Härteprüfgerät TIME®5350
Digital hand-held Leeb hardness tester

TIME®5350

The TIME®5350 is the top model of the TIME Leeb series and combines all functions in a particularly compact housing the size of a mobile phone. TIME built China's first Leeb hardness tester in 1989 and has been one of the leading manufacturers of hardness testing technology ever since.

The TIME®5350 can be used for virtually all hardness measurements on ferrous and non-ferrous metals with 7 selectable impact devices; the universal impact device type D is included in the scope of delivery. It is easy to transport and therefore the ideal tool for hardness testing directly on site.

The 3.5-inch colour display shows the following:

  • Measurement result
  • Bar chart graphic
  • Material / impact device type / impact direction
  • Maximum / minimum / average
  • Memory location / number of measurements / date and time

Up to 200 measurement groups are stored internally; in addition, the readings can be saved on a microSD card with up to 32 GB.

Features

  • compact hand-held instrument the size of a mobile phone
  • conversion of the common hardness scales (HL, HV, HB, HRC, HRB, HS) and conversion into tensile strength
  • 7 selectable impact devices with automatic identification; universal impact device type D included in the scope of delivery
  • 3.5-inch colour display with 320 × 480 pixels and three brightness levels
  • memory for 200 measurement groups including single value, average, date, impact direction, number of measurements, material and hardness scale
  • adjustable upper and lower limit values with audible alarm
  • data transfer to the PC via USB or RS232 in Word and Excel format; powerful PC software included
  • microSD card with up to 32 GB for storing the readings
  • detachable printer optional, readings can be printed directly
  • built-in conversion table; HB value directly readable with impact device D/DC
  • software calibration function

Applications

  • measurements on steel, cast steel, tool steel and stainless steel, grey and nodular cast iron, brass, bronze, wrought aluminium and copper alloys
  • measurements on large and small hollow shapes, bearings, heavy workpieces and permanently installed parts
  • failure analysis on pressure vessels, steam generators and their equipment
  • fast hardness testing directly on site

Additional equipment

  • additional impact devices for special applications (DC, D+15, C, G, DL)
  • support rings for measurements on curved surfaces with a radius of less than 30 mm
  • detachable printer for printing the readings directly

Application of Impact Devices
Impact Device DStandard impact device for most hardness testing tasks
Impact Device DCExtremely short, for measurements in holes, cylinders or internal measurements on workpieces
Impact Device DLDiameter of the tube in the front part: 2.78 mm;
for measurements in tight inaccessible places and recesses
Impact Device D+15Particularly narrow attachment with recessed coil for measurements in grooves and recesses,
same properties as Type D; only for steel
Impact Device CReduced impact energy, approx. 1/4 of Type D;
for surface-hardened workpieces, coatings, thinly coated or impact-sensitive parts (low impression depths)
Impact Device GEnlarged impact body with increased impact energy (approx. 9 times larger than Type D);
only small damage to the surface; only for measurements in the Brinell range;
for solid material, heavy castings and forgings
