N260 Full Range Tonnage Monitor
The PressWatch N260 Series has earned a reputation for the highest quality, most accurate and complete
production monitor on the market today. It has a full range of features that provide excellent press,
die and part monitoring.
The N260 production monitor can be used alone or with a computer for networking and signature analysis.
It has a serial port to easily network monitors for comprehensive production information at one central PC.
The N260 functions without a computer to provide the traits of a tonnage monitor plus the benefits of a
production monitor.
