Product information
Details
BS74 clamp meter can measures AC/DC current up to 1200A, with AC/DC voltage, resistance, continuity, diode, capacitance and frequency. It also has TrueRMS (TRMS) function, frequency response extended to 1kHz. Simplifies the analysis of complex AC signals. The large 3 4/5 digits digital LCD display (6600 counts) with backlight and LED torch permits an easy readability also in dim light conditions. The instrument is complying with IEC/EN61010-1, CAT IV 600V and it is designed for required high safety and high accuracy measurement both in domestic and industrial environments use.
