The ET3 (Equotip-3) is Proceq's flagship hardness testing unit built to include all the features needed for in-depth analysis of the material properties that influence hardness.
Depending on the application, additional impactors can be equipped to tailor the ET3 to best suit the test material.
Features include:

• Good for all metal types
• Shock resistant ABS plastic design
• Automatic compensation for impact direction and surface curvature
• Intuitive software which can be used to upload results to a PC
• A range of units to select from
• Standard accuracy of +/- 4HL
• Uses dynamic testing principle - Superior to rebound technique
• Optional impactors - An extensive range of impactors to tailor inspections
• Can be supplied with test blocks and supports

For information on the optional impactors available and their specifications please see the pdf file below or contact our technical sales department at our main branch in Sheffield.

Johnson and Allen supply Proceq's EQ1000-B2 (Proceq Bambino) and EQ1000-P2 (Proceq Piccolo) portable pen type hardness testers. These instruments are ideal for quick verification of material hardness.

For customers requiring hardness results from components under 5kg and with sections thinner than 3mm please see the ES3 hardness tester instead.

EQ1000-B2:

• Pen design - Easy to use and ideal for quick measurements in the field
• Uses the Leeb impact rebound method
• A range of commonly used scales are selectable
• Suitable for a large range of metals
• Large display - Easy to read in dusty or dark environments
• Supplied with D impact device - Optional DL impact device for working in confined spaces
• Minimum thickness uncoupled/coupled of 25mm/3mm
• Indicator 24 month warranty, mechanical and electro-mechanical 6 month warranty
• Test blocks and support rings available

EQ1000-P2:

• All the features found in the EQ1000-B2
• Real-time monitoring of hardness
• Automatic testing during serial production
• Extra software functions to evaluate and process results
• Remote control testing possible

The ES3 (Equostat 3) is a hardness tester designed with thin and small test objects in mind. Hardness test results are negatively affected by thin and small volume materials unless they are compensated for. The ES3 achieves this by using Proceq's patented and pre-installed software package in conjunction with specially designed impactors to account for this.
The ES3 is supplied with a freehand measuring unit as standard but a clamp unit for thin sections is also available - Hardness measurements can be made on material sections as thin as 1mm.
