MDY500 Fully Automatic Density MeterPerformance Features and Technical Parameters

MDY500 Fully Automatic Density Meter Testing Accuracy: Precision better than ±0.0005%, repeatability better than ±0.0001, resolution: 0.0001g/ml;
Test accuracy for the same sample: ±0.0005;
Testing Speed: Completes the entire testing process within 3 minutes, with automatic data calculation, saving, and printing;
Measurable Parameters: True density, true volume, porosity;
Testing Volume: 10ml and above, suitable for samples of various sizes;
Pressure Range: 0-1 bar. Users can customize the maximum pressure to reduce errors caused by sample deformation under pressure;
Testing Gas: High-purity helium, purity ≥99.999%; avoids interference from other gases affecting experimental results;
Degassing Device: Achieves rapid degassing, reaching 100Pa in 5 minutes. Negative pressure degassing ensures thorough gas removal from samples, resulting in higher purity of the testing gas and more accurate test data;
Fully Automated Operation: One-click completion of gas path flushing, sample flushing, multiple repeated tests, and automatic sample calculation;
Valve Type: The intake testing system uses pneumatic valves, fundamentally preventing temperature changes and unevenness in the reference chamber caused by heat from electromagnetic valve structures, ensuring ideal constant temperature effects. This eliminates errors from software corrections to mitigate heat-induced temperature fluctuations. The exhaust system uses imported electromagnetic valves for automatic control, reducing human operational errors;
Equipped with Constant Temperature Function: Range: 0-100°C, precision: ±0.1°C;
Utilizes a 32-bit ARM Cortex core processor and a self-developed industrial-grade multi-layer circuit motherboard for high operational speed;
Data Acquisition: Uses a 24-bit high-precision chip for highly accurate and stable temperature and pressure data collection;
Employs imported high-precision sensors for precise switching control time and high consistency;
Intelligent Power Failure Protection: Automatically closes the intake valve in case of sudden power failure to ensure equipment safety;
Data Backup Function: When the PC malfunctions, the device can store data without interrupting the experiment;
Automatic Sample Filtration and Gas Flow Control: Prevents fine particles from entering the testing pipeline and valves, ensuring testing accuracy and airtightness;
Constant Temperature Water Tank with Intelligent Control: Automatically refills water without manual intervention, preventing dry burning.
