Similar to Newton Meters but along with the suspension ring at the top and load hook at the bottom for pull type loading, it also has a plastic rod with rectangular cross-section at the top for push type loading of the balance. This bar extends to inside the clear acrylic tube and guides the tempered steel spring, which is always loaded compressively due to loading either at top or bottom i.e., push or pull respectively.
The reading scale is calibrated in both kg and Newton and a plastic cursor inside the tube registers push/ pull reading.

Set of 6 (one of each capacity): 250g/2.5N; 500g/5N; 1kg/10N; 2kg/20N; 3kg/30N; 5kg/50N
