The HK888 Flexible Current Sensor is a high-performance current measurement accessory designed to extend the capability of digital multimeters and clamp meters.
It works by measuring AC current and converting it into a proportional voltage signal, which is then transmitted to the connected meter for accurate display.
With a maximum measurement capacity of 3000A AC, this flexible sensor is particularly suitable for photovoltaic systems, industrial installations, and complex electrical environments where traditional rigid clamps cannot be applied.
