Datasheet
Download datasheet (PDF)Description
The Fluke Calibration 7508, 7511 and 7512 refrigerated temperature calibration baths deliver exceptional temperature stability and uniformity at low temperatures down to -10 °C. They are used by national labs for comparison calibrations and fixed-point cell maintenance.
The range of available bath sizes lets you calibrate a wide variety of platinum resistance thermometers (PRTs), thermistors and thermocouples, as well as triple-point-of-water cells and blackbody cones.
Each bath is fully automated with a bath interface package and Fluke Calibration MET/TEMP II automation software, controlled from a PC over USB or RS-232 through a 1586A Super-DAQ. Direct-drive stirrer motors and full fluid drainage make maintenance easy, and the baths use CFC-free refrigerants.
