The electrometer was tested in both air and vacuum at room temperature. Since then, it has evolved to include various subsidiaries in different market sectors including El Sewedy Electrometer. Blast Equipment. http://wwwcom/products/dcac/voltagesource/application/?mn=6517B How to Make a Proper Low Current Measurement with the Model 6517B Electrometer MET's Electric Meter Certification Program provides the testing and certification manufacturers' need for entry into global markets. A value of ‑3 dB means that signals are. The reading is taken on a quadrant graduated in degrees. View and Download Keithley 617 instruction manual online. The instrument utilizes flash memory, allowing instrument updates to be distributed electronically instead of the inconvenient shipment and installation of an EPROM chip. The Lindemann electrometer is essentially a quadrant electrometer. An electrometer is a type of sensor that can precisely measure small or large quantities of electric charge. This, combined with the mil gauge's ability to measure up to 13mm (500mils) of coating on metal substrates, as well its compatibility with ElcoMaster ® software, ensures it is a highly powerful solution to measuring dry film thickness on large surfaces.

An electrometer is an electrical scientific instrument that is used to measure a small electric charge or electric potential difference between two points. Many devices can measure voltage and charges with very-low leakage currents to 1 femtoampere (fA) or less.
