Portable Static Meter - Battery Operated
Kernco Instruments Co. Inc. is pleased to introduce its Model 7905 Static Meter a battery operated unit (1 each 9V battery), designed to detect static charges and finding the exact point where the static is generated.
The Model 7905 Static Meter is a high quality, portable, non-contacting static meter which will produce years of trouble-free operation. It will indicate surface voltage and polarity on objects up to ± 20kV at a spacing of one inch with an accuracy of 10% full scale. Also featured are a pushbutton to hold readings and automatic power down to conserve the battery.
The accuracy is dependent upon three factors:
*The instrument must be properly zeroed.
*The distance from the front edge of the case to the target or surface under examination must be accurately defined.
*The target must be large - relative to the measurement distance. It should be at least 5" x 5" (12.7 cm x 12.7 cm) for true accuracy.
Specifications:
Range: 0 to ± 20kV at 1"
Distance: The meter reads true at 1" from the test surface
Accuracy: + 10% of full scale
Power: (1) 9Volt Battery (Battery Life: 200 Hrs.)
Size: 4.14"L (10.6cm), 2.4"W (6.1cm), 1"Th (2.5cm)
Color: Black
Weight: Approximately 1/4 pound (1/13g)
