Increasing automation, an expanding electronics industry and global initiatives on energy efficiency have emphasized the need for accurate electrical measurements. These trends, in turn, will continue to boost the demand for digital multimeters (DMMs) and encourage more technological innovations in these devices.
The largest production base for these instruments, with a 35 percent share globally, is China, according to QY Research. In recent years, Chinese manufacturers have introduced DMMs with high accuracy, multiple functions and value-added features.
One supplier interviewed by Global Sources, Shenzhen Everbest Machinery Industry Co. Ltd, has a LAN tester and a digital multimeter in one device, with a built-in speaker on the probe for audible feedback. This unit has RJ-45 and RJ-11 connectors.
Widely available DMMs in China can measure AC/DC voltage, current, capacitance, resistance, inductance, frequency, temperature and other parameters. Most companies ensure these products meet UL, CE, CSA, VDE, TÜV, IEC and RoHS standards.
Chinese companies usually use passive components, filters, circuit breakers, AC/DC converters, PCBs, displays and cases sourced within the country. So far, the cost of these inputs is expected to remain relatively stable and keep DMM prices unchanged until the end of 2024.
