Complete Monitoring of Electrical Parameters in a Single Device
This 3-in-1 digital indicator simultaneously measures voltage, current, and frequency in AC electrical installations, displaying the values on a green LED display visible from a distance. Ideal for electrical panels, generators, control panels, and industrial systems where continuous monitoring is needed without separate devices. It mounts quickly in a standard 22mm opening and comes with an included transformer coil.
What you get with this product
- Read 3 parameters on the same display — voltage, current, and frequency, without juggling multiple devices
- Excellent visibility in all conditions — green LEDs are clearly visible in both dark and bright light
- Universal mounting in a standard 22mm hole — compatible with most electrical panels and control panels
- Precise current measurement up to 100A — including transformer coil in the package, no additional purchases needed
- Continuous monitoring without high consumption — economical LED display, stable long-term operation
- Quickly check the status of the electrical network — detect voltage or frequency fluctuations before they become problems
How it works and how to install it
The digital indicator connects directly to the AC circuit to be monitored, and the included transformer coil clamps onto the phase conductor for current measurement. The display cyclically or simultaneously shows voltage (60-500V AC), current (0-100A), and frequency (20-75Hz). Installation is done in a 22mm opening in the electrical panel, and connections are made according to the provided diagram. Installation must be performed by qualified personnel, according to current electrical safety regulations.
Frequently asked questions
Can I use the indicator with a 220V single-phase network?

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
