Insize 9501-1200 Coating Thickness Gauge
Versatile coating thickness gauge for both ferrous and non-ferrous substrates. Resolution from 0.1 µm, 500-reading memory, USB output and software for data logging — well-suited to galvanising QC, automotive paint inspection and corrosion mapping.
Insize ISR-CS130-W Surface Roughness Specimen Set
30-piece pure-nickel surface roughness specimen set covering flat lapping, plain grinding, reaming, turning, and horizontal & vertical milling — Rz from 0.05 to 12.5 µm. Used to identify and visually compare machined-surface finishes by symbol.
Portable Hardness Testers — Leeb & Rockwell on the Workpiece
Portable hardness testers let you bring metrology to the part rather than the part to the lab. Leeb (rebound) testers like the Insize HDT-CB320 and Yamayo MHT-600 use an impact body that bounces off the workpiece — the ratio of impact-to-rebound velocity translates directly into hardness (HL), which the instrument then converts into the user's preferred scale (HRC, HRB, HV, HB, HS). They're ideal for large castings, forgings, weld seams, and structural steel where bench testing is impossible. Portable Rockwell testers like the Insize ISHR-P151 apply a known load and measure indentation depth directly — closer in principle to a bench Rockwell machine and used where direct ISO 6508 / ASTM E18 traceability is needed.
Coating Thickness Gauges — Magnetic Induction & Eddy Current
Coating thickness gauges measure the thickness of paint, zinc plating, anodising, powder coat or insulating film without damaging the substrate. The two principles — magnetic induction for non-magnetic coatings on ferrous metals (steel, iron) and eddy current for insulating coatings on non-ferrous conductive metals (aluminium, copper) — are now combined into a single auto-detect probe in modern dual-mode gauges like the Laserliner CoatingTest-Master, Yamayo TH-250 and Insize 9501-1200. They underpin paint shop QC, marine corrosion surveys, structural-steel galvanising inspection and automotive refinish acceptance, with traceability to ISO 2178, ISO 2360 and ASTM B499.
Surface Roughness Testers & Specimen Sets — Ra, Rz, Rq
Surface texture controls how a part performs in service — from sealing surfaces and bearing fits to fatigue resistance on rotating shafts. The Mitutoyo Surftest SJ-210 (178-563-01A) draws a fine stylus across the work and computes Ra, Rz, Rq and a full set of surface parameters per ISO 4287 / 16859, JIS and ANSI. For first-line shop-floor checks where a stylus instrument isn't justified, the Insize ISR-CS130-W 30-piece comparator set lets operators visually identify a finish symbol against pure-nickel reference surfaces machined by lapping, grinding, reaming, turning and milling. The two together — the Surftest for inspection and the comparator for quick verification — build a complete surface quality QC stack.
Calibration Certificates & ISO/ASTM Traceability
Every NDT instrument from SAN Tools can be supplied with a traceable calibration certificate referenced to national measurement standards — essential for ISO 9001, IATF 16949, AS9100, ASME and oil & gas inspection audits. We can issue certificates at point of sale or arrange recalibration on existing instruments through accredited UAE partners.

Frequently Asked Questions
Common questions about NDT instruments and ordering from SAN Tools.
What is NDT (Non-Destructive Testing) and what instruments do I need?
NDT covers any inspection or measurement that doesn't damage or alter the workpiece. The most commonly used handheld NDT instruments in fabrication, automotive and oil & gas are: portable hardness testers (Leeb or Rockwell) for verifying material spec and heat-treat quality; coating thickness gauges for paint, zinc, anodising and powder-coat QC; and surface roughness testers for verifying machined finishes against design tolerance.
What is the difference between Leeb and Rockwell portable hardness testers?
A Leeb tester (HDT-CB320, MHT-600) measures rebound velocity from an impact body and converts to hardness via lookup tables — very portable, fast, ideal for large or in-situ parts. A portable Rockwell tester (ISHR-P151) applies a known indenter load and reads indentation depth directly — closer in principle to a benchtop Rockwell machine, with more direct ISO 6508 / ASTM E18 traceability. Pick Leeb for speed and accessibility; pick Rockwell for direct scale conformity.
How does a coating thickness gauge work?
Modern dual-mode gauges (Laserliner CoatingTest-Master, Yamayo TH-250, Insize 9501-1200) auto-detect the substrate and switch between two principles: magnetic induction for non-magnetic coatings on ferrous metals (paint or zinc on steel), and eddy current for insulating coatings on non-ferrous conductive metals (anodising on aluminium). The gauge places its probe on the coated surface and reads the coating thickness in microns within a second.
What surface roughness parameters should I measure — Ra, Rz, Rq?
Ra (arithmetic mean roughness) is the most commonly specified parameter and the default on machine-shop drawings. Rz (mean peak-to-valley height) is preferred for sealing surfaces and where peak height matters more than average roughness. Rq (RMS roughness) is statistically more sensitive to outliers and used in precision optics and bearing applications. The Mitutoyo SJ-210 reports all three plus the full Rk family of parameters per ISO 4287 / 16859.
Are calibration certificates available for these instruments?
Yes. We can supply traceable calibration certificates referenced to ISO 6508 / ASTM E18 (hardness), ISO 2178 / ISO 2360 (coating thickness) and ISO 4287 / 16859 (surface roughness) on request — either at point of sale or via accredited UAE calibration partners. Just message us before placing your order and tell us which audit standard you need to satisfy.
Can the Leeb hardness tester be used on small or thin parts?
Leeb testers have minimum mass and thickness requirements (typically >5 kg part mass and >25 mm wall thickness for a D-probe). For thinner or smaller parts, you can either couple the part to a heavier base, switch to a different impact device (C, DC), or move to a portable Rockwell tester (ISHR-P151) which uses a clamping fixture and has no minimum-mass requirement.
Do these coating thickness gauges work on plastic substrates?
No. Both magnetic-induction and eddy-current principles require a metallic substrate. For coatings on plastic or non-conductive bases you'd need an ultrasonic coating thickness gauge — we can source these on request, just message us with your application.
Is the Mitutoyo SJ-210 178-563-01A genuine Mitutoyo Japan?
Yes — SAN Tools is an authorised Mitutoyo distributor in the UAE. Every Surftest SJ-210 ships in original Mitutoyo Japan packaging with serial numbers, factory test report, retractable drive unit and full manufacturer warranty.
How portable are these NDT instruments — can I take them on site?
All eight products on this page are designed for handheld field use. The Leeb hardness testers fit in a pocket-sized case, the coating gauges run on AA batteries with USB data download, the Surftest SJ-210 has a built-in rechargeable battery, and the roughness specimen set ships in a hard carry case for site use.
What is the typical lead time?
Items shown above are usually in stock for same-day pickup at our Dubai branch and next-day delivery across the UAE. Special-order or accessory items (extra impact probes, replacement styli, calibration foils) typically arrive within 2–4 weeks from the manufacturer.
Do you supply impact probes, replacement styli and calibration foils?
Yes. We stock or can source the full accessory range — D / DC / C / G impact devices for Leeb testers, replacement styli for the SJ-210, calibration zero blocks, calibration foils for coating gauges, and consumables. Send us the part number on WhatsApp.
Where can I get my NDT instruments serviced or recalibrated in the UAE?
SAN Tools partners with accredited UAE calibration laboratories that service and recalibrate Insize, Yamayo, Mitutoyo and Laserliner instruments to ISO 17025 standards. Drop your instrument at any of our three branches (Dubai, Sharjah, Ajman) and we'll handle the recalibration, certification and return on your behalf.
