Guernsey’s States Works is using an Ion Science (www.ionscience.com) TigerLT handheld photoionisation detector (PID) to measure volatile organic compounds (VOCs) being emitted from an odour control system installed at Guernsey’s waste transfer station. Supplied by distributor Shawcity and chosen for its portability, high detection rates and range of response factors, the instrument is helping to prevent the escape of malodours into the surrounding environment.
States Works is using the Ion Science TigerLT PID instrument at three outlet ports on each of the transfer station’s odour control carbon filter vessels where it is monitoring VOCs being emitted at quarter, half and three quarters depths of the carbon filter media. It enables States Works to estimate usage of the media so they can be replaced to ensure malodours are not being released into the environment.
Yannic Bearder, Senior Environmental Monitoring Technician at States Works, comments: “Part of our role is to ensure that the new waste transfer station and old landfill sites are not affecting the environment or impacting the local community.
“The company that installed the odour control system at the waste transfer station recommended we use Ion Science’s Tiger PID to measure VOCs from the three outlet ports to help assess utilisation of the carbon filter media.”
The TigerLT instrument is being used by States Works for weekly monitoring of VOCs with the data downloaded manually via USB and logged onto a spreadsheet.
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 market-leading PID technology with advanced patented fence electrode system. This three-electrode format ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field.
With a detection range of 0.1 - 5,000 ppm utilising a standard two-point calibration protocol, Ion Science’s robust 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 with batteries that can be safely replaced in hazardous environments. The intrinsically safe instrument also meets ATEX, IECEx, UL and CSA standards.
Yannic continues: “Ion Science’s distributor Shawcity recommended the Ion Science TigerLT VOC monitor as it met our requirement for portability, high detection rates and range of response factors. Although the instrument is only being used outdoors for short periods of time, it also has a reassuringly rugged design.”
The TigerLT six pin MiniPID detector cell with anti-contamination design dramatically extends run time in the field. Low cost filters and lamps can be easily changed in minutes, minimising downtime.
It features long life rechargeable Li-ion batteries which 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 IP 65 rated against water ingress. An integrated torch is designed for directing the instrument’s probe into dimly lit areas. Other features include a loud 95 dB audible alarm and multiple language support.
Ready to use, straight out of the box, the TigerLT does not require complicated set up procedures via a PC to perform basic functions.
