Key Points of the Product

Built for the Shop Floor, not the Lab Bench.

Provide a Quick Check for your Spec.

Every impact is captured as Leeb hardness, then converted on-screen to HV, HB, HRC, HRB, Shore, or tensile strength — whichever scale your drawing calls out. Set GO/NG limits once and let the color-coded display do the QC judgment for you.

More Measurements. More Confidence:

A single reading only tells part of the story. Capture multiple measurements and use built-in statistical analysis to confirm consistency, identify variation, and make decisions with confidence.

Ten Materials, One Device.

From iron and gray cast to brass, and copper-tin alloys, select from the built-in material table (A‑1 through B‑4), and the HH‑V400 compensates automatically. No separate probes or lookup charts required in the field.

The Test Sequence

Four Steps. No Setup.

1. Turn it on

With a single power button, the display wakes straight into the material table.

2. Select the Material

Scroll to the sample material: iron, and steel, stainless, cast alloys, and more.

3. Press the Button

Hold the detector firmly against the surface and trigger the impact hammer.

4. Read the Result

Hardness appears instantly, with GO/NG judgment and running statistics.

Larger 2.8-inch Touchscreen

The bright, high-contrast display ensures clear visibility in various lighting conditions, while touch, swipe, and flick functionality streamline operation for quick measurement setup and data review, even when wearing gloves. For added convenience, the touchscreen can be disabled when needed, allowing for operation via physical buttons.

New HOME Key

The new HOME Key enhances user efficiency by providing one-touch access to essential functions and frequently used calibration and measurement conditions. This streamlined operation reduces setup time, improves workflow, and ensures a more intuitive user experience, especially in fast-paced manufacturing environments.

Compatible with new standard ISO 21920

The Mitutoyo SJ-220 is fully compatible with the latest ISO 21920 standard, ensuring its measurements align with the most up-to-date global surface roughness evaluation criteria. By supporting this standard, the SJ-220 provides greater consistency, traceability, and compliance for industries requiring the highest levels of quality control.

Increased Efficiency

The SJ-220 now has the ability to transmit measurement data wirelessly and display results and setting conditions with the optional U-WAVE-TIB. By attaching the optional wireless communication unit, it is possible to have wireless communication via Bluetooth® with a device (PC or smartphone) on which the dedicated app* is installed.
