About Beijing Channel Scientific Instruments Co.,Ltd. - Scientific Instruments Supplier in China

Based in Beijing, China, Beijing Channel Scientific Instruments Co.,Ltd. lists 31 distinct products in its catalogue. The portfolio spans soil testing and surveying instruments, general scientific instruments, and related tools such as agricultural sprayers and farm machinery accessories. Product titles include the QT‑SM01 Soil Moisture Meter, QT‑PH350 Soil pH Meter, QT‑WMS Series handheld Weather Station, and QT‑1 Laser Particle Size Analyzer, each falling under HS chapters 9025‑9027 for measuring and testing equipment. The catalogue also features flow measurement devices like the QT series tipping bucket flowmeter and plant analysis systems such as the QT‑LS02 Leaf Analysis System.

The supplier’s offerings cover portable and bench‑top devices for measuring soil water potential, temperature, humidity, CO₂ concentration, and leaf chlorophyll, as well as accessories like the QT‑TQ0401 PR2 Probe Installation Tool Kit. Instruments are designed for field use in agriculture, environmental monitoring, and research laboratories. The range includes battery‑operated handheld units and larger laboratory systems such as the QT‑RWC Root Washing System. No specific certifications are listed for the company, so buyers typically verify CE marking, ISO 9001 quality management, and calibration certificates for precision instruments.

Product Range and Specialties of Beijing Channel Scientific Instruments Co.,Ltd.

The catalogue contains soil moisture meters (QT‑SM01, QT‑SM100, QT‑ML3) that usually provide accuracy of ±3 % volumetric water content and operate from - 20 °C to 60 °C. Soil pH meters (QT‑PH06S/30S, QT‑PH350) are typically calibrated to a 0‑14 scale with an accuracy of ±0.01 pH units. The QT‑1 Laser Particle Size Analyzer employs laser diffraction to cover particle sizes from 0.1 µm to 2 000 µm, a common specification in laboratory particle analysis. Flowmeters in the QT series are tipping‑bucket types capable of measuring rainfall or irrigation flow up to 200 mm h⁻¹, often packaged in ABS housings with stainless‑steel sensors. Handheld weather stations (QT‑WM Series) normally record temperature, humidity, wind speed and direction, and may include CO₂ sensors with a range of 0‑5 % and accuracy of ±50 ppm. All devices are typically supplied with anti‑static foam packaging and can be palletised for container loading.

Trade and Export Information - Beijing Channel Scientific Instruments Co.,Ltd.

China is a global exporter of scientific and agricultural measurement instruments, with HS codes 9025 (instruments for measuring or testing), 9026 (instruments for measuring temperature, humidity, pressure), 9027 (instruments for measuring pH, conductivity) and 9024 (flow measurement devices) covering most of the products listed. Major import markets include the United States, the European Union, Japan, South Korea and Australia, where buyers in agronomy, environmental consulting, and research institutions regularly source such equipment. Commonly required certifications for these categories are CE marking for EU markets, FCC certification for the United States, ISO 9001 for quality management, and ISO 17025 calibration reports for high‑precision meters. Export shipments are usually packed in 20‑ft or 40‑ft containers, with handheld units loaded at an average density of 500‑800 units per container, while larger bench‑top systems are palletised on wooden crates. Typical Incoterms used by Chinese instrument exporters are FOB Shanghai or CIF destination port, with temperature‑controlled containers rarely needed but moisture‑proof packaging standard.

Sourcing from Beijing Channel Scientific Instruments Co.,Ltd. - Buyer Guidance

Prospective buyers should request a current CE Declaration of Conformity, any applicable FCC statements, and an ISO 17025 calibration certificate for each measuring device. Product datasheets should confirm measurement range, accuracy, power requirements (e.g., 3.7 V lithium‑ion battery life of 8‑10 hours for handheld meters) and environmental durability (IP‑rating where relevant). It is advisable to obtain a functional sample before committing to larger volumes, especially for devices with sensor probes such as the QT‑RWC Root Washing System. Typical minimum order quantities are 50‑100 units for handheld meters and 10‑20 units for larger laboratory systems; lead times range from 30 to 45 days after order confirmation, subject to component availability. Verify packaging details - anti‑static foam, moisture‑resistant pallets, and clear labeling of HS codes - to ensure smooth customs clearance.
