Air quality monitor AEROTEST SIMULTAN

Increasing damage to the environment and enforced regulations for breathing air quality such as DIN EN 12021 mean that the requirements to be met by the operators of filling stations are getting stricter all the time. With the AEROTEST SIMULTAN HP portable breathing air tester to measure cleanliness, you will always be on the safe side! Tester tubes simultaneously and accurately measure compliance with the concentration limit for CO, CO2 and water vapour in the compressed air. An "impactor" is used for simultaneous verification of mineral and synthetic oil content in the breathing air. The breathing air tester has been to all but exclude the risk of incorrect measurements as a result of operator error. The device does not have to be calibrated either. A pressure reducer and special nozzles keep volume flow constant at all times, thereby safeguarding consistently accurate measurements. The AEROTEST SIMULTAN HP breathing air tester checks for compliance with the limit values specified in standard DIN EN 12021¹ for breathing air¹, thereby providing effective protection for life, health and equipment. The measuring principle (verification of oil content) Compressed air flows through the 20 nozzles of the impactor and vertically hits a baffle plate made from cut glass. On account of the air being deflected 90° in the impactor, the aerosol particles are unable to follow the airflow due to their inertia and are separated on the glass plate. The indentations in the cut glass are filled with oil, counteracting the light scattering caused by the cut glass. This principle provides a visual indicator of very low oil quantities.
