Product features

ZK190 ultrasonic hardness is hardness calculation and measurement by means of ultrasonic vibration sensor to measure hardness. Its features is: destructive small, measurement speed fast, shows value precision high, both can determination ferrous metal, nonferrous metals and carbide artifacts of hardness, also can measurement non-metallic artifacts of hardness, special for on metal thin layer (including infiltration nitrogen, carburizing, plating layer,), metal sheet, easily mobile of large artifacts, easily demolition of parts, and bearing ball or gear surface, special shape of parts directly for percent of hardness test. Hardness measurement, the probe can measure vertically downward, can also be measured, looking up random direction of measurement, such as logging, capable of performing other types of hardness testing of difficult. Due to the small indentation, hardness and metallographic analysis, would raise a number of the analysis ability.

ZK190 ultrasonic hardness tester features: small size, light weight, easy to carry, high reliability, and SCM intelligent, fully functional; High, medium, low block three-point calibration, greatly improving the precision of measurement.

Use method and adaptability of hardness test block

Handheld probe test specimens should be trying to make head and perpendicular to the surface of the specimen. When the head of diamond head when contact with the specimen surface, keep the measuring head perpendicular to the surface of the object at the same time, needed a smooth uniform strength makes the diamond Indenter is all pressure, protection Cap with the specimen surface contact, do not shake, after about two seconds the displayed measurement value of the hardness of the point value. Probe and sample hardness value, the longer exposure time is normal, because the longer the deeper the indentation, hardness values are lower.

Handheld probe methods, proficiency and experience is the key to ensure accurate measurement, the training and experience to be repeated. Who who will use the calibration instrument the best instrument.

Specimen surface, evenness and penetrating

General specimen surface roughness of less than 1.2 μ m, can a test be accurate readings. For specimens such as rough casting surface, through a grinding Dresser, if not clean, you can get a set of average of the readings to obtain more accurate measurements, if the organization is not very uniform throughout the surface of the specimen, may, where appropriate, to measure points, taking its entire surface is obtained as the average hardness readings.

12N loads, Rockwell indentation depth is 4 C20-70 steel specimen about µ m-50 µ m, from which to determine the degree of adaptation to the hardness measurements on the surface of the specimen.

When the sheet metal or hard material when measuring the cavity part, it is important to make it more than the penetration depth of the Indenter, provisions of the rough, the thickness of the test piece at least head penetration depth more than 10 times, achieved when reading is incorrect. When measuring the sheet metal, sheet metal with high quality metal surface on the back pad.

Instruments by 'HRC', ' HB', ' HV' key to change the hardness scale. Each a hardness scale for the calibration of hardness scales.

Equipment maintenance

Total power consumption of the instrument approximately 55mA (printer). When the battery voltage is too low, the LCD display will become (LB is ' battery undervoltage ' English Low battery), then recharge it. Charger red light in a charged state, when charging is complete the red light turns green and automatically stops charging. AC powered device charger can also be used as instruments. Rechargeable battery for 5 1.2V Ni-MH batteries, it can be replaced. Instrument without also regularly check for a long time, boot if the show, will be charged.

Equipment to be stored in a dry, clean place, the ambient temperature should be 40 deg.

Probe fell to absolutely avoid to touch.
