The Extech 380926 is a category IV, 2000-Amp, TRMS AC/DC clamp meter with a rugged 2 in. jaw to accommodate two 500 MCM cables. A built-in full-function DMM can measure AC/DC voltage and current, resistance, capacitance, frequency, duty cycle, diode and continuity. Measurements are displayed on the large 4000 count backlit display for easy viewing in dimly lit areas. Additional features include DCA push button zero, Data Hold, and Relative function. Complete with test leads and 9V battery.
The compact Extech 380941 is a 200 Amp mini AC/DC clamp meter with a small diameter jaw designed to reach in small areas while providing 10mA resolution (DC) and very low-current sensitivity. This mini clamp meter is useful for troubleshooting tasks in plant maintenance, electrical, HVAC, and telecom work, as well as home electrical, fleet maintenance, marine, and motorcycle repairs. The 380941 has a CAT III 300-Volt safety rating and a one year warranty. Comes with batteries and manual.
The compact Extech 380942 is a 30 Amp mini AC/DC clamp meter. The clamp meter has a remarkable 0.1mA resolution (AC), very low-current sensitivity, and a small diameter jaw designed to reach into small areas. The 30 Amp range with 0.1mA (AC) and 1mA (DC) resolution is optimized for finding problems where very low current variances would be missed by standard clamp meters. This mini clamp meter is useful for troubleshooting tasks in plant maintenance, electrical, HVAC, and telecom work, as well as residential electrical, fleet maintenance, marine, and motorcycle repairs. This CAT III-rated True RMS mini clamp meter comes with test leads, 2 AA batteries, soft carrying case, and user manual.
The compact Extech 380947 is a 400 Amp True RMS mini clamp meter. This meter has a small diameter jaw designed to reach in small areas while providing 1mA resolution and very low-current sensitivity. This mini clamp meter is useful for current and frequency related troubleshooting in plant maintenance, electrical, HVAC, and telecom work, as well as home electrical, fleet maintenance, marine, and motorcycle repairs. Comes with battery and manual.
