The DRK151 electrostatic voltage tester is suitable for measuring the electrostatic voltage of charged objects and is an ideal instrument for on-site electrostatic detection. Features It can measure the liquid surface potential and detect the performance of anti-static products. It is suitable for measuring the electrostatic voltage (potential) of charged objects, such as the electrostatic potential of conductors, insulators, and human bodies. It can also measure the liquid surface potential and detect the performance of anti-static products. It is an ideal instrument for on-site electrostatic detection. Applications It is suitable for measuring the electrostatic voltage (potential) of charged objects, such as the electrostatic potential of conductors, insulators, and human bodies. It can also measure the liquid surface potential and detect the performance of anti-static products. It is widely used in the measurement of static electricity in the scientific research, production, storage and transportation safety management departments of petroleum, chemical industry, oil depot, fire protection, electronics, national defense, aerospace, natural gas, printing, textile, printing and dyeing, rubber, plastics, spraying, medicine, etc. It is an ideal instrument for on-site electrostatic detection. Product Parameter 1.3-digit semi-liquid crystal digital display, automatically display the measured static voltage value 2. The measuring ruler with a length of 25.4 mm (1 inch) is suitable for repetitive static voltage measurement 3. Automatically distinguish the polarity of the static voltage, when the surface of the static electricity object is negative, it can show the negative polarity 4. Battery capacity indicator "BAT" 5. Measured value sampling hold button 6. Multi-range, the relationship between the static voltage value and the measured distance @1 inch: 0-20,000 volts, 100 volts carry @1/10 inches: 0-2, 000 volts, 10 volts carry @4 inches: ±40,000 volts, multiply the reading display by 2 @6.5 inches: ±60,000 volts, multiply the reading display by 3 @8.5 inches: ±80,000 volts, multiply the reading by 4 7. The watch forms a grounding path through the case of anti-static material 8. Standard 9 volt battery 9. One-year warranty, the warranty will automatically become invalid after the case is opened 10. The highest measured value under standard conditions is 20,000 volts 11. Measurement accuracy ±10% 12. A calibration certificate conforming to NIST is provided with the meter free of charge 13.DRK-151 leather case 14.Weight 5 ounces 1. Size 107mm×61mm×23mm Product Configuration One host, one manual
