They are ideally suited for maintenance and repair work in industry, service sectors, electrical engineering, and electronics. With their integrated shockproof casing and IP67 protection rating, they are particularly robust and reliable in all environmental conditions. The measurement type of the DMM 210 and DMM 220 multimeters is AVG, while the measurement type of the DMM 230 and DMM 240 multimeters is TRMS. The DMM 240 multimeter measures DC and AC voltages, DC and AC currents, frequencies, capacitances, temperatures with a supplied K-type thermocouple probe, and resistances. Additionally, it can determine diode voltage and continuity with a buzzer. Thus, it includes all the classic measurement functions of a multifunctional multimeter. The backlit display with 40,000 digits and bar graph ensures excellent readability.
