Fluke Calibration 5606 [5606-50-A] Full Immersion PRT Probe –200 to 160 °C

The Fluke Calibration 1502A256 Tweener Thermometer Readout for RTD, RTD and SPRT Probes features accuracy up to ±0.006 °C. In addition, it reads 100-ohm, 25-ohm, and 10-ohm probes, and has a resolution of 0.001 °C across its entire range. It also has an optional battery pack for completely portable operation.

Each Tweener is programmable to match a probe's constants for maximum linearity and accuracy. All probe constants and coefficients are programmed through simple, front-panel keystrokes. Temperature is displayed in °C, °F, K, or resistance in ohms.

The Fluke Calibration 1502A-256 accurately measures the resistance of the probe and then converts the resistance into a temperature value, using its built-in algorithms.

For convenience, the 1502A-256 reads the common industrial grade IEC-751 or "385" ALPHA RTD without any programming. Enter the actual R0 and ALPHA of the individual probe for increased accuracy. For maximum accuracy, use the ITS-90 formulas. The 1502A-256 accepts the subranges 4 and 6 through 11.

ITS-90 formulas reside in the Tweener's firmware. If your probe has been calibrated for any of the above subranges of the ITS-90, you simply enter the coefficients directly into the 1502A-256 unit.

The 1502A-256 comes complete with an RS-232 interface for automation of temperature data collection, calibrations, or process control functions. An IEEE-488 interface is also an available option.

The Fluke Calibration 1502A-156 is calibrated digitally using the front-panel buttons. You never have to open the box to calibrate it. This calibration protocol further reduces the cost of this unit; it goes where you go and works the way that you want it to.
