The Yokogawa CL200 Series clamp-on testers are designed for accurate AC and DC current measurement in conductors ranging from 24mm to 55mm in diameter. The series includes four models with varying measurement capabilities to suit different applications, all featuring lightweight, compact construction for easy portability.

CL220 is a compact 300A AC/DC clamp meter with 24mm jaw opening. It features mean value detection with 40/300A DC ranges and 40/300A AC ranges, 0.01A resolution on the 40A range, and frequency response of 20Hz to 1kHz. It meets EN61010-1 and EN61010-2-032 safety standards.

CL235 offers True RMS measurement with 33mm jaw opening. DC current ranges are 400/1000A with 0.1A resolution, while AC current ranges are 400/600A with frequency response of 40Hz to 1kHz. It includes AC/DC voltage, frequency measurement, and meets EN61010-2-031 and -032 standards.

CL250 provides 2000A AC/DC measurement with 55mm jaw opening using mean value detection. It features 400/2000A DC and AC ranges, AC/DC voltage measurement, and recorder output function. It meets EN61010-2-031 and -032 standards.

CL255 delivers 2000A True RMS measurement with 55mm jaw opening. It offers 400/2000A DC and AC ranges, AC/DC voltage measurement, frequency measurement, and recorder output. AC frequency response is 30Hz to 1kHz. It meets EN61010-2-031 and -032 standards.

All models feature a 3999-count LCD display, data hold function, sleep function to conserve battery life, and 2-second typical response time. Each unit includes test leads (where applicable) and a protective carrying case.
