1594A / 1595A Super-Thermometers
Combine the accuracy of complex and expensive bridges with innovative features that simplify measurement processes and provide excellent value
The Fluke Calibration 1594A and 1595A Super-Thermometers combine the accuracy of complex and expensive bridges with innovative features that simplify measurement processes and provide excellent value. They are accurate enough for the primary lab and economical enough for the secondary lab. With temperature-controlled internal reference resistors, six input channels, a large graphical display, and a multitude of temperature-specific measurement functions, PRT, thermistor and SPRT calibration (0 Ω - 500 kΩ) has never been so easy and economical. And with the built-in Ratio Self-Calibration function, you can verify or calibrate the Super-Thermometer’s ratio accuracy in-house with the press of a button—no other single thermometry bridge can do so much, so well!
• Calibrate SPRTs, PRTs, RTDs and thermistors (0 Ω - 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 multichannel, real-time data acquisition software
• Includes NVLAP-accredited certificate of calibration, User’s guide, Technical guide (English only on CD-ROM), RS-232 to USB converter cable, and regional power cord
