MYA 4Y.F microbalance and UYA 4Y.F ultra-microbalance are equipped with new stainless steel chamber for filter weighing. The material makes the chamber more resistant to chemicals, colour change and scratches. Innovative disassembly system facilitates chamber cleaning. Its lid is partly made of glass therefore the operator can observe the filter and make sure that it remains in the same position after chamber closing. The chamber is a highly hermetic solution, and the large weighing pan intended for filters allows precise measurement of filters of various sizes.
