934-1S digital Babbitt hardness tester
The Pasteur hardness tester (Barker hardness tester) is an indentation type hardness tester. Fast, simple and easy to test, it can be used to quickly test the hardness of aluminum and aluminum alloy materials, in accordance with American standards ASTM B648.. Test Method for Measuring Hard Plastic Indentation Hardness ASTM HD2583-07《 Pasteur Hardness Meter and Test Method for GB/T 3854-2005》Reinforced Plastic Barker Hardness.
1、 Purpose ：
Pasteur hardness tester is mainly used to test the hardness of aluminum and aluminum alloy, also can test the hardness of other soft metal and FRP products. Can test all kinds of super large, ultra wide, super thick workpiece and assembly parts, test sheet, strip, profile, forgings, castings, etc.
A W-20 type Wechsler hardness tester widely used in aluminum processing industry is suitable for most aluminum alloys. For 2024,7075 and other super hard aluminum alloy, you can use the W-B75 type Wechsler hardness meter, or pasteurian hardness meter. For pure aluminum, low hardness aluminum alloy, especially thick aluminum alloy and other aluminum alloy workpieces which are not convenient to use Wechsler hardness meter should use pasteurian hardness meter.
The pasteurian hardness tester is generally used as a supplement to the Wechsler hardness tester when testing pure aluminum, low hardness aluminum alloy and super large, super thick materials.
2、Advantages ：
* Equipped with bracket rotary positioning device。
* Machine automatic conversion of hardness HW、HV、HB、HRE、HRF、HRB、HRH
* With maximum value retention function, record the maximum hardness value during measurement.
* Has the average value calculation function, calculates the average value of up to 29 sets of data
* small size, light weight (550 g), easy to carry.
* Good stability, easy calibration and high detection accuracy
* One-handed operation, no use of experience, in any situation, as long as the reach can be tested.
* wide test range. From very soft pure aluminum to particularly hard aluminum alloys, the effective test range is equivalent to Brinell hardness 25~135 HB.
* High sensitivity. The Wechsler hardness meter has only 20 scales, while the Pasteur hardness meter test range 0-100, with higher sensitivity.
* Without support, it is suitable for testing oversize and overthick workpieces and assembly parts.
