About Systester - Electric Testers Supplier in China

China hosts Systester, which currently lists 12 active products across four categories: Electric Testers, Agriculture, Light & Medium Machinery, and Wires & Cables. The catalogue includes a variety of permeability, tensile and leakage testing instruments that are classified under HS Chapter 90 (instruments and apparatus for measuring or checking). Each entry is identified by its functional name rather than a model number, showing the supplier’s focus on laboratory‑type testing equipment. The product set spans air, gas, water‑vapor and oxygen permeability testers, as well as tensile and leakage testers for plastics and other materials.

The listed items cover both standard ASTM‑type tensile testers and specialized permeability devices such as the HSL‑6001 Heal Seal Tester and the LEAK‑5001 Leakage Tester. Although the facts do not include HS‑code details for individual models, the overall product family aligns with HS codes 9026 (instruments for measuring pressure) and 9027 (instruments for measuring physical characteristics). Systester’s portfolio therefore represents a niche segment of Chinese manufacturers supplying analytical equipment for quality control and research applications.

Product Range and Specialties of Systester

The catalogue features air‑permeability testers (e.g., Systester Air Permeability Tester, Gtr‑7004 Air Permeability Tester), gas‑permeability units (Oxygen / Gas Permeability Tester, Oxygen Permeability Tester), water‑vapor permeability testers, and a range of tensile and leakage testers for plastics and other substrates. In the testing‑equipment industry, air‑permeability instruments are typically specified by flow rate in cm³/s·cm² under a defined pressure differential (often 100 Pa). Gas‑permeability devices are rated by permeability coefficient (Barrers) and may comply with ASTM D3985 or ISO 15105. Tensile testers for plastics are commonly rated up to 200 kN load, with crosshead speed control in the 0.01 - 500 mm/min range, and are calibrated according to ASTM D638 or ISO 527. Leakage testers are usually expressed in leak rate (mbar·L/s) and must meet ISO 20485 for leak detection accuracy.

Trade and Export Information - Systester

China is a major exporter of laboratory and industrial testing equipment, with the majority of shipments routed to Southeast Asia, Europe and North America. Products in HS Chapter 90 are typically cleared under the Harmonized System codes 9026‑90 and 9027‑90, and customs authorities often request CE marking, ISO 9001 quality‑management certification and, where applicable, ISO 17025 calibration certificates. Buyers usually prefer FOB or CIF terms, and the instruments are packed in wooden crates or reinforced cardboard boxes to protect delicate sensors and calibration standards during 20‑foot or 40‑foot container transport. Export documentation frequently includes a test‑equipment declaration, a conformity‑of‑type certificate, and a detailed packing list specifying unit weight (often 10 - 150 kg per tester).

Sourcing from Systester - Buyer Guidance

When sourcing from Systester, buyers should request the latest calibration certificates for each tester, confirming compliance with the relevant ASTM or ISO standard cited in the product description. It is prudent to ask for a functional demo video or a sample unit, especially for permeability testers where chamber size and flow‑meter accuracy are critical. Verify that the supplier can provide CE declaration and, if required by the destination market, an ISO 17025 laboratory accreditation report for the measurement system before finalizing the order.

What types of permeability testers does Systester offer?

Systester lists air‑permeability, gas‑permeability (including oxygen), water‑vapor permeability and combined oxygen/gas permeability testers. Each model is designed for laboratory use and is classified under HS codes 9026‑90 or 9027‑90.

Which standards apply to the tensile testers in the catalogue?

The universal tensile tester of plastic and the Auto Tensile Tester ASTM are referenced to ASTM D638 and ISO 527 for plastic specimens. Load capacity typically ranges up to 200 kN, with crosshead speed control in accordance with those standards.

What documentation should a buyer request before purchasing a leakage tester?

Buyers should ask for the LEAK‑5001 Leakage Tester’s calibration certificate, a CE declaration of conformity, and any ISO 20485 test‑method validation report that demonstrates leak‑rate accuracy.

Are there typical HS codes for the listed testing equipment?

Testing instruments of this type are generally recorded under HS Chapter 90, specifically codes 9026‑90 for pressure‑measuring devices and 9027‑90 for instruments measuring physical characteristics such as permeability and tensile strength.

What packaging and shipping formats are common for these testers?

Exporters usually pack the units in reinforced wooden crates or double‑wall cardboard with foam inserts. Standard container loads are 20 ft or 40 ft containers, with each tester weighing between 10 kg and 150 kg depending on size.

Which certifications are typically required for importing these testers into Europe?

European importers commonly require CE marking, a Declaration of Conformity, and, for calibrated equipment, an ISO 17025 laboratory accreditation certificate. Buyers should verify that these documents are supplied by the manufacturer or an accredited third‑party laboratory.
