JWF LK 20 Leak Calibrator
	For quick precise checking, adjustment and calibration of leak testers. Small and handy, light and independent of mains, the LK 20 is suitable for quick and precise calibration in production and for quality control: Direct display of leakage rate in cmł/min Instantly available result of measurement Measured value independent of atmospheric pressure and temperature Suitable for high pressure and vacuum leak testers
Mode of operation The JWF FROEHLICH LK 20 leak calibrator works by the air mass flow rate measuring method. The adjustable precision restrictor is simply connected to the quick-action coupling of the leak tester. The leaking air flows directly to the sensor. The leakage rate set at the restrictor is immediately displayed as the mass flow rate digitally in cmł/min on the LCD.
