Import Dt830b — Buy in Bulk from Supplier in China

The DT830B is a digital multimeter designed for basic electrical testing, featuring a 1999-count display and a 9V battery power supply. It measures DC voltage from 200 mV to 1000 V with a stated accuracy of 0.5% + 2 digits, and AC voltage from 200 V to 750 V with 1.2% + 10 digits accuracy. DC current ranges from 200 µA to 10 A with 1% + 2 digits precision, and resistance spans 200 Ω to 2 MΩ with 0.8% + 2 digits tolerance. It includes diode and transistor testing functions.

The device is housed in a compact case measuring 126 x 70 x 24 mm and weighs 150 g net. The display size is 16 x 48 mm, optimized for readability in low-light conditions. It is available in yellow and black color variants, with standard accessories including test leads, a battery, and a printed manual. The product is built for field use and educational environments, not industrial calibration labs, and lacks auto-ranging or data logging features.

Buyers include electronics repair shops, vocational schools, and small-scale maintenance teams in Asia, Africa, and Latin America. The product is typically shipped in bulk cartons of 50 to 100 units, packed with foam inserts and labeled for customs clearance. Packaging does not include branded retail boxes.

Zhangzhou Weihua Electronic Co., Ltd is located in Beidou Industrial Park, Jinfeng Industry, Zhangzhou, Fujian Province, China. The supplier is classified as an imported-tier business with harbor-tier trust status, indicating it has completed basic export compliance checks. There is no public information on years in operation, workforce size, or manufacturing capacity. The listing does not mention ISO certification, product testing labs, or quality control procedures.

The company appears to function as a manufacturer or assembler of low-cost electronic test instruments. No claims are made about OEM services, custom firmware, or compliance with international safety standards. The absence of response rate data suggests limited customer service capacity. Buyers should request product compliance documentation and test reports directly, as these are not provided in the listing.
