iv UK FOCUS Tigers used in fight against arson
In the on-going fight against arson-related incidents in North-West England, Merseyside Fire & Rescue Service is using TigerLT photoionisation detectors (PIDs) from Ion Science to detect volatile organic compounds (VOCs) from ignitable liquids that have been used in the development of a fire.
Supplied by Ion Science’s UK-based distributor Shawcity, the handheld, portable TigerLT PID instruments have helped reduce costs and increase quality by preventing non-contaminated samples being sent for lab analysis.
A long-standing user of Ion Science PID instruments for more than 10 years, Merseyside Fire & Rescue Service originally used the company’s PID FirstCheck 1000+. When these became obsolete, they purchased two Tiger PIDs and have recently added two TigerLT units to their growing portfolio of Ion Science VOC monitors.
Merseyside Fire & Rescue Service’s team of four fire investigators are each issued with a personal Ion Science Tiger or TigerLT for fire investigation purposes.
Over a five-year period, Merseyside Fire & Rescue Service attended more than 1,500 incidents where fires were deliberately set using ignitable liquids. This is an average of six incidents every week.
Ian Mullen, Station Manager at Merseyside Fire & Rescue Service, Incident Investigation, comments: “Ion Science Tiger PIDs are a robust and reliable product for detecting VOCs during fire investigations.
“The instruments are a tool to assist in the detection of the presence of ignitable liquids. This also allows the Police CSI to take a sample from a ‘confirmed’ area of post-fire ignitable liquids which can be sent for lab analysis. “This prevents non-contaminated samples being processed which reduces costs and increases the quality of positive hits for ignitable liquids.
“The Tiger PIDs perform well. Our fire investigators take an instrument to each and every one of the 300 plus incidents they attend each year,” he adds. “The unit will be deployed if ignitable liquids are suspected to have been a factor in the incident.” Ion Science’s TigerLT, which offers worldwide Intrinsic Safety (IS) certification for use in potentially explosive atmospheres, is a streamlined, low cost version of Ion Science’s well proven Tiger PID model.
Like all Ion Science PID instruments, the TigerLT incorporates the company’s advanced patented fence electrode technology. This unique triple- electrode technology ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field. With a detection range of 0 - 5,000 ppm, with a 0.1 ppm minimum sensitivity, Ion Science’s TigerLT also offers an unrivalled industry response time of just two seconds and equally quick clear down. Both simple to operate and service, the TigerLT offers easy access to the lamp and sensor. The intrinsically safe instrument also meets ATEX, IECEx, UL and CSA standards.
It features long life rechargeable Li-ion batteries that can be safely replaced in hazardous environments and give up to 24 hours usage. Fast battery charging allows the instrument to be fully charged in 6.5 hours, while eight hours of use can be achieved from 1.5 hours of charging time.
TigerLT features a protective, removable boot for harsh environments, while a large, clear back-lit display allows for easy viewing in any light condition. It is IP65 rated against water ingress. An integrated torch helps direct the instrument’s probe into dimly lit areas. Other features include a loud 95 dB audible alarm, multiple language support and is IP65 rated against water ingress.
Ian comments: “The service from Ion Science and its distributor Shawcity has always been very good. We can’t fault the Tiger PIDs which offer a number of practical features for fire investigation, a short power up time, rubber boot, bright colour for ease of visibility and robust design.” For More Info, email:

Advanced high-speed infrared camera offers even more performance when recording thermal images of extremely fast thermal processes For some years now, the ImageIR®
Its sensitive elements are larger than those of conventional detectors and are arranged at a distance of 30 µm. As a result, the model has an enormous thermal sensitivity of 0.015 K. This excellent signal-to- noise ratio is accompanied by integration times of less than 10 µs for technically relevant object temperatures. Thereby frame rates of up to 105 kHz can be realized. For this reason, the infrared camera is predestined for the solution of measurement and testing tasks, in which extremely rapid thermal processes are to be captured and recorded.

An example of this is the analysis of combustion processes. Others can be found in various areas of research. Questions concerning aerodynamics and flow technology in the field of aerospace and applications, in which laser technology is used, are linked to such high frame rates.
High temporal resolution also plays a role in the analysis of wearing processes within the automotive industry. In this area, the ImageIR® 5300 also demonstrates the strengths of its concept. The automated
Total cloud based monitoring solutions
Thermal Rotate Check (TRC) IR rotation test system from InfraTec provides the framework for this. As part of this, the infrared camera supports the precise analysis of fast rotating components such as tyres and brakes. The results of such analyses provide important information about how well the test objects withstand continuous operation, which signs of wear are present and how serious they are, and which mechanisms cause them.
The improved frame rate of the ImageIR® 5300 ensures that users can use this model to solve a wide range of tasks in
industry and science. Their modular design consisting of an optics, detector and interface module makes it easy to adapt to a wide variety of measurement scenarios. The integrated process and trigger interface enables the infrared camera to be synchronized precisely with external processes for analyses – and in the case of the ImageIR®
be connected at maximum speeds. For More Info, email:

One of Pulsar Instruments’ most popular noise warning products, the Pulsar SafeEar, has now been made weatherproof. This new IP65 rated weatherproof noise activated warning sign lights up to warn site workers and visitors when noise levels have exceeded a pre-set decibel trigger. The sign will indicate that hearing protection must be worn, and when the light goes off workers know it is safe to remove their hearing PPE.
email: For More Info, email: email:
The SafeEar is ideal for industrial processes, construction sites, outdoor maintenance areas, exteriors of business premises and environments where water or high levels of moisture and dust may be present.
These signs don’t have to be only used outside. As the signs are IP65 rated they can be used in any area where moisture might be present or in areas that undergo high levels of industrial cleaning. They can also be used outside business premises to help people keep their noise levels down to reduce the risks of noise complaints.
