About Ym Instrument Co.,Ltd. - Scientific Instruments Supplier in China

China‑based Ym Instrument Co.,Ltd. lists seven active products across four categories: Scientific Instruments, Soil Testing & Surveying Instruments, Temperature Controllers & Indicators, and Touch Screen/LCD Monitors. The catalogue includes items identified as Cf truncheon, Nutra‑dip continuous tri meter ym‑2006a, Ph meter, Temperature test meters monitoring, Ph truncheon, Ph, tds and temperature meter, and Ph‑messer (ph tester). Each entry falls under the broader HS Chapter 90 family for electronic measuring devices, which is standard for laboratory and field instruments exported from China. The supplier is classified as an imported tier with a harbor trust rating, indicating it operates through established trade channels without direct manufacturing claims.

The listed instruments are primarily pH, TDS and temperature measurement devices. Typical pH meters in this segment offer a measurement range of 0‑14 pH units with an accuracy of ±0.01 pH and temperature compensation between 0 °C and 50 °C. TDS meters commonly measure up to 9 999 ppm with a repeatability of ±2 %. Temperature monitoring meters usually cover - 10 °C to 110 °C with an accuracy of ±0.5 °C. These specifications align with standard requirements for agricultural, environmental and process‑control applications where Ym Instrument’s products are positioned.

Product Range and Specialties of Ym Instrument Co.,Ltd.

Ym Instrument’s catalogue features two pH‑focused devices (Ph meter, Ph‑messer), a combined pH/TDS/temperature unit (Ph, tds and temperature meter), and dedicated temperature monitoring meters. In the broader market, pH meters are supplied in glass‑electrode and solid‑state formats, with calibration buffers at pH 4, 7 and 10 being standard. TDS meters often incorporate automatic temperature compensation (ATC) and use a 4‑wire probe design. Temperature controllers and indicators typically conform to IEC 60730 safety standards and may include LCD or touch‑screen displays for real‑time readout. Although the supplier lists touch‑screen/LCD monitors as a top category, the current product set focuses on handheld meters rather than larger display panels, which is common for field‑use scientific instruments.

Trade and Export Information - Ym Instrument Co.,Ltd.

China is a major exporter of electronic measuring instruments, and products classified under HS 9025 (electrical measuring, testing and precision instruments) are routinely shipped to Southeast Asia, the Middle East, Europe and North America. Buyers in agriculture, water‑treatment, environmental monitoring and food‑processing sectors frequently import pH, TDS and temperature meters from Chinese manufacturers. Typical export documentation includes a commercial invoice, packing list, CE conformity declaration and, where required, an IEC‑type test report. Containers of 20 ft can accommodate roughly 2 000 handheld meters, packed in anti‑static bags and double‑wall cardboard boxes to protect against moisture and static discharge. Incoterms such as FOB Shanghai or CIF destination port are commonly used, and importers often request pre‑shipment inspection reports to verify compliance with IEC 61010 safety standards.

Sourcing from Ym Instrument Co.,Ltd. - Buyer Guidance

When sourcing from Ym Instrument, buyers should request the latest CE declaration and any ISO‑9001 quality‑management certificates that the supplier holds. A calibrated certificate of accuracy for each meter model, together with a test report showing compliance with IEC 60730 (for temperature devices) or IEC 61010 (for measurement instruments), provides a baseline verification. Samples of the pH probe material (glass or solid‑state) and the TDS probe assembly should be examined for durability and ease of cleaning. Typical minimum order quantities for handheld meters range from 100 to 500 units, and lead times reported by similar Chinese exporters are 30‑45 days after order confirmation. Buyers should also confirm packaging details - anti‑static inner bags, sturdy outer cartons, and palletization for sea freight - to ensure safe transit.
