The 6664C Low Thermal Quad Scanner has the Highest Isolation of any 4-Terminal Scanner and operates at up to 1000V. With a Guildline model 6664C scanner and software, hard-to-make high ohm measurements (up to 100 GΩ) can be automated and scheduled at any time that is convenient to the metrologists, even at night and over the weekends.


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's NEW 3210 Series of Thermometry Auto-Switch with Pre-Heat automates temperature measurements including fixed points and thermometer calibrations.   Up to eight PRTs or other temperature devices can be connected with individually programmable DC currents from 20 µA to 150 mA.
