Roughness Testers

Pocket Roughness Tester: What a Small Body Can and Cannot Do

A pocket unit fits in a palm, and pays for it in range, probe and stability. Knowing which jobs it covers is more useful than reading the spec sheet.

Roughness Tester Care and the Six Faults You Will Actually Meet

What fails most on a roughness tester is not the electronics but the stylus and the connectors. Three habits cover the care; six categories cover the troubleshooting.

Ultrasonic Thickness Gauges: Four Tiers and What to Check Before Buying

The same category of instrument can differ fivefold in price. The difference is not the housing - it is velocity range, probe compatibility and signal processing.

Cleaning and Protecting a Thickness Probe: A Checklist

The part that fails most often on a thickness gauge is not the circuit, it is the probe. Once the face is scored or the connector oxidises, the reading drifts…

Seven Ways to Measure Coating Thickness, and Which Ones Damage the Part

Coating thickness is not just "touch it with a probe". From cross-sectioning to X-ray fluorescence there are more than seven methods, and picking the wrong one costs more than picking…

超声波测厚读数不准的 13 个原因,按排查顺序排列 — 测厚仪Thickness Gauges

13 Reasons Ultrasonic Thickness Readings Go Wrong, in Checking Order

Same gauge, same batch of parts, numbers that do not match. Most problems come from coupling, velocity and surface condition. Here they are in the order you should check them.

Hardness Testers

What a Portable Hardness Tester Can and Cannot Measure

A portable hardness tester is often treated as a tool that hits anything. In practice it has four hard requirements, and missing any of them makes the number meaningless.

油漆涂层测厚仪:磁性法与涡流法的分工 — 测厚仪Thickness Gauges

Magnetic or Eddy Current? Choosing a Coating Thickness Gauge

Two physical principles, two substrate families. Pick by what the coating sits on, not by price or by which one the salesman has in stock.

超声波测厚仪怎么算出壁厚:一个公式背后的四道工序 — 测厚仪Thickness Gauges

How an Ultrasonic Thickness Gauge Calculates Wall Thickness

h = v x t / 2 is the whole principle. What decides accuracy is how well those two variables are measured.

Тодорхой загварт тусламж хэрэгтэй юу?

Загварын дугаар болон асуудлын товч тайлбарыг илгээнэ үү — манай инженерүүд 8 цагийн дотор хариулна. Эсвэл аль ч хуудасны баруун доод булан дахь чат товчийг ашиглана уу.
