Personal Air Sampling Pump and Sound Level Meter are a Hit Down Under with Australian Department of Defence
Following a competitive tender process, the Australian Department of Defence has taken delivery of 180 TUFF personal air sampling pumps and 180 CEL-350 dbadge personal sound level metres or noise dosimetres from Casella CEL (UK), global specialists in industrial hygiene and occupational health monitoring equipment.
Ronald Azar, Business Manager at Casella’s Australian distributor, Stantron, said: “Defence personnel were looking for pumps to measure air quality during training exercises and whilst working on Defence equipment. As a result they needed kit that offered sufficient charging capabilities to allow the pumps to operate continually away from mains power for at least 12 hours, as well as the ability to sustain simultaneous charging of all pumps. The TUFF pump met those requirements and more.”
The robust, Intrinsically Safe Casella pump features intelligent battery monitoring and fast/trickle charge control facility that maintains optimum battery condition and service life while fast charging. A remaining run time ‘fuel gauge’ is an additional benefit.
Featuring certification for use in locations where hazardous atmospheres may be present from flammable gases or dusts, the TUFF pump was an ideal choice for use in a military environment where safety is of primary concern.
The robust design of the Casella unit was a key point in its favour, since its ruggedness allowed Defence personnel to take it out into difficult environments in the field. It can be carried around easily by an individual or set up in a stationary location to carry out measurements.
Built for use in harsh environments, the TUFF is both reliable and cost-effective, making it accessible to individuals as well as organisations and government agencies wanting the assurance of accuracy in their measurements and reporting. In fact the Casella unit met Defence criteria of offering such accuracy that the flow rate could be measured to within +- 5%.
It was also important to Defence that both the TUFF pumps and dbadges were packed in cases that met the IP64 internationally recognized protection rating to ensure the greatest possible protection in the field and helping to ensure their longevity.
TUFF pumps feature an easy-to-use display with high intensity LED alarm for fault indication, plus an exceptional flow rate courtesy of an efficient double acting diaphragm mechanism with precise digital control. The digital, cable-free CEL-350 is lightweight at just 71g and accurately measures all occupational noise parameters, giving the time history of an individual's noise exposure throughout the day via a built-in graphic display. 149

Amidst growing concerns with the health effects of airborne particles, Air Monitors (UK), a specialist instrumentation company, is launching a new portable air sampler which significantly enhances the ability to measure and control biological contamination.
The ‘Coriolis µ’ has a new wet-walled cyclone technology that improves bioaerosol sampling for bacteria, pollen, endotoxins, viruses and fungal spores. Traditional techniques rely on the impact of biological particles on a solid growth medium, but the Coriolis µ collects the particles in a liquid at a high flow rate (300 l/m) with validated efficiency. The liquid containing the particles is compatible with a number of the latest rapid microbiological analysis methods.
The Coriolis µ offers advantages for sampling air with a high bioaerosol burden (which would saturate traditional solid media) because the liquid can be divided into multiple agar plates. This technology is also ideal for air with a low burden, because the Coriolis µ can collect for an extended period.
Air Monitors, Managing Director Jim Mills says “This is an exciting development and I think that as scientific knowledge in this area grows, it will become a standard method very quickly. In the meantime, I can see a wide variety of research and air quality investigation applications that would greatly benefit from this technology.”

A new probe is available for GrayWolf’s (USA) rugged, hand-held AdvancedSense HVAC/OH/FM/IAQ meters. The RH-AS2 probe is capable of measuring: Relative Humidity, Dewpoint, Absolute Humidity, Specific Humidity, Wetbulb temperature and Drybulb temperature.
This small diameter (14 mm, 0.6 inch Ø, 40mm, 1.6 inch L) probe may be directly connected to the AdvancedSense via the lower left 7 pin socket. It may alternatively be connected to an ACC-RH-HDLA (100mm, 4 inch L) handle with 1m cable for hand-held use and easy insertion into ducts. Humidity range is 0 to 100%RH (non-condensing) with accuracy of +/-2%RH.
When connected to an AdvancedSense meter that is outfitted with the optional BP-101 barometric pressure sensor, relevant moisture readings are auto-compensated for pressure changes due to altitude, meteorology, etc. The RH-AS2 may be used in conjunction with other probes for parameters including Differential Pressure, Air Velocity, Volume Flow, Carbon Dioxide, Carbon Monoxide, VOCs, Formaldehyde, Surface Temperature and many others. The AdvancedSense, with a colour touch-screen, also enables powerful features such as audio, photo and text note attachment to data-logged files, on-board video help and much, much more.
