remote Display Units can be quickly and simply connected to the Master Unit, mirroring the action and information of the controlling Sound Sign. It can also be easily upgraded with a Data Logger which can record noise levels over long periods of time, allowing the user to detect patterns of noise.
