Since yung poster ay taga Marikina it seems na walang may ganitong equipment malapit sa kanyang vicinity, or yung mga shop within Metro Manila.

Just to answer this inquiry, meron akong alam kaya nga lang it is Outside Metro Manila, sa Quezon Province kasi yung shop nila, actually kaibigan ko yung may ari so I ask his permission to post this picture.



Yung nasa left side ng picture ay weighing scale, they charge refrigerant by weight at the right side naman yung ang kanilang leak detector (Yokogawa H10PM) at the back is a nitrogen tank. They use dry nitrogen to pressurized the system for testing its integrity and to avoid introducing too much moisture.
