FAQ

Q1: Can you produce this sensor probe shaft according to my custom drawing?

A1: Yes. We accept fully custom manufacturing based on your 2D drawings, 3D CAD files or physical samples. Our engineering team will perform DFM review and provide feedback before production.

Q2: What stainless steel grades are available for this temperature probe?

A2: 304 stainless steel is the standard option for general industrial environments. 316L stainless steel is recommended for corrosive media, high humidity or chemical industry applications.

Q3: What is the minimum order quantity?

A3: We support prototype small batch and mass production orders. MOQ is flexible, we can start from 1 piece for sample testing.

Q4: Can you do surface passivation for anti-corrosion?

A4: Sure. Passivation treatment can be added to remove surface free iron and enhance corrosion resistance, suitable for long-term temperature measurement in wet or slightly corrosive surroundings.

Q5: How do you guarantee the precision of the tapered probe and thread?

A5: All parts are processed on CNC turn-mill machines. After machining, we use thread gauges, micrometers and CMM to inspect critical dimensions including thread accuracy, taper and concentricity.
