Fluke Calibration 9009-B-156 Industrial Dual-Block Thermometer Dry-Well Calibrator with Two 1/4" and Two 3/16" Inserts, Black Case, 110V, 50/60Hz

The Model 9009 includes two independently controlled temperature blocks. The hot block provides temperatures from 50°C to 350°C, while the cold block covers the range –15°C to 110°C. Each block is controlled by a precision Fluke Calibration temperature controller. These aren’t some off-the-shelf controllers we glued into a box. These are Fluke Calibration controllers from the leading temperature company in the world. Each temperature block includes two wells with removable inserts. You can calibrate four probes at once, or you can calibrate two probes at the same time with an external reference like Fluke Calibration's Model 1523 Reference Thermometer, or you can use the two temperature wells to get quick “zero" and “span" references for transmitter calibrations.
