Keyence SK-H050 High-Precision Electrostatic sensor
**Unit has been tested to specifications. Batteries not included. Unit has missing power cord and Electrostatic sensor. See photos for further details.
The SK Series electrostatic sensor measures static electricity and humidity at the same time. Because static electricity generation is closely related to humidity, the SK Series can determine the electric charge of the area around the target while understanding environmental conditions. Whereas conventional static electricity measuring instruments are prone to errors if the distance to the target changes, inline SK Series devices can correct static electricity measurements according to the target distance. Hand-held types are also available if measurement is needed at multiple points along a process. The SK Series various functions allow users to obtain a detailed, accurate understanding of the conditions in areas prone to static electricity problems.
