The PM8000 Series digital panel meters are easy to set up and commission, whilst offering extremely high precision and long term reliability.

A MENU-FREE calibration system is employed with this panel meter design. This makes calibration and set-up of operating parameters very straightforward and radically simplifies this process compared with the usual menu arrangement used on most digital meters. The menu in this case is replaced by simple push buttons enabling zero, span, analogue output or alarms to be adjusted via buttons on the front of the panel.
