17. ADDITIONAL ECQUIPMENT 
Anti-vibration table 
 
 
It is a very stable basis which eliminates all kinds of vibrations and ground shakes. 
The inner part of the table holds a marble plate, which is a foundation for balance 
positioning. 
 
 
 
 
Rack for under-pan weighing  
 
 
The rack is used if under pan weighing option has to be applied. Under pan weighing 
is necessary if magnetic loads are weighed or during density determination of 
substances. Racks are also used for measuring absorptiveness of substances e.g. 
foamed polystyrene. The rack is made of mild steel. Rack height is 330mm. 
 
 
 
 
Density determination kit (for solids and liquids) 
It is applicable with balance with resolution at least 1 mg. designed for density 
determination of solids and liquids. The procedure is fully automatic, i.e. the user 
only places samples on kit’s weighing pans.  
 
 
 
Additional display 
 
 
 
Features: Length of cable between additional display and balance – 1,5m, plastic 
casing, with tilting option. 
 
 
 
 
 
 
 
 
 
 AP2-1 current loop 
Current loop module 4-20mA of RADWAG production is intended for conversion of 
digital form of weight indication to analogue value. AP2-1 comprises plastic 
housing. It is powered with an external 230V/5VDC power adapter. Both, AP2-1 
and power adapter are a set. Current circuit is fed through 1,7-meter long 2-wire 
cable.
