AI-Powered supplier vetting

SummaryChongqing Hongxing Instrument Co., Ltd. is identified as a China-based manufacturer/factory in the industrial instruments and meters sector, although another slice classifies the company nature as a trading company. Its product scope includes pressure, flow, differential-pressure, electromagnetic, and multi-parameter instrumentation. The supplier states that it holds ISO 9001 certification, has 6–10 years of R&D engineer experience, 11–20 quality-control staff, and operates two production lines. It reports export activity beginning in 2023, exports through agents among other methods, and serves markets across multiple regions. Stated lead times are within 15 working days in both peak and off-peak seasons. Evidence supports manufacturing, quality-system certification, R&D, production, and international sales capabilities. However, the provided information does not sufficiently establish after-sales performance, financial credibility, customization execution, or specific customer cases.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory in China and operates in Instruments & Meters, while a separate record describes its company nature as a trading company. The available records therefore indicate manufacturing capability but also contain a classification inconsistency.

CertificationsThe supplier explicitly reports certification of its management systems under ISO 9001. This provides direct evidence of holding a recognized quality management certification.

R&D capabilityThe supplier states that it conducts instrument R&D, adheres to independent research and development, and has 6–10 years of total R&D engineer experience. These statements and staffing data directly support an established innovation function, although no specific patents, new-product records, or technical achievements are supplied.

Production capacityThe supplier describes itself as engaged in instrument production, is classified as a Manufacturer/Factory, operates two production lines, and reports lead times within 15 working days in both peak and off-peak seasons. These data support active production capability and stated delivery capacity.

Product Q&A

Q:What is the working principle of this transmitter?

It measures and calculates mass flow as a function of differential pressure (DP), absolute pressure, and temperature for fully compensated measurements.

Q:What output signals are supported?

The device supports 4-20mA analog output and RS485 communication (Modbus-RTU 4-wire system).

Q:What is the accuracy and range ratio?

The accuracy grade is 0.25, with available range ratios of 1:200, 1:400, or 1:500.

Q:Can it be powered by a battery?

Yes, it can be optionally powered by a battery, which works for 2-3 years without external power supply.

Q:What certifications does the product have?

The product has ISO certification and ExdllCT6GB explosion-proof certification.
