1594A and 1595A Super-Thermometer Bridge

• Calibrate SPRTs, PRTs, RTDs and thermistors (0 Ω to 500 kΩ)
• Accuracy as good as 0.06 ppm (0.000015 °C)
• “Ratio Self-Calibration” verifies and calibrates resistance ratio accuracy
• Automatic zero-power measurements calculate thermometer probe self-heating
• Temperature-controlled internal reference resistors
• Calibrated sensing current lowers overall instrument uncertainty
• Four input channels on the front panel accept sensors under test or external references
• Two dedicated external reference input channels on the rear panel
• Standby current reduces transient effects when scanning between channels
• Channel Select keys turn measurement mode on or off at the touch of a button
• Sample rates as fast as one second
• USB data transfer and computer control
• Remote view and device control via Ethernet
• Compatible with MET/TEMP II automated calibration software and LogWare II multi-channel, real-time data acquisition software

The Fluke 1594A and 1595A Super-Thermometers from Hart Scientific combine the accuracy of complex and expensive thermometry bridges with innovative features that simplify measurement processes and provide excellent value.
