High-accuracy DC/AC Voltage Current Resistance Tester Digital Multimeter Meter
Introduction:
- TH1942 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, TH1942 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.
- The instrument is equipped with SMD component inside to reduce density and physical size.
- The instrument comes standard with RS232C (OPTIONAL) communication interface and common communication software is optional to meet the need of communication with computer, data analysis and statistics, and building up automatic test system. The instrument accepts SCPI command to ensure compatibility of communication software.
