Auto True Density Analyzer

SI-2000TD-K automatic open and closed porosity true density analyzer uses computer-controlled automatic operation of the gas expander true density analysis system, with a number of technology patents, the original test mode, so that a wider application area than similar instrument , can accurately determine true density, density and porosity of the powder, bulk solids, syrupy substance, foam and other materials,

Features and Benefits

1. open closed porosity dedicated sample cell: a sample cell foam material specifically meet the national standard GB / T 10799-2008 and design, stainless steel, the interior space of a cube, can sample cell utilization rate (more than 80% of the national standard more than 15%), much higher than ordinary cylindrical sample cell;
2. Test method: different volumes of sample cell as a sample test chamber "downloading" type of test mode, relative to similar instruments by filling way to change the way the test chamber volume, with the sample test chamber volume high utilization advantage, so that the test accuracy can be improved; "Bottoms bayonet," the sample cell, can meet the micro-volume and large volume sample loading demand convenience, in order to achieve the purpose of improving the accuracy of the test;

(Patent Title: having a sample cell directly as real test chamber densimeter Patent No.: 201120436207.5)

1.  Valve Type: gas control valves, fundamentally eliminate the solenoid valve structure similar instrument operation when the heat caused by the temperature change of the reference cavity and temperature non-uniformity, ensuring the ideal temperature effect; the use of software to subvert the fundamental Fixed way to reduce electromagnetic valve damage thermostat heating effect caused by error;

1. modular manifold: no air passage between the modular structure, valves and valve pipe joints, reducing the leakage point, temperature field uniformity;
2. Auto Repeat: You can automatically repeat the test until the specified accuracy;
3. pressure balance: with automatic default, and the user selects a user-defined three modes of pressure equilibration time to adapt to the structural state of the sample do not;
4. self-test process: advanced intelligent self-test process, intelligent judgment sample cell for leaks and instrument tightness is qualified to solve human error;
5.  restore normal pressure: a pressure test is completed automatically restore function to prevent splashing the sample;
6. Control Interface: a clear image of graphical control interface, and can perform all operations on the hardware control interface;
7. power protection: super stability, even if unexpected power outages, break, and will not lose the current data, and experiments recoverable proceed;
8. Memory function: the instrument configuration parameters is written directly to the instrument hardware chip, stored permanently, and reinstall the system, do not worry instrument parameters are missing or incorrectly configured, to achieve zero artificial instrument hardware configuration parameters;
9. Run Log: detailed running log instrument time accurate to the second, the log for the reliable operation of the instrument to provide protection and after-sale;

 live voice: each test process real voice prompts;

1. Multi-language package: support customizable editable multi-language interface;
2. Remote Control: a network remote control function;

Performance parameters
