VERMASON VER-29206 静电场测试仪, 5%, 数字式
The is a Digital Static Field Meter with high quality and portable non-contacting static field which consistently produces accurate readings with ease and provides years of trouble-free operation. The digital static field meter indicates surface voltage and polarity on objects up to ±19.99kV at a distance of 1-inch with an accuracy of ±5% of the displayed value. It is chopper-stabilised for use under almost any condition including ionised environments. The conductive case and ground snap facilitate grounding for accurate measurement. Also featured are a zero button and a display hold function. Unique LED rangefinder system provides accurate positioning of the meter from the target. It is built-in a conductive case. The instrument senses the difference in potential between the case and the surface under test. Ensure that the person using the instrument is grounded or that the rear panel ground snap connection is used to achieve accurate measurements.
