Questions Buyers Ask
Are you the manufacturer or a trading company?
Manufacturer. PRESS SPEC is the export brand of a Guangzhou pressure instrument factory. We machine, assemble, calibrate and test in our own facility, so pricing is factory-direct and custom ranges, threads and outputs are handled in-house — see our about page for the factory story.
What is your MOQ?
Standard models: 10 pieces. OEM / ODM programs with custom ranges, cable length, labels and packaging start at 100 pieces per model, and we can ship mixed-model containers for distributors. Samples are usually dispatched within 5–7 days.
Can you customize pressure range, output and thread?
Yes. Ranges from 0–0.1 MPa to 0–40 MPa (up to 0–60 MPa on the PT200 series), outputs 4–20 mA two-wire, 0–5 V, 0–10 V, RS485 Modbus or HART, and threads G1/4, 1/4NPT or M20×1.5 are all configurable at the factory.
What is your typical lead time?
Standard models: 7–15 days after order confirmation. Custom and OEM orders: 20–30 days depending on range and quantity.
Do you provide warranty and technical support?
Yes — 12 months warranty from shipment. Our engineers answer selection, wiring and troubleshooting questions by email and WhatsApp, and we offer remote technical support for integration issues.
