CASELLA, an air sampling, noise and vibration monitoring specialist reports it has introduced the Flow Detective air sampling pump calibrator and says the product is the first in the industry with the ability to measure pulsation, with a 70-hour battery life; the longest on the market and double the duration of competitive products.
There is an estimated 18,000 new cases of lung problems a year caused or made worse by work, and an estimated 12,000 deaths from lung diseases linked to exposure at work. It is an employer’s duty to protect the health of employees through health surveillance and exposure monitoring. Casella says air sampling is crucial and its latest Flow Detective is a robust solution allowing air sampling pumps to be calibrated, ensuring the pump has the correct flow, with traceable measurement results.
