## Long description

ORNO OR-WAT-435 is a compact wattmeter with a built-in LCD display designed to monitor active power in small installations and portable equipment tests. The device measures power within the mid-range band and presents readings on a clear screen, while its button control lets the user configure basic settings. With a narrow housing and modest depth and height, the wattmeter is intended for applications that require straightforward power diagnostics without occupying much space.

The instrument provides precise mid-range power measurement in a compact enclosure suitable for limited-space environments. Its integrated LCD display gives immediate visual feedback of real-time power values, and the button control enables simple setting adjustments without tools. The device’s dimensions allow mounting in distribution boxes or placement near tested equipment, simplifying workflows in installation verification and energy checks.
Suitable for
 Monitoring power consumption of small electrical appliances and devices

How to use
Connect the wattmeter according to the electrical installation practice applicable in your region, ensuring the device is placed near the load or within the distribution area to be monitored.
