Hardness TestersBench-Top or Portable Hardness Tester: Which Workpiece Needs Which
Hardness testers split into two families before anything else. Choosing wrong has a direct cost: a bench unit cannot test an installed part, and a portable unit cannot produce arbitration-grade…
Hardness TestersHardness Scales Compared: Leeb, Brinell, Rockwell and Vickers
Hardness is not a single number. Different scales measure different things, and picking the wrong one makes the data incomparable.
Thickness GaugesMeasuring Steel Thickness Through a Coating in Three Steps
On a coated pipe you want the remaining wall, not a stripped section. Ultrasound offers a route: send the sound through the coating and reflect only from the metal.
Hardness TestersUsing a Portable Hardness Tester in Heat and Cold
The instrument does not fear temperature itself - it fears the drift temperature causes. Heat pushes circuit parameters off, cold kills batteries and displays. The two ends need different answers.
Roughness TestersHand-Held Roughness Tester: Three Prerequisites
A hand-held unit is treated as something you pick up and use. A number you can defend takes three things: a prepared surface, consistent parameters and a steady hand.
Hardness TestersFour Factors That Affect Leeb Hardness Accuracy
Two people, one test block, two different values. The instrument is usually fine. Leeb hardness is extremely sensitive to impact conditions - here is what decides whether the number is…
Hardness TestersLeeb Hardness Tester Faults: What You Can Fix and What Must Go Back
Leeb tester faults follow a clear pattern. What you can solve yourself is in the screen, the printer and the cable; anything involving circuitry or the impact mechanism goes back…
Flaw DetectorsSix Field Faults on Colour-Screen Flaw Detectors
A colour display makes the waveform clearer, and makes field problems more visible too. Display, drift and adaptation account for most failures.
Flaw DetectorsWhat a Colour Screen Actually Changes on a Flaw Detector
From monochrome to colour, the display has changed three times. It does not change the physics; it changes how fast you read a waveform, how sure you are, and whether…
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.
