Effortlessly check for leaks in your system using the Bykski Air Pressure Meter / Leak Tester. Simply attach the meter to a suitable stop cap point in your loop. Inflate the loop with air until the barometer needle reads at the appropriate reading. It is important not to exceed 0.5 Bar for systems with acrylic components, as this could cause damage to seals. For industrial/all metal systems inflate to 1.5bar. Once pressurized, the gauge should remain stable for approximately 10 seconds, confirming that your loop is free of leaks.
