Demeq QH7 Portable Hardness Tester

Demeq QH7 Portable Hardness Tester

Heavy Duty Portable Combination Hardness Tester for Leeb and UCI Testing Methods

Heavy Duty Combination Leeb and UCI Hardness Tester

The all new Demeq QH7 Series hardness testers operate on the Leeb and or UCI methods of hardness testing depending on the model. This allows for solutions in most metal hardness testing applications with robust instruments that are ideal for use in heavy industry applications including mining.

These instruments are both modular and upgradeable, at a fraction of the price of competitors' hardness testers.

Features:

  • Complies with ASTM A-956 & ASTM E-140 standards
  • Measure in any direction with auto angle detection
  • CalTag technology on impact devices and probes
  • Graphical representations and statistics
  • Rechargeable batteries
  • Aluminum enclosure with rubber sides
  • DMQ DataCenter software with Bluetooth data transfer and programmable quick access keys
  • Color backlit alphanumeric LCD display
  • 5-Year limited warranty

 

DMQ DataCenter Software

DataCenter is software used to transfer and process data stored in the unit memory. With the tools in DataCenter you can generate statistics, graphics, export data to other programs and prepare custom reports. With the QH7, measurements can be transferred using a USB cable or by Bluetooth.

Leeb Type Impact Devices & UCI Probes

Leeb Type Impact Devices

Model # Probe Type Application
QHS102 Type D Standard impact device for most hardness testing tasks
QHS201 Type DC Extremely short impact device for measurements at difficult-to-access locations such as holes, cylinders, internal measurements
QHS301 Type DL Impact device with extended impact body for measurements in confined spaces
QHS501 Type C Impact device with reduced impact energy for measurements on surface-hardened/case-hardened materials, superficial hardness and thin samples
QHS601 Type G Impact device with increased impact energy for measurements on rough surface finishes, heavy castings and forged parts. The surface quality requirements are lower as with type D. Brinell only.
QHS701 Type E Probe with indenter made of polycrystalline of boron nitride intended for control of materials with high hardness
UCI Probes

Model # Probe Type Application
QHS110 1 kg (10N) For plated parts and those with surface treatments (electroplated coating - chrome, copper, nickel, zinc, tin), case hardened materials, and thin walled and small-sized items
QHS150 5 kg (50N) For hard material – Rockwell C, ground surface, and fine grain, like gears, cam shafts, etc. shop inspection 
QHS198 10 kg (98N) For softer materials - Brinell and Rockwell B scale, with slightly rougher and coarser grains – pipe, weldments, field testing

*Impact devices and UCI probes for QH7 Series hardness testers include CalTag technology so that instruments recognize the impact device or probe being connected so that no adjustments need to be made to the unit. GyroTag is added for auto impact angle detection.
