Linear Wear Testing MachineTest standards: ASTMF2495, F2496, ISO1518, GME60248, GME60368, D42 1775

The wear tester includes a balancing arm that can rotate along a height adjustable crossbeam. The balancing weight is used to balance the testing arm, ensuring accurate testing load without being affected by accessory weight. The end of the testing arm is a clamp used to fix weights and testing accessories, and the sample stage moves horizontally back and forth below. The reciprocating wear tester is suitable for measuring flat surfaces and is equipped with optional accessories to test the surface resistance of materials. For most flat samples, sample clamps or optional wide slot fixing plates can meet the requirements. For flexible materials such as textiles, optional sample fixing plates can be used. For products with slight curved surfaces, random sample clamps or customized fixtures can be used to fix them.

Testing method:

1. Install the sample, fix the sample, select the grinding head, and install the grinding head into the lower end of the weight rod.

2. Adjust to an approximate level and bring the grinding head into contact with the test surface

3. Turn on the power, enter settings, and set the number of times. Automatically shut down after the set number of times.

4. After the test is completed, remove the sample for observation.

5.Infrared carbon dioxide analyzer/Infrared carbon dioxide detectorH18434

Instrument Overview
The infrared carbon dioxide analyzer is an intelligent infrared carbon dioxide analyzer developed based on the infrared analysis method in GB/T12960-2019 "Quantitative Determination of Cement Components". The measurement principle is that the sample is decomposed by an acidic solution, and the generated carbon dioxide gas is sensed by an infrared carbon dioxide sensor to obtain the content of carbon dioxide, thereby calculating the content of limestone components in the sample.
