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.
Guildline Instruments 5600 SERIES is the latest in high precision fluid/oil baths providing uniform constant fluid temperature over a range from -5 °C to 55 °C. This Series of Fluid Baths is designed for both metrology and oceanographic applications and can be used with oil, water, salt water, or other liquids.
Guildline's 6624CT-3000 DC High Current Transformer provides very accurate DC current measurements up to 3000 Amperes. The direct current transformer is designed with an open window to pass a single cable, set of cables, or buss bar that carry the direct current to be measured. The 6624CT-3000 High Current DC Current Transformer produces an output current that varies directly with the input current in three ranges.
Guildline Instrument’s 6625A-QHR System has been designed and developed to meet the needs of Standards Laboratories around the world for an improved level of accuracy in the calibration and maintenance of primary resistance standards
Guildline Instruments 6622A-QHR Resistance DCC Bridge has been designed to provide better uncertainties and more operational capability in Direct Current Comparator (DCC) Resistance Bridges used with Quantum Hall Resistance Systems (i.e. QHRs).
GUILDLINE’S NEW 6640T SERIES OF TEMPERATURE BRIDGES is a completely redesigned DCC Temperature Bridge to provide better uncertainties, faster measurement rates and more operational capability.
