The 6564 High to Ultra-High Resistance Scanner is the only Scanner capable of operating with measurements to 10 PΩ’s (1015) and at voltages to 1000 Vdc. The 6564 has world-leading isolation of 1017 with repeatable offsets above this resistance. Researchers and Metrologists can now easily and quickly automate single or multiple resistance measurements.

GUILDLINE Instruments 6530 TeraOhm Bridge-Meter Series is the latest innovation in High Resistance and Ultra-High Resistance Measurements. These Bridge-Meters incorporate the latest technology for high resistance measurements providing Metrologists with measurement results superior to that of commerciallyavailable Dual Source Bridges. The 6530 Series allows users to make Direct Resistance Measurements as well as Bridge Ratio Measurements up to 20 PΩ with the best uncertainties above 1 GΩ of any commercially available resistance measurement instrument.
