Import Change Oil By Quality — Buy in Bulk from Supplier in China

The THY-22B oil quality analyzer evaluates lubricant contamination within three minutes, measuring a range of ±199.9 units and detecting metal particles larger than 60µm. It reports repeatability of 2% and operates between -20°C and +85°C, powered by a 0.2W DC supply from four AA 1.5V batteries. The device weighs 0.8kg and measures 183×96Ù38mm, making it portable for field use. Its core function is to confirm whether newly purchased lubricants meet required standards.

The analyser employs optical-sensor technology common in oil-analysis equipment, delivering typical accuracy of ±6.0% in laboratory conditions. Standard industry devices in this class also feature a temperature-compensated measurement circuit and a battery life of several hundred tests per charge. The compact housing is constructed from engineering-grade polymer, providing resistance to oil splashes and ambient dust. Compared with typical handheld lubricants testers, the THY-22B offers a broader detection range and faster response time.

Primary users include maintenance teams in aerospace, oil-field operations, ports, transport fleets, mining, power generation, metallurgy, chemical plants and engineering facilities. Importers can request bulk units under FOB or CIF terms, though exact MOQ and lead time must be confirmed with the supplier. The device is suited for both on-site monitoring and laboratory verification, allowing buyers to integrate it into preventive maintenance programmes. Payment and shipping conditions follow the supplier’s standard international trade practices.
