STA9941/STA9942 Series Digit Multimeter

STA9941 4 1/2-digit true-RMS digital multimeter and STA9942 50,000-count digital multimeter are voltage,current,resistance tester with multi functions and low cost. The instrument can stably perform measurement at high speed as several times as competitive instruments in this class. It provides excellent performance, such as maximum reading of 21,000/51,000 counts, maximum DC voltage accuracy of 0.02%, and low cost to give you a best choice.

Having VFD dual-display with high brightness, STA9941/STA9942 can synchronously display measurement parameters, such as AC/DC voltage or current, AC voltage/current and frequency to improve measurement efficiency and display results clearly.

** Standard Lead Time: within 4 weeks **
