Where Wenzhou sits in instruments & metering
Wenzhou is a secondary cluster rather than the biggest one. It holds 5% of the instruments & metering suppliers in our directory, so buyers normally price this city against two or three larger clusters before committing — the quotes are often keener for that reason.

| Hangzhou | 19 | 7% |
| Wenzhou | 15 | 5% |
| Shanghai | 14 | 5% |
| Shenzhen | 13 | 4% |

Before you request a quote
Instrument makers cluster in Jiangsu, Zhejiang and Guangdong. Calibration certificates and the accuracy class at temperature extremes are what buyers actually audit.
What to put in the RFQ
Most price gaps between Wenzhou suppliers come from the brief, not from the factory. Include these and the comparison gets honest:
- Drawing or spec sheet, with tolerances and the critical dimensions marked.
- Material grade and any substitution you would accept.
- Surface finish, colour reference and packaging method.
- Sample quantity, trial order quantity and expected annual volume.
- Certification the product must carry, and who pays for the testing.
- Trade term and destination port, so freight is priced the same way.
- Required delivery date, plus how much slip you can absorb.
- Inspection method: who inspects, at what stage, and against which standard.
How to check a supplier before you pay a deposit
Company names in a directory tell you who exists; they do not tell you who can actually run your order. In Wenzhou the checks that catch most problems are the boring ones: the business licence name matches the factory address on the contract, a live video walk-through shows the machines the process needs rather than a showroom, and the test report is issued for the material you specified rather than a generic certificate. Put the inspection stage, the acceptance standard and the payment split into the contract — a 30/70 split against a pre-shipment inspection is normal, full payment up front is not.
