Import Dynamic/Static Ionic Contamination Tester Lz22 — Buy in Bulk from Supplier in China

The Dynamic/Static Ionic Contamination Tester LZ22 is a laboratory instrument designed to measure ion contamination on bare PCB boards and assembled PCBA before and after cleaning or coating processes. It operates in both static and dynamic modes, houses a water tank of roughly 15 L (352 mm × 70 mm × 600 mm), draws 1300 W of power from an AC 220 V 50 Hz supply and weighs about 115 kg, making it suitable for medium‑size test labs. The machine can accommodate test areas from 10 cm × 20 cm up to 35 cm × 60 cm, covering board sizes of 1000‑4200 cm².

The tester uses an online high‑precision conductivity meter together with mixed anion‑cation exchange resins and temperature‑compensation algorithms to deliver a conductivity resolution of 0.001 µS/cm and a measurement range of 0.0001‑20 µS/cm (NaCl equivalent 300‑100 000 µg). Test accuracy is stated as ±5 % and the electrode resolution matches the same range. Typical industry practice aligns such equipment with IEC 61340‑5‑1 for electrostatic discharge control, although the listing does not confirm certification.

End users include PCB manufacturers, contract electronics assemblers and quality‑control laboratories that need to verify cleaning effectiveness and prevent conductive contamination. The instrument can be customised in water‑tank volume on request, and buyers should confirm minimum order quantities, lead‑time and preferred Incoterms directly with the supplier. Payment terms and inspection arrangements are negotiated per transaction, and any required certification documents should be requested before purchase.

Guangdong Zhengye Technology Co .Ltd is located in Dongguan, Guangdong Province, China (postal code 523808). The company is listed with a harbor trust tier and currently shows a zero percent response rate, indicating that enquiries may require follow‑up through the platform’s messaging system.

The supplier markets laboratory testing machines such as the LZ22 and offers customisation of water‑tank volume and software parameters. No specific certifications, production capacity or client references are disclosed in the listing, so buyers should request any needed documentation directly from the supplier.
