A record 'Fab Four' combination of new instruments

Casella CEL, the specialist provider of workplace monitoring technologies, launches four new ATEX approved, intrinsically safe (I.S.), portable instruments: the VOC Pro Air Monitor, Apex Personal Sampling Pump, the CEL-300 Noise Dosimeter and the Microdust 880 hand held dust monitor, for monitoring all aspects of occupational and environmental parameters across most industry sectors.

VOC Pro Air Monitor
VOC Pro is a new ATEX & UL certified, hand held, photoionisation monitor that can quickly and accurately detect levels of total VOC's (Volatile Organic Compounds) in potentially explosive atmospheres. The unit will help Occupational Hygienists, Safety and Environmental Managers to monitor levels of VOC's in both indoor and outdoor applications, recording the levels, to check compliance with both COSHH legislation and the Solvents Emission Directive (SED).

With a large, easy to read LCD display, this new hand held meter is simple to use and provides rapid, accurate detection of a wide range of organic compounds. The onboard data logging facility and dedicated download software allow data to be stored for auditing and record keeping purposes.

Apex Personal Sampling Pump
In response to overwhelming customer demand, the new I.S. version of Casella's market leading Apex Personal Sampling Pump range allows employers to undertake personal and area sampling for dusts, fumes, gases, vapours and VOC's (Volatile Organic Compounds) in potentially explosive atmospheres.

This easy to use, versatile and robust range is fully compliant with both UL and ATEX standards - the first UK manufactured personal air sampling pumps to be granted these approvals.

CEL-300 Noise Dosimeter
A new I.S. version of Casella's market leading CEL-320 and CEL-360 series noise dosimeters, allows individuals to carry out personal noise dosimet e ry in potentially explosive atmospheres. Rugged and simple to use, this instrument is compliant with ATEX standards, making it the first UK manufactured noise dosimeter to be granted this approval.

The CEL-300 series of dosimeters has been designed to be intuitive, with all the necessary international noise dose standards built in, so no setup is required. Data from the instruments is easy to download, giving standard noise dose reports and time history data, allowing noise exposure to be pinpointed to specific activities during the day. The CEL-300 series instruments can also be converted into a sound level meter by simply changing the microphone, allowing the unit to be used for general noise surveys within the same hazardous environments. The dosimeters exceed International Standards for acoustic and electro-acoustic test methods and performance requirements.

Microdust 880 Dust Monitor
The Microdust 880 is a hand held real time dust monitor capable of giving instantaneous and time averaged results of aerosol concentrations. An LCD display has been combined with a microprocessor to provide a user friendly interface with clear and versatile presentation of data and menus.

The Microdust 880 represents probably the most versatile real time monitor available with an incredible measurement capability in one compact and easy to use instrument. The unit features calibration for zero and span calibrations ensuring it is easily maintained.

The 'Fab Four'
Tony Myles, Marketing Director for Casella CEL says:
" We have designed these four new I.S products to help employers meet increasing legislative requirements such as the Control of Substances Hazardous to Health Regulations 2002 (COSHH) and the Solvents Emissions Regulations 2004. The second reason is due to the many requests we've had from customers who work in potentially hazardous areas who need easy to use instruments to measure noise and air quality. So, we have taken the most popular instruments, famous for their robust design and simple operation and created I.S. versions so that they can be used in flammable environments. " We have designed these four new I.S products to help employers meet increasing legislative requirements. Now employers can comply with COSHH and the SED even in the most demanding hazardous environments.
"Because our new products meet so many needs, from legislation through to being user friendly in hazardous areas, we've coined them the 'Fab Four' as they will be music to the ears of many employers looking to meet their regulatory duties in a simple, easy to use and cost efficient way. This wide range of products also allows us to enter into an even wider arena of air and noise monitoring scenarios."
