Southern Water buys 800th gas detector!

Southern Water (UK) has recently purchased its 800th Tetra portable gas detector from Crowcon, mainly for use by staff working in confined spaces with sewerage processes.

Southern Water (UK) has recently purchased its 800th Tetra portable gas detector from Crowcon. This represents a major investment and is a testament to the reliability and durability of the device. ‘We chose the Tetra because it is simple to use, easy to maintain and extremely durable,’ said the Southern Water senior health and safety advisor Andy Nicholls.

‘They are life-preserving bits of equipment and you simply can’t compare the cost of a life against the cost of a detector.

Saying that, the units were very good value for money’.

The detectors are used primarily by staff working in confined spaces in the wastewater, sewerage, clean water and process water sectors and for procedures such as chlorine change-over.

They are also used by support staff such as scientists, technicians and health and safety advisors, and for staff training.

‘We are now in the era of the ‘intelligent worker’, who wants to understand better what is going on around them,’ continued Andy.

‘Our staff are fully conversant with health and safety legislation and expect to have the right equipment at all times.

The Tetra is therefore integral to our business - I can’t think of anything that is wrong with it’.

Designed for the most demanding conditions, the Tetra can monitor up to four gases at once, including oxygen, flammable gas and a full range of toxic gases.

It has a single button that controls all functions - even with a gloved hand - and a bright display gives simultaneous viewing of all gas readings, alarm conditions and battery life.

The unit is water and dust-resistant to IP65, floats in water and is ATEX approved for use in hazardous areas.

If a gas hazard is detected, the Tetra gives an instant warning with a powerful 94 dBA alarm, an extremely bright red and blue alternate flashing lights and by vibrating.

‘Our staff really like the red/blue light,’ commented Andy.

‘There are so many flashing red lights all around these days that the red/blue one instantly stands out.

The alarm is also impossible to miss, even in the very noisy environments our staff often work in’.

Six user-configurable 8-amp relays with selectable zoning and voting are included.

The MC600 features six back-lit LCD display modules that each have two lines, with eight characters available per line.

Large multi-coloured LED Ready, Alarm, Warning and Fault indicators (that are easy to read in daylight) supplement the LCD digital displays, and keypad controls are provided for setup, calibration and gas reading functions, and self-test.

The MC600 six auxiliary 8-Amp relays are user-configurable to activate external devices such as horns or beacons on any of the six channels, whether for alarm or warning setpoints.

Wolf wins grampian Fire contract

After completion of a robust assessment process, Wolf Safety has won a major contract to supply 400 of its new LED rechargeable right angled R-50 safety torches to Grampian Fire and Rescue Service.

After completion of a robust assessment process, competing with four other companies, Wolf Safety has won a major contract to supply 400 of its new LED rechargeable right angled R-50 safety torches to Grampian Fire and Rescue Service. Exhaustive testing was undertaken to simulate the extreme environmental conditions to which the torches could be exposed - heat, smoke, condensation and water. The evaluation panel concluded that the Wolf R50 was the best LED type rechargeable safety torch currently available for safe use by firefighters on operational duties.

Chief Fire Officer David Dalziel of Grampian Fire and Rescue Service welcomed the introduction of this modern and highly effective item of operational equipment for front line use.

‘Crew safety and the innovative use of technology are areas we sought from the outset.

Toxic and flammable gases easily monitored

Toxic or flammable gases such as carbon monoxide, carbon dioxide and methane can be easily monitored from multiple locations with the new Crowcon PGSi Programmable Monitoring System.

Toxic or flammable gases such as carbon monoxide, carbon dioxide and methane can be easily monitored from multiple locations with the new Crowcon PGSi Programmable Monitoring System. Monitoring up to four different gases at once, from up to 32 individual sampling points, the PGSi is ideal for applications such as carbon monoxide monitoring in car parks and tunnels, carbon dioxide monitoring in breweries and distilleries, or monitoring methane leaks from the heating systems of buildings. By doing away with the need for multiple fixed detectors, the sampling system significantly reduces installation and maintenance costs.

Each sample line can be up to 1km in length and sample times for each monitoring point are individually adjustable and can be sequenced in any order.

A dual pump arrangement ensures that samples reach the gas sensors as quickly as possible.

Filters, flow-fail devices, internal gas leak detectors and flame arrestors are all fitted as standard to ensure safe and reliable operation at all times.

The system is controlled by a PC using Windows XP-based software.

A screen displays individual sample locations, gas levels and alarms.

It operates up to 32 relays (which activate alarm devices or send a signal to external control equipment) and provides comprehensive data-logging facilities, with gas data displayed either in tabular or graphical formats.

The PC can be monitored remotely via an optional modem, allowing status checks and the uploading of datalog files.

How sure are you about CO levels in your plant?

If you have a Carbon Monoxide concern and need to know more, the Lascar Electronics EL-USB-CO carbon monoxide data logger can help in determining the nature of the problem.

If you have a carbon monoxide concern and need to know more, the Lascar Electronics EL-USB-CO carbon monoxide data logger can help in determining the nature of the problem. Carbon Monoxide (CO) is a poisonous gas, which is both odourless and colourless. It is produced by equipment/machinery that isn’t working correctly and often (as in the case of motor vehicles) also when it is.

The Lascar EL-USB-CO data logger monitors and records CO levels in an environment over a period of time.

This can help the user to determine where and when peak levels of CO occur, allowing corrective action to be carried out to remedy the problem.

Application areas include: construction sites, furnace rooms, ventilation systems, office blocks, homes near motor traffic (especially in enclosed areas such as tunnels and garaging).

The EL-USB-CO stores over 32,000 readings and can record CO levels from 0 to 1000 ppm.

Set-up of the data logger is completed using the supplied EL-USB software, with the EL-USB-CO plugging directly into the USB port of a PC.

Here the user can assign the logger a name, choose a sample rate (from a choice of once every: 10 secs, 30 secs, 1 mins, 5 mins), as well as determining a high-alarm level.

Once setup is complete the EL-USB-CO should be left in the environment where the study is to take place.

When ready, the data can downloaded onto the PC, graphed, printed and exported to other applications.

Technology: At the heart of the system is a state-of-the-art electrochemical CO sensor.

It has been chosen for its high-sensitivity, high accuracy, resistance to other gases and long-term stability.

Low-power processor technology allows the logger to run up to one year on its internal battery.

The logger is RoHS compliant.

Design History: The EL-USB-CO is the latest in the extremely successful line of the Lascar EL-USB data loggers, which have found numerous applications all over the world.

The entire design process is done in-house, using the Lascar team of graphic designers and electronic, mechanical and software engineers.

For this reason, customisation, from badged software or loggers to full bespoke design, can be carried out to ISO 9001 standard.

Lascar now offer a custom design and manufacture service, bringing together the best of Western design methods and Far-Eastern manufacture to provide our customers with a truly world class service.

The EL-USB-CO is available for purchase at GBP49 from the Lascar website.
