Gas Detection - UK Focus xv
New Volatile Organic Compound Detector Stands Out in the Field
When a new hand held photoionisation detection (PID) instrument was required by supplier of environmental sampling and monitoring equipment, Van Walt, the revolutionary Tiger volatile organic compound (VOC) detector from Ion Science – leading manufacturer of PID/VOC detectors – was considered the best solution on the market.
Supplied by Shawcity, UK distributor of Ion Science products, the Tiger VOC detectors are being used by Van Walt’s customers, who are mostly environmental research consultants, in the UK, Spain and New Zealand.
Vincent Van Walt, Director at Van Walt explains: “Our reputation for supplying high quality equipment, which has been built up over 30 years, is of paramount importance to us. That’s why we meticulously source products that are the latest, most effi cient and most reliable available. The Tiger, which is also backed by a fi rst class service, support and training package from Shawcity, meets all these requirements and more.”
He continues: “Our customers expect the right tools for the job and the Tiger’s PID capabilities are second to none. It utilises advanced patented fence electrode technology with increased resistance to humidity and contamination, meaning it is less prone to fogging. Together with a clear, easy to read display, this makes the Tiger ideal for use in harsh fi eld environments. Equipment is often designed by people who have never set foot in the fi eld and this is clearly not the case with the Tiger. The PID sits comfortably in the hand for easy VOC detection, offers fast start-up with no complicated set-up processes and is entirely fi t for purpose.”
A robust hand held VOC detector, Tiger provides a dynamic detection range of 1ppb to 20,000ppm, offering the widest measurement range of any other VOC instrument on the market. Ready to use, straight out of the box, the Tiger requires no complex set up procedures via a PC to perform basic functions and provides the best available VOC detection and software features available.
Ion Science’s Tiger also has the fastest response time on the market of just two seconds and can be connected directly to a PC via the USB offering fast data download capabilities. It has been designed for the safe replacement of batteries in hazardous environments and is intrinsically safe - meeting ATEX, IECEx, UL and CSA standards. Van Walt offers its environmental research equipment on a sale or rental basis but most customers choose to hire the Tigers as they need to be calibrated to suit individual applications.

Wireless Gas Detection with the BM25 Area Monitor
BM25 Wireless is a tough looking transportable multi-gas area monitor designed for worker protection to ensure safe levels of gas before workers enter hazardous areas, monitoring continuously during welding and other maintenance work , and mobile or short term work in areas where fi xed detection systems are not suitable. Applications include shutdown sites, rig overhauls and fence-line surveillance.
The Wireless BM25 utilises a mesh style network ensuring increased reliability in safety-critical situations. In a mesh network all units are connected peer to peer without central hierarchy, thereby forming a net-like structure. Consequently, each unit can receive, send and relay data.
One of the main benefi ts of the mesh style network over ‘daisy-chain’ non-wireless systems is that should one monitor fail, its neighbours go through another route. Once the fault has been corrected, the communication resumes automatically. The two groups merge together to form only one group again.
Up to 30 BM 25s can be ‘meshed’ on the same network of up to 1Km apart and up to 16 networks can coexist with no interference. Adding a BM 25 on an existing network has never been so easy as you just need to turn it on. The BM25 is automatically added on the network.
The Wireless BM25 is capable of monitoring from one to fi ve gases through diffusion or sample draw. There are now 32 interchangeable “smart” sensor options available for the BM25 including PID, IR, electrochemical and catalytic sensors. Interchangeable/fi eld replaceable sensors provide the fl exibility of monitoring in a variety of applications thus reducing operating costs and downtime associated with instrument/sensor service.
When the BM25 detects a hazardous level of oxygen, toxic or combustible gas, the top-mounted beacon sends a fl ashing, bright signal in all directions while emitting a powerful, 103 dB siren alarm. If a BM25 goes into gas alarm, all BM25s in the network will report a corresponding alarm. Similarly, if one BM 25 fails a communication request then all the BM25’s in the chain will alert you of a fault, letting you get straight to the source of the problem. In all cases, the local gas detection capability remains effective and each BM25 will provide local alarm capability in the presence of gas.
The concave face design and construction ensures that gas sensors are protected and not blocked from the atmosphere in the event that the BM25 is knocked on its face or side in chaotic work environments. The IP66 ingress protection rating allows units to be used in harsh outdoor environments without damage from dust and water.
The operating runtime varies between 35 hours and 130 hours (depending on confi guration) and takes only 4 and a 1/2 hours to recharge. A safe trickle charger is also available for long-term area monitoring in classifi ed zones.
