During a recent Isotech seminar, twenty experienced engineers from many parts of the world were asked to produce their ideal specification for industrial Dry Block Calibrators. Their top ten requirements, in order of priority, were; 1. Rugged 2. Light weight 3. Easy to use on site 4. Low cost/high benefit ratio 5. Fast response, high stability 6. Time saving features 7. Multiple sensor testing 8. Software 9. Modern design 10. Compliant with the latest regulations. The result is the new range of Fast-Cal Dry Block Calibrators.
