General Description

The SINOTIMER D85-2058 is a multifunctional digital measuring instrument for measuring electrical parameters in single-phase AC networks. The device simultaneously displays voltage, current, active power, frequency, power factor, and energy consumption (kWh), making it ideal for monitoring consumption in homes, laboratories, or industrial applications. Equipped with a high-visibility LCD screen, it includes a current transformer for accurate measurements.
