This instrument is used to determine the electrostatic performance (static attenuation) of medical protective clothing Applicable Standards: GB19082-2009 technical requirements for medical protective clothing, YY-T1498-2016 selection guide for medical protective clothing, GB/T12703 textile static electricity test method Technical Description: This instrument adopts the corona discharge test mechanism and is suitable for measuring the electrostatic properties of fabrics, yarns, fibers and other textile materials. The instrument is controlled by a microcomputer with a 16-bit high-speed and high-precision ADC, which automatically completes the high-voltage discharge of the tested sample, the data collection, processing and display of the electrostatic voltage value (accurate to 1V), the electrostatic voltage half-life value and the decay time. The performance of the instrument is stable and reliable, and the operation is simple. Technical Parameters: 1. Test method: timing method, constant pressure method; 2. It adopts microprocessor control, automatically completes sensor calibration, and prints and outputs the results. 3. The digital control high-voltage power supply adopts DA linear control output and only needs digital setting. 4. Voltage pressure range: 0～10KV. 5. Measuring range: 100～7000V±2%. 6. Half-life time limit: 0～9999.9 seconds ± 0.1 seconds. 7. Turntable speed: 1500 rpm 8. Dimensions: 700mm×500mm×450mm 9. Power supply voltage: AC220v, 50Hz 10. Instrument weight: 50kg
