If you are looking for a universal testing machine (UTM) to perform tensile, compression, bending and other mechanical tests on materials, you may wonder whether to choose an electronic or a hydraulic one. In this blog post, we will compare the main features and advantages of both types of UTM.

Electronic universal testing machine (EUTM) uses an electric motor to apply force through a screw mechanism. It can achieve high accuracy and precision in measuring force, displacement and strain. It can also control the test speed and displacement with ease. EUTM is suitable for testing materials that require low to medium force levels, such as plastics, rubber, textiles and metals.

Hydraulic universal testing machine (HUTM) uses a hydraulic pump to apply force through a piston-cylinder system. It can achieve high force capacity and stability in loading. It can also handle large specimens and dynamic tests. HUTM is suitable for testing materials that require high force levels, such as concrete, steel, wood and composite materials.

Both EUTM and HUTM have their own pros and cons depending on the application and requirements. Some factors to consider when choosing between them are:

- Test range: EUTM can cover a wider range of force levels than HUTM, but HUTM can reach higher maximum force than EUTM.
- Test speed: EUTM can adjust the test speed more precisely than HUTM, but HUTM can achieve faster loading rates than EUTM.
- Test accuracy: EUTM can measure the test parameters more accurately than HUTM, but HUTM can maintain the load more stably than EUTM.
- Test cost: EUTM has lower maintenance and operation costs than HUTM, but HUTM has lower initial purchase costs than EUTM.

To summarize, EUTM and HUTM are both useful tools for material testing, but they have different strengths and limitations. You should choose the one that best suits your needs based on your budget, test specifications and quality standards.
