Changzhou Jingwei Meters Electric Co. Ltd — Supplier
About Changzhou Jingwei Meters Electric Co. Ltd - Industrial Thermometer Supplier in China
Changzhou Jingwei Meters Electric Co. Ltd is based in Changzhou, China and currently lists five active products. The catalogue includes a Type A v‑shaped industrial glass thermometer, a Type B v‑shaped industrial glass thermometer, a round glass thermometer equipped with a protective case, a 9‑inch industrial adjustable‑angle glass thermometer, and diesel‑exhaust pyrometers. Each item is described by its physical form and intended industrial application rather than by performance specifications in the supplied data. The supplier is classified as an imported tier with a harbor trust tier, indicating it operates through third‑party logistics channels for cross‑border shipments. The product set targets users who require direct‑reading temperature measurement in manufacturing, processing, and emissions monitoring environments.
The listed thermometers belong to the instrument category covered by HS Chapter 90, specifically the sub‑heading for glass thermometers used in industrial settings. Diesel‑exhaust pyrometers are classified under the pyrometer sub‑heading of the same chapter, reflecting their function as non‑contact temperature measurement devices. No additional product attributes such as material composition or calibration status are supplied, so buyers must request those details separately. The catalogue does not reference any proprietary certifications held by the supplier.
Product Range and Specialties of Changzhou Jingwei Meters Electric Co. Ltd
The catalogue offers two v‑shaped glass thermometers (Type A and Type B) that are typically used for point‑temperature monitoring in process lines, with common industry grades ranging from - 40 °C to 350 °C and an accuracy of ±1 °C for standard models. Round glass thermometers with protective cases are often supplied in borosilicate glass, providing resistance to thermal shock and chemical exposure, and are frequently packaged in insulated boxes for safe transport. Adjustable‑angle glass thermometers of 9 inches are designed for mounting on irregular surfaces and usually feature a calibrated scale calibrated to IEC 60784‑1 standards. Diesel‑exhaust pyrometers are non‑contact infrared devices that commonly cover temperature ranges up to 1 200 °C, with response times under 2 seconds and emissivity adjustments for accurate exhaust gas measurement. Typical industrial thermometers are supplied with calibration certificates traceable to national standards, and buyers often request specifications such as glass type, scale division, and maximum temperature rating.
Trade and Export Information - Changzhou Jingwei Meters Electric Co. Ltd
China is a major exporter of industrial measurement instruments, and thermometers and pyrometers from the region are regularly shipped to buyers in Southeast Asia, Europe, and North America. HS 9025.20 covers glass thermometers, while HS 9025.80 includes pyrometers; shipments are usually packed in wooden crates or reinforced cardboard boxes to protect the fragile glass elements during sea freight, often under CIF or FOB terms. Importing countries frequently require conformity to IEC 60784‑1 for glass thermometers and IEC 60784‑2 for pyrometers, and buyers may request CE marking or ISO 9001 quality‑management certification from the supplier. Chinese manufacturers of these instruments commonly employ automated glass‑blowing and annealing processes to achieve consistent scale calibration, and bulk orders are typically loaded into 20‑ft or 40‑ft containers with a gross weight of up to 22 t per container.
Sourcing from Changzhou Jingwei Meters Electric Co. Ltd - Buyer Guidance
Potential buyers should request a recent calibration certificate for each thermometer model, specifying the reference standard, calibration date, and measurement uncertainty. For the diesel‑exhaust pyrometers, an emissivity calibration report and response‑time test results are standard documents that help verify performance against IEC 60784‑2. It is advisable to obtain a material safety data sheet (MSDS) for the glass components to confirm the use of borosilicate or similar high‑temperature glass, and to ask for a test report indicating compliance with any applicable CE or ISO standards. Verification of packaging dimensions, container loading plan, and the supplier’s export documentation (commercial invoice, packing list, and certificate of origin) will reduce customs delays.
Frequently Asked Questions About Changzhou Jingwei Meters Electric Co. Ltd
What temperature ranges are covered by the glass thermometers listed by Changzhou Jingwei?
The catalogue does not specify ranges, but industrial glass thermometers of this type typically cover - 40 °C to 350 °C, with accuracy around ±1 °C for standard grades.
Do the thermometers include calibration certificates?
Calibration certificates are not listed in the facts; buyers should request a current certificate that cites the reference standard and measurement uncertainty before placing an order.
What material is used for the glass in the round thermometer with protective case?
The material is not stated; however, most industrial glass thermometers are made from borosilicate glass, which provides thermal shock resistance and chemical durability.
Which HS codes apply to the diesel‑exhaust pyrometers?
Diesel‑exhaust pyrometers fall under HS 9025.80, the sub‑heading for pyrometers and other temperature‑measuring instruments without a contact probe.
What certifications should a buyer request for these instruments?
Buyers usually ask for IEC 60784‑1 compliance for glass thermometers and IEC 60784‑2 for pyrometers, along with any CE marking or ISO 9001 quality‑management certification the supplier can provide.
How are the thermometers typically packaged for export?
They are commonly packed in insulated cardboard boxes or wooden crates with cushioning material to protect the glass during sea or air freight.
What are typical lead times for these products from China?
Lead times vary, but industrial glass thermometers and pyrometers are often produced and ready for shipment within 4 to 6 weeks after order confirmation, depending on order size and required testing.
What container sizes are used for shipping the full product range?
Full shipments are usually consolidated into 20‑ft or 40‑ft containers, with a maximum gross weight of about 22 tonnes per container, allowing multiple units of each thermometer model and pyrometers to be loaded safely.
