Import Battery Hydrometer — Buy in wholesale FOB from Supplier in China

The battery hydrometer offered by Yueqing Rhi Electic Co., Ltd. is a precision instrument designed to measure the specific gravity of electrolyte in lead-acid batteries, giving technicians direct insight into state of charge and overall cell health. The unit features an easy-to-read scale and a sturdy float mechanism housed in a protective casing, with an ergonomic, lightweight form factor that suits repeated daily use in workshop conditions. The supplier is located in Wenzhou, Zhejiang Province, a region with deep roots in electromechanical manufacturing, though the listing carries no response-rate or verification data that would indicate current trading activity.

Constructed typically from glass or chemical-resistant plastic with a weighted bulb and calibrated float, battery hydrometers of this class operate on Archimedes' principle, the float sinking deeper as electrolyte density drops with discharge. Specific gravity readings for a fully charged lead-acid cell usually fall between 1.265 and 1.285 at 25 °C, while readings below 1.200 suggest significant depletion. The protective casing mentioned in the source guards against breakage in oily or crowded workshop environments, and the ergonomic shaping reduces hand fatigue during batch testing of vehicle or forklift battery banks.

This instrument is purchased by automotive service centres, marine maintenance crews, golf-cart fleet operators, and renewable-energy installers who manage banks of flooded lead-acid cells. Buyers should confirm the exact scale graduation, whether temperature compensation is built in, and whether the unit includes a thermometer strip, as these details are not stated in the source. Trade terms such as MOQ, Incoterms, and lead time are absent from the listing and must be negotiated directly with Yueqing Rhi Electic Co., Ltd. before any order is placed.

Yueqing Rhi Electic Co., Ltd. is based at 7, Guang'an Road, Wuniu Town, Yongjia, Wenzhou, Zhejiang Province, 325603, China. The company operates within the Wenzhou electromechanical manufacturing cluster, an area historically concentrated in low-voltage electrical goods and automotive accessories. The listing's trust tier is marked 'harbor', but the response rate is shown as 0.00% with an average response time of zero hours, indicating no recorded buyer engagement through the platform and making direct outreach essential for any serious inquiry.

No employee count, annual revenue, factory size, or client references are provided in the source data, and none should be invented. The supplier's product focus appears to be battery testing and electrical equipment, though the breadth of their catalogue beyond this hydrometer is not disclosed. Buyers are advised to request a current company profile, quality-management certification status, and sample terms before committing to volume orders, given the absence of transactional history signals on this listing.
