产品介绍

1. Product instruction:

NJ-LSY concrete sulfate dry and wet cycle testing machine is a product developed according to GB/T50082-2009. The product is suitable for measuring the sulfate resistance of concrete specimens in alternating dry and wet environment, expressed by the number of dry and wet cycles they can withstand. After the test parameters are set, the test process is carried out automatically, and it is the equipment for testing the concrete specimen's resistance to sulfate attack.

2. Product features:

1). microcomputer control, can be completely independent from the computer work. Memory Settings can store multiple sets of historical data;

2). In the test, the LCD screen can display real-time dynamic data and monitor the working status of the equipment;

3). fully enclosed compressor, stable and reliable operation.

4). solid state relay control, no electric field and magnetic field interference, can ensure long-term stable operation;

5). stainless steel manufactured, longer life than ordinary stainless steel, more resistant to corrosion.

6). valves, pipelines, sensors, circulating pumps, solenoid valves, liquid reservoirs and other devices, all adopt anti-corrosion design.

7). thermal insulation using thermal insulation rock wool.

8). automatically complete soaking, drying, drying and cooling cycle process.

9). the test data power off recovery function, when the test process is unexpectedly stopped, it can continue to run after starting again.
