Metal Hardness Tester HL30

This light-weight portable hardness tester has a user-friendly membrane. Hardness scale, material, average time and some other functions can be set through short-cut keys. It has upper/lower limits setting and alarm. Holder in the back holds the unit up to free engineer's hands.

Features: Measuring accuracy Repeatability Impact direction Hardness measurement value Measuring range Onboard memory Optional impact device Charging time Continuous working hours Communication interface Operating temperature Dimensions Weight Backlight Features of External Impact Devices: D probe is for standard use. DC probe is short and is convenient in small space. ±6 HLD of reading at HLD=760 6 HLD of reading at HLD=760 0º, ±45º, ±90º HL, HRC, HRB, HB, HV, HSD HRC 20.0 ­ 68.0 600 data D, DC, DL, D+15, C, G 2-3.5 hours Approx. 200 hours(without back light) USB 0°C-45°C 152×84×34mm 9 oz (with probe D)

DL type is used in confined surfaces such as gear wheels. D+15 type is for measuring in grooves or recessed surfaces. C type is used on surface-hardened, coated, thin-walled or impact sensitive components. G type is used on heavy and rough cast and forged work pieces.
