How to check the performance of the ion fan
1. Use the electrostatic voltmeter method to rub the surface of the anti-static equipment with nylon cloth or plastic, and measure its surface potential with a cheap and easy-to-use electrostatic voltmeter. If the electrification is very low several hundred volts and it will soon decrease or The indication of the electrostatic meter is almost 0, so its performance is good; if the electrification voltage is high, such as several thousand volts or tens of thousands of volts, and it can hardly drop for a long time (several seconds or longer), measure its antistatic performance difference.
2. Using the megohmmeter and electrode method The static surface resistivity of general antistatic equipment is in the range of 106-109Ω, which is a good product. The test voltage is usually 100V or 500V. Therefore, megohmmeters and electrodes can be used for measurement. Because the electrode size and weight have a great influence on the measurement results when measuring the surface resistance. Therefore, when using non-standard electrodes for measurement, the error is sometimes large.
