Analogue Panel Instruments
We offer a comprehensive range of analogue and panel
instruments for use in control and instrumentation systems.
The range includes moving-iron and moving-coil mechanisms in
a variety of formats, scales and sizes. All our panel meters are
robust, accurate and constructed from high-quality materials to
give a long service life. Ammeters, voltmeters and power
meters are available with a large range of scales and can be
further customised for special applications.
