HRS-150 Digital Automatic Rockwell Hardness Tester

Product Description

The HRS-150 Digital Automatic Rockwell Hardness Tester integrates optical sensing, computer control, and electronic data processing for high-precision hardness measurement.
It adopts an automatic loading, dwell, and unloading system, completely eliminating operator errors.
Hardness values are displayed directly on the LCD screen with a resolution of 0.1 HR, and automatic unit conversion between HR, HB, and HV is supported.
The built-in printer allows quick output of measurement results, while the RS-232 interface provides easy data transfer to external devices.
Its cast aluminum body, made by one-piece sand casting, guarantees long-term mechanical stability.
The automotive-grade enamel coating provides superior scratch and corrosion resistance.
Fully compliant with ASTM E18, ISO 6508, and EN 10109 international standards, this instrument is ideal for industrial quality inspection and laboratory testing.
