从China供应商批量进口9" Industrial Adjustable Angle Glass Thermometer

The 9" industrial adjustable angle glass thermometer from Changzhou Jingwei Meters Electric Co. Ltd is a direct-reading temperature instrument built for industrial process monitoring where visual clarity and mechanical durability matter. The 9-inch (approximately 230 mm) glass stem provides extended reach into pipe wells, tanks, and ductwork, while the adjustable angle head permits the dial face to be oriented toward the operator regardless of mounting position. The thermometer uses a liquid-filled glass sensing element, standard for this class of instrument, with the liquid column responding to thermal expansion to indicate temperature against a calibrated scale.

The glass lens is tempered for resistance to thermal shock and mechanical impact in factory environments, though the housing material and exact IP rating should be confirmed with the supplier for outdoor or washdown applications. Typical industrial glass thermometers of this style employ a bimetallic or liquid-in-glass sensing mechanism; the adjustable angle fitting is usually brass or stainless steel with a compression seal to prevent leakage around the stem. Standard connection sizes for such instruments are 1/2" NPT or BSP, though Changzhou Jingwei Meters Electric's exact thread form and wetted materials require direct verification. Accuracy classes for general industrial glass thermometers typically fall within ±1% of span or ±2% of span per ASME B40.200, depending on grade.

Buyers in pharmaceuticals, food processing, and chemical manufacturing use this instrument for local temperature indication where electronic sensors are unnecessary or where a visual backup is mandated by procedure. The adjustable head suits installations in cramped boiler rooms, reactor skids, and HVAC plenums where fixed-angle instruments would require impractical viewing arrangements. When sourcing from Changzhou Jingwei Meters Electric Co. Ltd, confirm the temperature range, scale divisions, and whether the unit is mercury-free (now standard in most export markets). The supplier's imported tier and harbor trust tier indicate a verified business entity, though buyers should note the 0.00% response rate and zero average response hours, which suggests limited communication history on this channel.

Changzhou Jingwei Meters Electric Co. Ltd is located at 2# Ziyun Road, Changzhou 213021, China, placing it within the Changzhou instrumentation cluster in Jiangsu Province. The supplier carries an imported tier classification and a harbor trust tier, which indicates a baseline verification of business existence rather than an extensive track record of trade performance. The response rate of 0.00% and average response hours of zero are conspicuous gaps; these metrics suggest the supplier has not engaged inbound enquiries through this channel, or that the account is newly listed. Buyers should treat this as a signal to conduct independent due diligence rather than a disqualification.

The supplier's profile does not state factory size, year of establishment, annual revenue, export markets served, or named clients. No headcount, production capacity, or in-house calibration capability is mentioned. The listing description references ISO and CE certification, but no certificate numbers, accreditation bodies, or scope of certification are provided. A buyer should request the supplier's business licence, quality system certificate, and any product-specific test reports before placing a trial order. The address in Changzhou, a city with established thermometer and instrumentation manufacturing, provides plausible industrial context, but this alone does not substitute for verified credentials.
