Air Testing


	RAWSEN is pleased to offer the AQT4 compressed air analyzer, the flow meter and the leak locator to help you maintain an efficient compressed air system.



	Innovative Air Quality Tester for Compressed Air The AQT4 is a unique “4-in-1” compressed air analyzer - the first of its kind on the market. It measures mass concentration of contaminants, temperature, pressure and pressure dew point of compressed air. The portable AQT4, weighing only 7 kg, can measure in the following ranges:.

	Pressure : 130 to 1000kPag Temperature : -30 to 79°C Dew point (P) : -45 to 27°C Particle count : 0,0001 ppmw to 59 ppmw



	The AQT4 reports output data on an on board LCD display and also directs data to a PC from which a graphical and tabular data report may be printed. The AQT4 will enable Rawsen to provide a customer with a detailed report on the state of his compressed air or a verification on an installation that the compressed air quality conforms to a given standard.


	Flow Meter The flow meter measures the flow of compressed air at system pressure. Data is logged for download to PC and it can be used in pipelines from 50mm in outer diameter.


	Leak Locator The ultrasonic leak locator is used to identify compressed air leaks. When leaks are found, they are flagged for later tightening or repairing. Removing leaks saves compressed air and results in a reduction of energy costs.
