Guildline’s 6564 High to Ultra-High Resistance Scanners are the first commercial scanners capable of operating with measurement capabilities to 10 PΩ’s and at voltages to 1000 Vdc. This capability greatly improves the measurement and calibration throughput of high and ultra-high ohm resistance measurements. Standard laboratories can easily and quickly automate measuring single or multiple resistance values.
