ZKZMD-10 Powder True Density Meter Introduction: The testing system of the powder true density meter consists of a sample testing chamber and a reference chamber. When measuring the true density of the sample, the instrument automatically collects the pressure P1 and volume V1 of the reference chamber and records them; Place a sample V with a certain unknown volume into a sample testing chamber with a known volume V2, inject a certain amount of gas into the sample testing chamber, and record the stable pressure P2; Connect the sample testing chamber to the reference chamber and record the stable pressure P3. Based on the equilibrium stable pressure value and the relevant known volumes V1 and V2, the volume of the sample to be tested V can be calculated. Then, the true density of the sample can be calculated from the mass and volume of the sample. characteristic: 1. Adapt to the measurement needs of different samples such as block, granular, powdery, liquid, etc; 2. The automatic repeated measurement state can be run repeatedly; 3. The pressure balance time can be set flexibly by the user; 4. Analyze that the running time is only a few minutes; 5. For the user selected number of cycles and scheduled cleaning, there is a pulse signal (pressure/pressure reduction) for the sample preparation/cleaning status; 6. Comes with RS485, RJ45, and mini printer for easy data transfer to printer (TMS model) or PC (PNS model); 7. There are user selectable high pressures that can eliminate the harm caused by sample deformation during analysis; 8. Automatically print data reports (TMS version), including statistical analysis results, sample numbers, and operating conditions. Technical parameters: Test principle: Archimedes' principle (gas displacement method) Test accuracy: better than 5 ‰ Repeatability: Relative standard *. 1~0.3% Test resolution: 0.01mL Pressure relief valve: 154N-050A-C Solenoid valve: CFVB25-Z-O-B2C-3 Sample pool volume: 10mL Test time:~4min/time Input voltage: AC 220V/50Hz Rated power: 28W Appearance dimensions: 410mm × 320mm × 155mm Weight: 4.6 kg working pressure: 1.3 bar Atmospheric pressure: 2.0 bar Analyze gas: He/N2 Input method: Touch screen handwriting input Data output: process recording+USB data storage
