yes. a sniffer will find the leak.
however, putting a new dryer in a system with unknown tightness under vacuum, is unwise. the best and only effective way to test for leaks is with pressure.
you should pressurize the system below vapor pressure of the gas, and either verify the pressure does not drop for 24 hours, or search out the leak with a detector, either bubbles or electronic detector.
