Nokeval 201 & 202 Loop Powered Panel Meters

£173.00 – £202.00

The Nokeval 201/202 Loop powered bright red LED-display needs no external power supply – the current signal 4-20 mA loop provides the necessary energy. Therefore, it is possible to install the meter in places with no auxiliary power available. You can now replace auto-powered LCD-displays by bright red LED-displays.
