Description:
A face mask which need to filter virus, it will need to capture less than 0.3um diameter particle. But it may affer the air for breathing. As a result, the face mask has charged electrostatic to the face mask, to regconize a real or fake face mask. We can simply to use the static voltage to check whether it is good or fake.
A good face mask, has electrostatic voltage can be measured by our JED100 handheld static meter.
While we move close to the face maks, it will light up the Blue or Red Led. But a fake or bad quality face mask, there is no electrostatic voltage stored inside the electret, cause, they don't have electret inside the fake face mask.
So we can use our low cost meter to recognize the face mask quality.
Also while the face mask's storage environment humidity is too high, or used for long time, it will also lose the electrostatic charge from electret.
This electrostatic detector can be used in the qualitative measurement of whether there is static electricity on the surface of the target object. It is widely used in the measurement of static electricity on the surface of masks, non-woven fabrics, plastics, films, rubber, fiber composite plates and other products.
Features:
Professional Electrostatic Tester: non-contact electrostatic qualitative testing gauge for quickly detecting the surface static of the object.
Mini Palm Size: easy to operate by single hand, convenient to carry around.
Three Indicator Light: green for power, red for positive charge and blue for negative charge.
Power Supply: powered by 2pcs CR2030 battery, low power consumption.
Wide Applications: it is widely used in the measurement of static electricity on the surface of masks, non-woven fabrics, plastics, films, rubber, fiber composite plates and other products.
