The HK588B is an upgraded 2000-count True RMS clamp meter built for technicians who need more accurate AC readings and added temperature measurement. It measures AC current up to 600A, AC/DC voltage up to 600V, resistance up to 20MΩ, and temperature from -20°C to 1000°C / 0°F to 1832°F, making it suitable for electrical, HVAC, motor, and equipment maintenance tasks.

Compared with the HK588A, the HK588B adds True RMS capability and temperature testing, while its LPF ACA function supports AC current checks in systems affected by variable-frequency drive noise. Combined with NCV, live wire recognition, diode test, continuity buzzer, flashlight, data hold, MAX reading, and a backlit LCD, it is a more complete tool for demanding service environments.
