QH2 Portable Hardness Tester 


QH25 year warranty

Use a QH2 portable hardness tester to easily measure hardness in steel, cast steel, alloy tool steel and stainless steel. 

The QH2 hardness testers are supplied with a type D impact device a printed quick users guide, high impact carrying case and USB cable to transfer data saved in the unit memory to a PC using DMQ DataCenter software (included).

QH5 Leeb Metal Hardness Tester 

 QH5 

The QH5 Leeb or Rebound Metal Hardness Testers are easy-to-use portable instruments that offer quick and accurate hardness measurements in the most common hardness units such as Brinell, Rockwell, Vickers and more. Take the QH5 with you and test large or heavy parts on-site, check incoming parts, identify and classify parts in stock, measure in areas with limited access and conduct tests during production. 

Three models to choose from :

DMQ  model D or DC 

Connect a DMQ type D or DC impact device and measure the widest range of metals, hardness units, and hardness ranges covered in the Leeb method. 
All QH5 models feature histogram graphics, real time statistics, selectable viewing modes, a Data Logger to store 32000 readings that can be sent to a PC and much more.

DMQ Model G

Connect a DMQ type G impact device to the QH5 and measure hardness in massive, founded and or forged parts with rough surface finishes. In Brinell measure up to 650 HB.
All QH5 models feature histogram graphics, real time statistics, selectable viewing modes, a Data Logger to store 32000 readings that can be sent to a PC and much more.

DMQ Model M 

 Connect a DMQ type G impact device to the QH5 and measure hardness in massive, founded and or forged parts with rough surface finishes. In Brinell measure up to 650 HB. 
All QH5 models feature histogram graphics, real time statistics, selectable viewing modes, a Data Logger to store 32000 readings that can be sent to a PC and much more.

QH5 U Leeb Metal Hardness Tester 

 QH5 U

The QH 5U model is a portable metal hardness tester that operates on the UCI or Ultrasonic Contact Impedance method. It is factory calibrated for steel allowing for precise measurements in thin and light weight parts as well as in large parts leaving an indentation that is practically invisible. 

The native hardness unit for the QH5 U is HV (Vickers) with immediate conversions according to ASTM E140 standards to other hardness units such HB (Brinell), HRB (Rockwell B), HRC (Rockwell C) and HS (Shore).

All QH5 Series models include a Datalogger to store up to 32000 measurements that can be sent to a PC via USB using DMQ DataCenter software available at no extra charge.

QH7 Metal Hardness Tester 

The QH7 Series HEAVY-DUTY Portable Hardness Testers are presented in a rugged extruded aluminum enclosure designed to support operation in the most adverse conditions. QH7 hardness testers operate on the Leeb and UCI methods and are used to measure the hardness of all metals and metal alloys with hardness values expressed in common hardness units such as Vickers (HV), Brinell (HB), Rockwell (HRB & HRC) and Shore (HS).

Three models to choose from : 

QH7 L Metal Hardness Tester 

 QH7 LEEB

The QH7 HEAVY-DUTY Leeb hardness testers use DMQ impact devices with CalTag technology so that you don't have to calibrate the unit when changing devices and GyroTag technology so that the impact angle is automatically recognized.

QH7 U (UCI) 

QH7 UCI

The QH7 U is a HEAVY-DUTY UCI hardness tester that is factory pre-calibrated for steel while for other metals you can calibrate in very simple steps using reference blocks of the same material.

QH7 C Combined Leeb and UCI 

QH7 LEEB UCI

The QH7 C is the most complete and advanced HEAVY-DUTY portable metal hardness tester available from Demeq because it combines the Leeb or rebound method and the ultrasonic contact impedance (UCI) method which compliment one another allowing coverage on the widest range of portable metal hardness testing applications. 

Impact devices as well as UCI probes include CalTag technology so that the unit automatically recognizes the device or probe being connected so there is no need for adjustments or calibration.
