About Doaho Test Company Co., Ltd. - Agriculture Supplier in China

Doaho Test Company Co., Ltd. is based in China and currently lists eleven active products in its catalogue. The company’s portfolio focuses on environmental and reliability testing equipment rather than agricultural goods, despite being classified under the Agriculture category. Each product is presented as a distinct type of test chamber designed for controlled laboratory conditions. The catalogue includes chambers for temperature, humidity, vibration, rain, sand and dust, as well as specialized Xenon lamp and ultra‑aging units. These items are generally grouped under the HS code family 8479 for testing apparatus.

The listed chambers cover a range of configurations, from benchtop units to larger reach‑in models. Product titles such as “Temperature Vacuum Test Chamber” and “Rain Test Chamber” indicate capabilities for low‑pressure thermal cycling and simulated precipitation, respectively. The “Sand & Dust Test Chamber” suggests compliance with dust‑ingress testing standards. The inclusion of “Temperature Rapid Change” and “Temperature & Humidity Rapid Change” chambers points to fast‑response temperature‑humidity control. All eleven entries are captured without additional product specifications in the supplied data.

Product Range and Specialties of Doaho Test Company Co., Ltd.

The catalogue comprises eleven chamber types: Xenon lamp test chamber, temperature‑vacuum chamber, vibration chamber, alternating temperature chamber, rain chamber, ultra‑aging chamber, benchtop chambers, reach‑in chamber, temperature rapid‑change chamber, temperature‑and‑humidity rapid‑change chamber, and sand‑and‑dust chamber. In the broader testing‑equipment market, such chambers are typically built from stainless‑steel or anodised aluminium frames, with internal temperature ranges from - 70 °C to +200 °C and humidity control from 5 % to 95 % RH. Vibration units often meet IEC 60068‑2‑6 specifications, offering frequencies of 5 Hz to 200 Hz and acceleration up to 20 g. Rain and sand‑dust chambers are designed to comply with IEC 60068‑2‑78 and MIL‑STD‑810, providing calibrated water spray or particulate flow rates. Typical grading includes ISO‑9001 quality management, CE marking for EU markets, and UL certification for North America, although buyers should verify each certification with the supplier.

Trade and Export Information - Doaho Test Company Co., Ltd.

China is a major exporter of environmental test equipment, and Chinese manufacturers regularly ship chambers to Europe, North America, and Southeast Asia. The HS‑code 8479 covers “machines and mechanical appliances having individual functions, not specified elsewhere,” which includes the test chambers listed by Doaho. Buyers commonly require CE conformity for EU entry, UL listing for the United States, and RoHS compliance for electronic components inside the chambers. Export packaging usually involves insulated wooden crates, with one reach‑in unit fitting a 40‑ft container and benchtop units stacking up to 20 units per 20‑ft container. Standard Incoterms employed are FOB Shanghai or CIF destination port, and customs documentation typically includes a commercial invoice, packing list, and certificate of origin.

Sourcing from Doaho Test Company Co., Ltd. - Buyer Guidance

When sourcing these chambers, request the latest product data sheet that details temperature, humidity, vibration, and pressure specifications. Ask for test reports demonstrating compliance with IEC 60068 series and any applicable MIL‑STD‑810 tests, as well as a copy of the CE Declaration of Conformity or UL listing. Verify the material of the chamber interior (e.g., 304 L stainless steel) and the control system brand to ensure compatibility with existing lab infrastructure. Most suppliers set a minimum order of one unit, with lead times ranging from six to eight weeks for standard models; customized temperature ranges or control software can extend the lead time. Confirm packaging dimensions, crate weight, and whether the unit is pre‑calibrated before shipment.
