How are readings affected by the distance between the instrument and the material?
The company publishes no measurement procedure, so it states nothing about how the distance to the material affects a reading.
The polarity is a positive electric charge at rest, and it is measured as surface charge density, in nanocoulombs per square centimetre. The company publishes no measurement procedure, no instrument record and no uncertainty budget. How a reading is taken is a method, and the company publishes none. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
