The short version · Three things to know before the datasheet
What it doesFor measurement and inspection of Hardness Testers, producing traceable records instead of visual checks and manual calculation.
Who it fitsIncoming inspection, lab sampling, process validation and final inspection — the larger the batch and the tighter the tolerance, the bigger the gain.
Not the right fit ifIf you only need a one-off rough check, or your parts exceed this model’s range — in both cases we will propose a cheaper route.

1. Your requirement
The goal is accurate, fast and traceable measurement. This proposal is built around those three: the machine secures accuracy, the accessories secure fixturing and throughput, the software secures traceability.
Taking the MH310 as an example, configuration in section 5; if sample size or batch differs from the description, fixtures and range are adjusted at the technical-protocol stage without changing the base model.
2. How the system is built
Measuring capabilityWhat it can measure — the first thing to check against your samples
Accuracy & resolutionError, repeatability and smallest reading — whether data can be used for acceptance
Loading & controlLoading mode, speed, dwell and software interfaces
Power & environmentPower, consumption and ambient requirements
Modules listed reflect this model’s actual configuration; an omitted group means it does not apply, not that it was left out.
3. Why this model
- Model and configuration follow the actual test object — no one-size-fits-all recommendation.
- Each model comes in a premium and a standard build, so budget and accuracy can be discussed separately.
- Factory installation, commissioning and training — producing reports from day one; automation or data interfaces can be added later without replacing the machine.
- A premium build of the same model is available: tighter assembly tolerances, upgraded components and higher-grade factory calibration, suited to metrology institutes and research acceptance.
Before you sign: what the price includes — and what it does not
This section is written before signing so that nothing turns up missing on delivery day. It follows the standard configuration; special requirements can be listed separately in the technical agreement.
Included
- Main unit plus factory standard accessories (see Section 5)
- Factory inspection report, certificate, packing list, operation and maintenance manual
- First installation, commissioning and operation training (remote or on site, travel included)
- One-year warranty on the whole unit; free upgrades within the same software version for life
- Domestic transport and transit insurance (up to unloading at your plant)
Not included (quoted separately)
- Special fixtures, custom tooling and modifications beyond the standard range
- Third-party metrology verification or calibration (if a CNAS certificate is required)
- On-site power modification, foundation, compressed air, temperature and humidity control
- Consumables (indenters, cutting wheels, polishing cloths, reference blocks)
- Out-of-warranty on-site service and spare parts

Three things to check before you compare
- The scale matters more than the number. If the drawing says HRC, measure HRC; if HV, measure Vickers. Converted values are for reference only.
- Range is not accuracy. Range tells you what fits; error and repeatability tell you how accurate it is — read both columns together.
- Acceptance is proven on your samples, not on the brochure. Provide 3–5 real workpieces for an on-site repeatability test; sign once the numbers match.
If you need a benchmark against your current or an imported instrument, we can run the same samples and issue the data.

5. Scope of supply
- Main unit, tool kit and manual
- Factory calibration certificate and conformity certificate
- Power cable and standard accessories
- First installation, commissioning and operator training
Consumables and spares are quoted separately by annual usage; for the first order we recommend one set of wear parts to avoid downtime.
6. Inspection workflow
01Sample prep: prepare specimens to the standard, record IDs and ambient conditions
02Fixturing and setup: select the program, confirm load, range and scale
03Measure and verify: consecutive measurements with out-of-tolerance alerts and re-test when needed
04Reporting: export data with calibration status and measurement uncertainty
7. Applicable standards
- GB/T 17394.1 Metallic materials — Leeb hardness test — Part 1: Test method
- JJG 747 Verification Regulation of Leeb Hardness Testers
- GB/T 230.1 Metallic materials — Rockwell hardness test — Part 1: Test method
- GB/T 231.1 Metallic materials — Brinell hardness test — Part 1: Test method
- GB/T 4340.1 Metallic materials — Vickers hardness test — Part 1: Test method
