With the pressure set accessory, all Medio-Line & Macro-Line Scales can be easily transformed into a force gauge within seconds. Drag the pointer for maximum load indication per measurement included. The lower suspension can be easily removed if not needed. We've created kits combining the two products to simplify your shopping experience and offer you the flexibility to measure the opening and closing force of elevators, lift doors and fire/panic/emergency exits and much more! The level of substance within a container (ie: Fire extinguisher) can be measured as well.
