Customized to Your Needs

Upon special customer request, the indicators can be customized to include an additional current output of 0 to 20 mA, except for specific types.

To accommodate specific requirements, the response threshold for the input signal, display settings, and current output can be easily adjusted using a small 2 mm screwdriver, with plastic plugs conveniently located at the rear of the meter.

This level of adjustability ensures optimal functionality and performance for different measurement applications.

Why Analog Displays Are Still Widely Used

Simple and clear readability remains the key reason for the continued use of analog display instruments, ranging from dial gauges and rotating symbols (stepper motor-driven) to externally voltage-independent speed indicators with moving coil mechanisms.
